DIAGNOSTIC ROUTINE(S)


PINPOINT TEST A : P064F:00, P06B8:00

Refer to Wiring Diagrams Cell 12 for schematic and connector information.

Normal Operation and Fault Conditions

When powered on, the SOBDM validates internal software and loads the NVRAM (nonvolatile random-access memory) parameters. If the SOBDM detects the software checksum does not match DTC P064F:00 sets or a NVRAM error occurs DTC P06B8:00 sets. Presence of either DTC illuminates the Charger Service Required indicator in the IPC. DTC P064F:00 results in the CSI (Charge Status Indicator) flashing a fault pattern and the vehicle will not charge.

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
SOBDM P064F:00 Unauthorized Software/Calibration Detected: No Sub Type Information Sets if SOBDM detects unauthorized software.
SOBDM P06B8:00 Internal Control Module Non-Volatile Random Access Memory (NVRAM) Error: No Sub Type Information Sets if SOBDM detects an NVRAM error.

Yes CARRY OUT PMI on the SOBDM.
REFER to: Module Programming (418-01 Module Configuration, General Procedures).
If the concern is still present, CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new SOBDM.
REFER to: Secondary On-Board Diagnostic Control Module A (SOBDM) - Plug-In Hybrid Electric Vehicle (PHEV) (414-03B High Voltage Battery Charging System, Removal and Installation).
No The concern is not present at this time.

PINPOINT TEST B : P0A1F:00

Refer to Wiring Diagrams Cell 12 for schematic and connector information.

Normal Operation and Fault Conditions

When the EVSE is plugged into the vehicle charge port the SOBDM monitors the charging system current and voltage requests from the BECM via HS-CAN for rationality faults. If the BECM charging current and voltage requests exceed the BECM maximum charging current and voltage request or if the BECM remains in charge wait status for over 30 seconds. This DTC results in the CSI (Charge Status Indicator) flashing a fault pattern and the vehicle will not charge.

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
SOBDM P0A1F:00 Battery Energy Control Module "A" Performance: No Sub Type Information This DTC sets when the charging parameters from the BECM fail a rationality check and/or the BECM does not transition from a charge wait status for 30 seconds.

No CLEAR the SOBDM DTC and test the system for normal operation by connecting a known good EVSE to the vehicle. The concern may be related to a faulty EVSE being used or an intermittent fault condition.

PINPOINT TEST C : P0CF4:29, P0CF4:77, P0CF5:00, P0CF7:00, P0D2B:38

Refer to Wiring Diagrams Cell 12 for schematic and connector information.

Normal Operation and Fault Conditions

When the EVSE (Electric Vehicle Supply Equipment) is plugged into the vehicle charge port the EVSE sends a 12-volt static pilot voltage signal to the SOBDM to wake it up. When plugged into an EVSE, a vehicle connects the pilot output to the supply ground through a resistor/diode combination, bringing the pilot test point voltages into the range of a valid response. If the EVSE detects a valid voltage range it will send out a 1KHz square wave and notify the SOBDM that it is ready to send energy. The EVSE adjusts the duty cycle to convey the available AC line current. The SOBDM analyzes the pilot signal duty cycle to determine AC line capacity and the frequency and to make sure it is in the proper range.

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
SOBDM P0CF4:29 Control Pilot Circuit Range/Performance: Signal Invalid This DTC sets when the SOBDM senses that the pilot signal duty cycle is between 7% - 8% for 5 seconds when charger is in ready state. This DTC is the result of using a faulty EVSE. Consult with customer to determine which EVSE was used when the fault occurred. If fault occurred with a level 1 (110V) EVSE ask customer to provide it for testing. Five consecutive failures are required to set charger service required message in the IPC
SOBDM P0CF4:77 Control Pilot Circuit Range/Performance: Commanded Position Not Reachable This DTC sets when the SOBDM senses that the pilot signal duty cycle is between 3% - 7% for 5 seconds when charger is in ready state. This DTC is the result of using an incompatible EVSE. Consult with customer to determine which EVSE was used when the fault occurred. If fault occurred with a level 1 (110V) EVSE ask customer to provide it for testing. Five consecutive failures are required to set charger service required message in the IPC
SOBDM P0CF5:00 Control Pilot Circuit Low: No Sub Type Information Sets while the vehicle is on On-Plug if SOBDM detects the pilot signal duty cycle is between 0% - 3% for 5 seconds after 5 monitoring cycles.
SOBDM P0CF7:00 Control Pilot Circuit Intermittent/Erratic: No Sub Type Information Sets while the vehicle is on On-Plug if the SOBDM detects the pilot signal is present but not stable for 10 seconds.
SOBDM P0D2B:38 Control Pilot Indicator Control Circuit/Open: Signal Frequency Incorrect This DTC sets when the EVSE control pilot frequency is less than 950Hz or greater than 1050Hz for 5 seconds. This DTC is related to a faulty or incompatible EVSE. Consult with customer to determine which EVSE was used when the fault occurred. If fault occurred with a level 1 (110V) EVSE ask customer to provide it for testing.

Refer to Wiring Diagrams Cell 12 for schematic and connector information.

Normal Operation and Fault Conditions

The SOBDM is liquid cooled by the motor electronics cooling system that consists of a radiator, coolant hoses, and a coolant pump. The SOBDM monitors its temperature internally. SOBDM requests a coolant flow speed and monitors the coolant pump status from the BECM via HS-CAN. If the temperature increases higher than a calibrated threshold, a P0D8F:00 sets and charging is derated. This DTC is often the result of high environmental temperatures. If the temperature becomes excessive, DTC P0D24:00 sets. The SOBDM stops charging and goes to a fault status until the over-temperature condition clears. Presence of this DTC illuminates the Charger Service Required indicator in the IPC.

Normal Operation and Fault Conditions

The SOBDM monitors the proximity voltage signal when an EVSE is connected to the vehicle's charge port and during driving. The proximity voltage is used to verify three functions of the charge port. First, it verifies the EVSE connection is stable and not damaged. Second, provides connection information to the drive interlock system. Third, the proximity voltage provides a signal in the vehicle charge control strategy to help reduce electrical arcing of the coupler during disconnect by using a S3 switch. The S3 switch is the coupler release button that is mechanically linked to the connector latch release actuator. The S3 switch is normally closed at all times except when the connector latch release actuator is pressed to decouple the connector from the vehicle inlet. Opening of the S3 switch triggers the vehicle charge control to provide a controlled shutoff of charge power prior to disconnecting the EVSE. The proximity circuit voltage is continuously monitored for faults. Proximity faults will not prevent the vehicle from charging.

Normal Operation and Fault Conditions

During high voltage battery charging it is a requirement to lock the cord to the charge port to avoid exposure to high voltage. The charge port is equipped with a locking pin actuator that locks and unlocks the charger plug. The locking pin extends to lock the plug or retracts to unlock the plug. the There are 2 actuator circuits and 1 actuator position sensor circuit that are hardwired to the SOBDM. The SOBDM actuates the locking pin to either the locked position (extracted) or unlocked position (retracted) and continuously monitors the pin position using two digital sense circuits. The SOBDM monitors each circuit for faults and monitors the pin for unlock and lock failures. If a fault occurs during charging, charging will be aborted and the Charge Status Indicator (CSI) LED's will flash. High voltage battery charging will be disabled until the fault is corrected. Presence of these DTCs illuminates the Charger Service Required indicator in the IPC.

PINPOINT TEST AF : A MODULE DOES NOT RESPOND TO A DIAGNOSTIC SCAN TOOL AFTER ATTEMPTING TO PROGRAM OR CONFIGURE THE MODULE

Normal Operation and Fault Conditions

A modules calibration file is a complex data file that tells the module how to operate similar to a computers operating system. When programming or configuring a module the scan tool erases the current file and uploads the same or newer calibration file to the module's EEPROM chip. During the file upload an error occurs during the flash the module will be in an unusable state and appear to be faulty and not communicate with the scan tool. If this occurs the cause of the error or interruption either related to the vehicle or scan tool (e.g. low 12-volt battery, faulty cable etc..) must first be addressed and module programming can be attempted again. If module completes successfully the full the module will be returned to its previous functional state of operation.

PINPOINT TEST AX : CSI (CHARGE STATUS INDICATOR) LED (LIGHT EMITTING DIODE) SEGMENTS ARE INOPERATIVE OR INDICATE A CHARGING STATUS FAULT

Refer to Wiring Diagrams Cell 12 for schematic and connector information.

Normal Operation and Fault Conditions

When an EVSE (Electric Vehicle Supply Equipment) is plugged into the vehicle charge port the CSI (Charge Status Indicator) indicates the current Customer State-of-Charge (CSoC) and charging operations of the high voltage battery. The CSI is a light bar surrounding the charge port inlet that displays charging, charging faults and charging status using five LED light segment sections. The CSI is connected to and operated by the SOBDM over a LIN circuit. Each segment of the CSI indicates 20% Customer State-of-Charge (CSoC) during charging. If the SOBDM detects a vehicle charging fault it will send a signal to the CSI (Charge Status Indicator) to flash all LED light segments simultaneously.

Possible Sources

  • Charge Status Indicator (CSI) selectable preference in APIM
  • Fuse(s)
  • Wiring, terminals or connectors
  • Charge Status Indicator (CSI)

PINPOINT TEST AY : LENGTH OF CHARGE IS EXCESSIVE

Refer to Wiring Diagrams Cell 12 for schematic and connector information.

Normal Operation and Fault Conditions

The amount of time required to fully charge the high voltage battery depends on many different factors, including:

  • Type of Electrical Vehicle Supply Equipment (EVSE) - Different EVSE's support different charge rates.
  • Temperature of high voltage battery - Extreme ambient temperatures reduces the charge rate of the high voltage battery.
  • Cabin Pre-conditioning (remote start) - When requested the vehicle preconditions the cabin temperature prior to vehicle use. The electricity that would normally be used to charge the battery is used for operating the cabin coolant heater and blower motor to warm the interior, or the ACCM and blower motor to keep the interior cool.
  • Initial high voltage battery SOC (State of Charge) - If the high voltage battery state of charge is depleted to 10%, it takes longer to charge to 100% than it takes to charge a high voltage battery from 50% to 100%.
  • Electrical loads - Any electrical load placed on the vehicle requires energy from the high voltage battery, via the DCDC

Possible Sources

  • Electric Vehicle Supply Equipment (EVSE)
  • Extreme ambient temperatures
  • Cabin temperature preconditioning settings
  • Electrical accessory usage
