PINPOINT TEST J : DTC U3003:17

Refer to Wiring Diagrams Cell 120 for schematic and connector information.

Normal Operation and Fault Conditions

REFER to: Third Row Seats - System Operation and Component Description (501-10C Third Row Seats, Description and Operation).

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
SCMJ U3003:17 Battery Voltage: Circuit Voltage Above Threshold Set by the SCMJ whenever battery voltage has been greater than 16.5 volts for 5 seconds or more.

Possible Sources

  • Charging system concern
  • Wiring, terminals or connectors
  • SCMJ
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
J1 RETRIEVE ALL CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS) IN ALL MODULES
  • Ignition ON.
  • Using a diagnostic scan tool, retrieve ALL Continuous Memory Diagnostic Trouble Codes (CMDTCs).

Is DTC B1317, B1318, B1676, U3003:16 or U3003:17 present in one or more modules AND are any charging system Diagnostic Trouble Codes (DTCs) present in the PCM?
Yes DIAGNOSE the charging system. Refer to the appropriate section in Group 414 for the procedure.
No GO to J2

J2 TEST BATTERY CONDITION
  • Ignition OFF.
  • Carry out the Battery Condition Test.
    REFER to: Battery (414-01 Battery, Mounting and Cables, Diagnosis and Testing).

Did the battery pass the condition test?
Yes If the battery passed the condition test but required a recharge, DIAGNOSE the charging system.
REFER to: Charging System (414-00 Charging System - General Information, Diagnosis and Testing).
CLEAR all Continuous Memory Diagnostic Codes (CMDTCs).
If the battery passed the condition test and did not require a recharge, GO to J3
No INSTALL a new battery.
REFER to: Battery (414-01 Battery, Mounting and Cables, Removal and Installation).
CLEAR all Continuous Memory Diagnostic Codes (CMDTCs).

J3 CHECK THE CHARGING SYSTEM VOLTAGE
  • Start the engine.
  • Measure the voltage of the battery.
  • Turn off all accessories while measuring the battery voltage.

Is the voltage between 13 and 15.2 volts?
Yes GO to J4
No DIAGNOSE the charging system. Refer to the appropriate section in Group 414 for the procedure. CLEAR all Continuous Memory Diagnostic Codes (CMDTCs).

J4 CHECK THE SCMJ (POWER FOLD SEAT MODULE) OPERATION
  • Ignition OFF.
  • Disconnect and inspect the SCMJ connectors.
  • Repair:
    • corrosion (install new connector or terminals - clean module pins)
    • damaged or bent pins - install new terminals/pins as necessary
    • pushed-out pins - install new pins as necessary
  • Reconnect the SCMJ connectors. Make sure they seat and latch correctly.
  • Reconnect all previously disconnected connectors.
  • Ignition ON.
  • Operate the system and determine if the concern is still present.

Is the concern still present?
Yes 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 SCMJ.
REFER to: Power Fold Seat Module [SCMJ] (501-10C Third Row Seats, Removal and Installation).
TEST the system for normal operation.
No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
