Pinpoint Tests


PINPOINT TEST RA : PARTICULATE FILTER SYSTEM

  WARNING: Manual regeneration of the particulate filter causes the exhaust gas to quickly get very hot. Initiate a manual regeneration only when the vehicle is on the ground with the area around the tailpipe free of people, obstructions, foreign material or other items. Failure to follow these instructions may result in serious personal injury.

NOTE: Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.

Normal Operation and Fault Conditions

Refer to the DTC Fault Trigger Conditions.

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
PCM P226D:00 Particulate Filter Deteriorated/Missing Substrate Bank 1: No Sub Type Information Sets when the PCM detects the particulate filter pressure to be lower than an expected threshold.
PCM P226E:00 Particulate Filter Deteriorated/Missing Substrate Bank 2: No Sub Type Information Sets when the PCM detects the particulate filter pressure to be lower than an expected threshold.
PCM P242F:00 Particulate Filter Restriction - Ash Accumulation (Bank 1): No Sub Type Information Sets when the PCM detects the particulate filter pressure to be higher than an expected threshold.
PCM P243A:00 Particulate Filter Restriction - Ash Accumulation (Bank 2): No Sub Type Information Sets when the PCM detects the particulate filter pressure to be higher than an expected threshold.
PCM P243B:00 Particulate Filter Restriction - Forced Limited Power (Bank 2): No Sub Type Information Sets when the PCM detects the particulate filter pressure is greater than a calibrated amount during normal. The PCM monitors the particulate filter for a high restriction. The presence of this DTC may indicate that the vehicle is operating in derate mode and may experience a loss of power. After repair, the vehicle may still display a system warning message. Drive the vehicle until the system warning message has cleared from the instrument cluster message center. Excessive amount of soot or ash in the particulate filter may be caused by extended engine idle operation after the DRIVE TO CLEAN EXHAUST message is displayed in the message center. Refer to the Owner Literature for additional information on the message center DRIVE TO CLEAN EXHAUST message. Check for other Diagnostic Trouble Codes (DTCs).
