Brief Description of DTC
Internal fuel injection pump failure. Low power, engine
derated, or engine stops.
A Companion DTC was set in both the ECM and PCM.
A fault has been generated in the companion engine
control module.
A Companion DTC was set in both the ECM and PCM.
No CCD/J1850 messages received from the powertrain
control module-Aisin transmission
Bus communication failure to PCM.
No CCD/J1850 messages received from the body control
Unsuccessful attempt to write to an EEPROM location by
the control module.
Unsuccessful attempt to update Service Reminder
Indicator (SRI or EMR) mileage in the control module
No CCD/J1850 messages received from the electronic
transmission control module (EATX) or the Aisin
