C1275

CIRCUIT DESCRIPTION
The PCM monitors various parameters. The PCM will not allow operation of the Enhanced Traction system (ETS) if any PCM parameter falls below a predetermined value.

CONDITIONS FOR SETTING THE DTC
When a malfunction is detected by the PCM, the PCM causes the ETS to shutdown until the malfunction is corrected.

ACTION TAKEN WHEN THE DTC SETS
This DTC is a temporary operational malfunction.
The following actions are taken when the DTC sets:
^ A malfunction DTC is stored.
^ The ETS is disabled.
^ The TRAC OFF indicator is turned ON.

The ABS remains functional.
If the ETS is no longer inhibited, the indicator lamp will be turned OFF but the DTC will still be stored.

CONDITIONS FOR CLEARING THE DTC
ETS will remain disabled until the EBTCM receives a traction allowed message from the PCM. When the EBTCM receives this message, it re-enables the ETS and turns OFF the TRAC OFF indicator.

DIAGNOSTIC AIDS
Check for PCM DTCs. If no PCM DTC is stored, DTC C1275 may have set due to a hot engine or a hot transaxle (both normal conditions). No repairs should be made to the ETS System.
Perform a thorough inspection of the wiring and the connectors.
Failure to carefully inspect wiring may result in a misdiagnosis. A misdiagnosis may result in replacing parts without repairing the malfunction.
