Action Taken When the DTC Sets
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Besides storing the DTC as both current and history, the modules on the CAN network each take separate actions as listed:
- Engine control module (ECM)
- Turn ON the MIL during the second consecutive drive cycle with the error detected.
- Record the operating conditions at the time of turning ON the MIL and store the data as Freeze Frame information.
- Transaxle control module (TCM)
Send a request to the ECM to turn ON the MIL during the second consecutive drive cycle with the error detected.
- Electronic brake control module (EBCM)
- The traction control system (TCS) is disabled.
- Turn OFF the TCS LED in the TCS switch.
- The EBCM may also set C0236, C0241, C0276, when a U code is current in the EBCM.
- Body control module (BCM)
- Turn ON the MIL during the second consecutive drive cycle with the error detected.
- Record the operating conditions at the time of turning ON the MIL and store the data as Freeze Frame information.
