Stability System Disabled Indicator Always On
Stability System Disabled Indicator Always On
Circuit Description
The stability system disable indicator is controlled by the instrument cluster via class 2 serial data messages from the electronic brake control module (EBCM). When the instrument cluster sees a class 2 message from the EBCM that tells the instrument panel cluster (IPC) that the stability system is malfunctioning, the EBCM then disables vehicle stability enhancement system (VSES) and traction control system (TCS) and sends a message to the instrument cluster to turn the stability system disable indicator always on and TCS indicators ON. Each time the ignition is cycled from OFF to ON, the VSES is enabled:
The following conditions will cause the VSES/TCS indicators to illuminate:
* The EBCM has disabled the VSES/TCS due to a DTC.
* The instrument cluster bulb check-When the ignition switch is turned to ON, the VSES/TCS indicators will turn ON for approximately 3 seconds and then turn OFF.
