Pinpoint Test Aa: The Stability-Traction Control Indicator (Sliding Car Icon) Is Never Or Always On
- Normal Operation and Fault Conditions
See Stability-Traction Control Indicator (Sliding Car Icon). REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
If the stability-traction control indicator request is missing or invalid for less than 5 seconds, the IPC defaults the stability-traction control indicator (sliding car icon) to the last indication state (on or off), based upon the last message received.
If the IPC does not receive the stability-traction control indicator request for 5 seconds or longer, the IPC defaults the stability-traction control indicator (sliding car icon) on.

Yes REFER to: Communications Network No GO to AA4 - AA4 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) INDICATOR LAMP CONTROL ACTIVE COMMAND USING A DIAGNOSTIC SCAN TOOL
- Using a diagnostic scan tool, view the IPC Parameter Identifications (PIDs).
- Select the IPC stability-traction control indicator (TC/IVD/RSCLMP) PID.
- Command the stability-traction control indicator (sliding car icon) on and off while observing the stability-traction control indicator (sliding car icon).
Does the stability-traction control indicator (sliding car icon) illuminate when commanded on and turn off when commanded off?
Yes If the stability-traction control indicator (sliding car icon) is never on, the system is operating correctly. If the stability-traction control indicator (sliding car icon) is always on, INSTALL a new ABS module. REFER to: Anti-Lock Brake System (ABS) Module No INSTALL a new IPC.
