Pinpoint Test S: The ESC (Electronic Stability Control) Indicator Is Never Or Always On: Notes

The ESC Indicator Is Never Or Always On 

Normal Operation and Fault Conditions 

If the stability-traction control disabled indicator request is missing or invalid for less than 5 seconds, the IPC defaults the stability-traction control disabled indicator (sliding car OFF 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 disabled indicator request for 5 seconds or longer, the IPC defaults the stability-traction control disabled indicator (sliding car OFF icon) off.

When a MyKey® programmed key is in use and the AdvanceTrac® on feature is configured always on, the traction control system cannot be disabled and the traction control indicator does not turn on when the traction control disable button is pressed. The traction control indicator still functions correctly to indicate a traction control system fault and a traction control active event.
