Pinpoint Test X: Control Module Improper Wake-Up Performance
- Normal Operation and Fault Conditions
The ABS module continually monitors the brake system for potential system concerns. During module wake up, several items are monitored and certain operations are expected to be performed. If one or more of these do not occur as expected, the ABS module sets a DTC and requests the illumination of the ABS warning indicator.
