Test K: The ABS Warning Indicator Is Always On

PINPOINT TEST K: THE ABS WARNING INDICATOR IS ALWAYS ON

Normal Operation
The instrument cluster (IC) receives the ABS status from the ABS module through hardwired circuitry. When an ABS concern is present, the ABS module sends the instrument cluster (IC) a command to illuminate the ABS warning indicator. If the instrument cluster (IC) detects a fault condition in the ABS, the instrument cluster (IC) turns on the ABS warning indicator.

- DTC C1221 (ABS Warning Lamp Output Circuit Short to Ground) - sets if circuit CCA01 (BU/OG) becomes shorted to ground and the instrument cluster (IC) defaults the ABS warning indicator on.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- ABS module
- Instrument cluster (IC)
