Test L: The ABS Warning Indicator Is Never/Always On
PINPOINT TEST L: THE ABS WARNING INDICATOR IS NEVER/ALWAYS ONNormal Operation
The ABS module provides the ABS status to the instrument cluster (IC) over the high speed controller area network (HS-CAN) communication bus. If a fault condition exists in the ABS, the ABS module sends the instrument cluster (IC) a command to either flash the ABS warning indicator or to turn it on. If the ABS status message is missing for less than 5 seconds, the ABS warning indicator remains in the last indication mode (on or off). If the ABS status message is missing for more than 5 seconds, the instrument cluster (IC) sets DTC U0121 and defaults the ABS warning indicator on.
This pinpoint test is intended to diagnose the following:
- ABS module
- Instrument cluster (IC)
