PINPOINT TEST 2: THE ANTI-LOCK BRAKE SYSTEM (ABS) CONTROL MODULE DOES NOT RESPOND TO THE SCAN TOOL - HYBRID

Normal Operation

The ABS control module communicates with the scan tool through the high speed controller area network (HS-CAN). Circuits (W/L) (HS-CAN +) and (W) (HS-CAN -) provide the network connection to the ABS control module. The ABS control module shares the HS-CAN network with the PCM, the instrument cluster, the restraints control module (RCM), the power steering control module, the transmission control module, the traction battery control module (TBCM) and the occupant classification sensor module. Voltage for the ABS control module is provided by circuits (V/BR), (BR/R), (R) and (Y/R). Ground is provided by circuit (B/Y) and (B/V).

Possible Causes
- Fuse
- Wiring, terminals or connectors
- ABS control module

Diagnostic Procedure
