PINPOINT TEST B: THE ABS MODULE DOES NOT RESPOND TO THE SCAN TOOL
Normal Operation
The ABS module communicates with the scan tool through the high speed controller area network (HS-CAN). Circuits 1827 (WH/LG) (HS-CAN +)
and 1828 (PK/LG) (HS-CAN -) provide the network connection to the ABS module. The ABS module shares the HS-CAN with the PCM and the
instrument cluster (IC). Voltage for the ABS module is provided by circuits 601 (LB/PK) and 1844 (LG/RD). Both circuits 1205 (BK) provide
ground.
