Pinpoint Test 3
PINPOINT TEST 3: THE ANTI-LOCK BRAKE SYSTEM (ABS) MODULE DOES NOT RESPOND TO THE DIAGNOSTIC TOOLStep 1 - 2:
Normal Operation
The ABS module communicates with the diagnostic tool through the high speed CAN communications network, circuits (W) and (B). If one of the bus wires becomes shorted to ground or voltage, communications can continue at a reduced level. Check circuits (W) and (B) between the ABS module 0413-101 and the DLC D-01. Total resistance values must not be more than 5 Ohms. If the resistance is more than 5 Ohms there is an open in one of the high speed CAN circuits, damage to the DLC damage to the ABS module 0413-101, or a problem in an in-line connector.
Possible Causes
- high speed CAN circuits 1908 (W) and 1909 (B) shorted to ground or open
- DLC D-01
- 0413-101
- ABS Module
