Pinpoint Test 3
PINPOINT TEST 3: ANTI-LOCK BRAKE SYSTEM (ABS) MODULE DOES NOT RESPOND TO THE DIAGNOSTIC TOOLNormal Operation
The ABS module communicates with the WDS or equivalent tester through the international standards organization (ISO) 9141 communication network circuit (LB/W). If circuit (LB/W) becomes open or shorted to ground communications to that module are not possible. Check circuit (LB/W) between the ABS module 0413-102 and the data link connector (DLC) D-01. The total resistance value must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open in circuit (LB/W), damage to the DLC D-01, or damage to the ABS module DLC.
Possible Causes
- ISO 9141 communication network circuit (LB/W) open
- ABS module 0413-102
- ABS module
CAUTION: Use the correct probe adaptor(s) when making measurements. Failure to use the correct probe adaptor(s) may damage the connector.
