Pinpoint Test A: No Communication With The Anti-Lock Brake System (Abs) Module
WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
The Flex Probe Kit must be used for all test connections. Use of standard multimeter probes may damage wiring terminals
- A1 CHECK THE ABS MODULE VOLTAGE SUPPLY CIRCUITS FOR AN OPEN
- Key in OFF position.
- Disconnect: ABS Module C135.
- Key in ON position.
- Measure the voltage between ground and:
- ABS module C135-1, SBB36 (GN/RD), harness side.
- ABS module C135-8, CBP19 (BN/WH), harness side.
- ABS module C135-32, SBB10 (YE/RD), harness side.
- Are the voltages greater than 10 volts?
Yes : GO to A2.
No : VERIFY SJB fuse 28 (10A) is OK. If OK, REPAIR circuit CBP19 (BN/WH) for an open.
VERIFY BJB fuse 36 (40A) is OK. If OK, REPAIR circuit SBB36 (GN/RD) for an open.
VERIFY BJB fuse 10 (20A) is OK. If OK, REPAIR circuit SBB10 (YE/RD) for an open.
TEST the system for normal operation.
- A2 CHECK THE ABS MODULE GROUND CIRCUIT FOR AN OPEN
- Key in OFF position.
- Measure the resistance between ABS module C135-16, circuit GD123 (BK/GY), harness side and ground.
- Is the resistance less than 5 ohms?
Yes : REFER to MODULE COMMUNICATIONS NETWORK to continue diagnosis of the communication network.
No : REPAIR circuit GD123 (BK/GY) for an open. TEST the system for normal operation.
