Pinpoint Test E: No Communication With The Module - Abs Module

WARNING: This page is about a different car, the 2004 Lincoln Town Car. 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.

E1 CHECK CIRCUITS 601 (LB/BK), AND CIRCUIT 88 (BK/WH) FOR AN OPEN

Key in ON position.
Disconnect: ABS Module C135.
Key in ON position.

Measure the voltage between the ABS module C135 pins, harness side and ground as follows:

PIN AND CIRCUIT SPECIFICATION

Pin	Circuit
8	Circuit 88 (BK/WH)
13	Circuit 601 (LB/PK)
14	Circuit 483 (RD)

Are the voltages greater than 10 volts?

Yes

GO to E2.

REPAIR the circuit in question. TEST the system for normal operation.

E2 CHECK CIRCUIT 57 (BK) FOR AN OPEN

Measure the resistance between the ABS module C135 pin 15, circuit 57 (BK), harness side and ground; and between the ABS module C135 pin 12, circuit 57 (BK), harness side and ground.
Are the resistances less than 5 ohms?

Yes

REFER to MULTIFUNCTION ELECTRONIC CONTROL MODULES .

REPAIR the circuit. TEST the system for normal operation.
