1994 Lincoln Town Car anti-lock light on

There is a malfunction somewhere in the anti-lock brake system. Your normal mechanical brakes will still work, but the anti-skid (ABS) will not.

Codes need to be pulled from it's computer and then diagnosed. See procedure below

The anti-lock brake/traction assist system has on-board capabilities. However, the anti-lock brake control module as received from manufacturing is equipped with a stored error code (61). This will affect the service procedure.

The DTCs can be retrieved from the anti-lock brake control module in the following manner.

1. Connect SUPER STAR II tester to data link connector located in engine compartment.
2. Place tester.
3. Turn on SUPER STAR II tester and latch button down in TEST position.
4. Turn ignition switch to RUN position.
5. Read first DTC output. After approximately 15 seconds the next DTC will be output. Leave button latched until all DTCs are output.

NOTE: Make sure that all DTCs are written down.

The diagnostic procedure should be as follows providing that the CHECK ANTI-LOCK BRAKE indicator stays on all the time or flashes intermittently.

NOTE: If the BRAKE warning indicator is on or intermittently comes on, refer to the warning indicator symptom chart as outlined.

1. If the first DTC received is 18, 19 or in the 20s and no other DTC is received, service the indicated component. No other DTCs can be output if a 18, 19 or 20s DTC exists. After servicing the indicated 18, 19 or 20s DTC, repeat the procedure for retrieving DTCs.

NOTE: If there are more DTCs stored in the anti-lock brake control module memory, no DTCs will erase until all DTCs have been output by the SUPER STAR II tester, all malfunctions have been serviced and the vehicle is driven about 40 km/h (25 mph). This means that if an 18, 19 or 20s DTC originally existed and was serviced, it can be ignored when running the on-board diagnostic the second time.

2. If a Code 61 is received with any other DTC, ignore the Code 61 and service the other indicated malfunctions. If after correcting all other indicated malfunctions, the CHECK ANTI-LOCK BRAKE indicator is still on, service the FLS circuit.
3. If a Code 61 is received and no other DTCs are received, service the FLS circuit.
4. If no DTC, or only a Code 10 is received, use the Anti-Lock Quick Check Sheet since some possibilities are not recognized and retained in the anti-lock brake control module memory.
