ABS Indicator Does Not Go Off and No DTCs Are Stored
ABS indicator does not go off, and no DTCs are stored1. Check the No. 8 (20 A) fuse in the under-hood fuse/relay box, and reinstall the fuse if it is OK.
Is the fuse OK?
YES - Go to step 2.
NO - Replace the fuse, and recheck. If the fuse is blown, check for a short to body ground in the fuse circuit. If the circuit is OK, replace the ABS modulator-control unit.
2. Check the No. 11 (7.5 A) fuse in the under-dash fuse/relay box, and reinstall the fuse if it is OK.
Is the fuse, OK?
YES - Go to step 3.
NO - Replace the fuse, and recheck. If the fuse is blown, check for a short to body ground in the fuse circuit.
3. Disconnect the ABS modulator-control unit 25P connector.
4. Measure the voltage between the ABS modulator-control unit 25P connector terminal No. 8 and body ground.
Is there battery voltage?
YES - Go to step 5.
NO - Repair open in the wire between the No. 8 (20 A) fuse and the ABS modulator-control unit.
5. Turn the ignition switch ON (II).
6. Measure the voltage between the ABS modulator-control unit 25P connector terminal No. 16 and body ground.
Is there battery voltage?
YES - Go to step 7.
NO - Repair open in the wire between the No. 11 (7.5 A) fuse and the ABS modulator-control unit.
7. Turn the ignition switch OFF.
8. Check for continuity between the ABS modulator-control unit 25P connector terminal No. 24 and body ground.
Is there continuity?
YES - Go to step 9.
NO - Repair open in the wire between the ABS modulator-control unit and body ground (G202).
9. Turn the ignition switch ON (II).
10. Connect the ABS modulator-control unit 25P connector terminal No. 7 and body ground with a jumper wire.
Does the ABS indicator go off?
YES - Check for loose terminals in the ABS modulator-control unit 25P connector. If necessary, substitute a known-good ABS modulator-control unit, and recheck.
NO - Go to step 11.
11. Connect the gauge assembly connector A (22P) terminal No. 14 ('02-04 models) or gauge assembly connector B (20P) terminal No. 12 ('05-06 models) and body ground with a jumper wire.
Does the ABS indicator go off?
YES - Repair open in the wire between the gauge assembly and the ABS modulator-control unit.
NO - Check for loose gauge assembly connectors. If the connector is OK, replace the gauge assembly.
