ABS Indicator Does Not Go Off
ABS indicator does not go off1. Check the ABS F/S RLY (20A) fuse in the under-hood multi fuse 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 this fuse circuit. If the circuit is OK, replace the ABS modulator-control unites
2. Check the R/C MIRROR (7.5A) 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 this fuse circuit.
3. Disconnect the ABS control unit 31P connector.
4. Measure the voltage between terminal No. 18 and body ground.
Is there battery voltage?
YES - Go to step 5.
NO - Repair open in the wire between the ABS F/S RLY (20A) fuse and the ABS control unit.
5. Turn the ignition switch ON (II).
6. Measure the voltage between the ABS control unit 31P connector terminal No. 15 and body ground.
Is there battery voltage?
YES - Go to step 7.
NO - Repair open in the wire between the No. 16 (7.5A) fuse and the ABS control units
7. Turn the ignition switch OFF.
8. Check for continuity between the ABS control unit 31P connector terminal No. 19 and body ground.
Is there continuity?
YES - Go to step 9.
NO - Repair open in the wire between the ABS control unit and body ground (G301).
9. Turn the ignition switch ON (II).
10. Connect the ABS control unit 31P connector terminal No. 13 and body ground with a jumper wire.
Does the ABS indicator go off?
YES - Check for loose terminals in the ABS control unit 31P connector. If necessary, substitute a known-good ABS modulator-control unit, and recheck.
NO - Go to step 11.
11. Connect gauge assembly connector B (18P) terminal No. 16 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 control unit.
NO - Check for loose gauge assembly connector B (18P). If the connector is OK, replace the printed circuit board in the gauge assembly.
