ABS Indicator Does Not GO Off, and No DTCS Are Stored

ABS indicator does not go off, and no DTCs are stored
1. Check the No. 14 (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. 16 (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. If the circuit is OK, replace the ABS modulator-control unit.
3. Disconnect the gauge assembly 22P connector.





4. Measure the voltage between terminal No. 8 and body ground.
Is there battery voltage?
YES-Go to step 5.
NO-Repair open in the wire between the No. 14 (20 A) fuse and the ABS modulator-control unit.
5. Turn the ignition switch ON (II).





6. Measure the voltage between the ABS 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. 16 (7.5 A) fuse and the ABS modulator-control unit.
7. Turn the ignition switch OFF.
8. Reconnect the ABS control unit 25P connector.
9. Turn the ignition switch ON (II).





10. Measure the voltage between the ABS control unit 25P connector terminal No. 24 and body ground.
Is there less than 0.3 V?
YES-Go to step 11.
NO-Repair open in the wire between the ABS modulator-control unit and body ground (G201).
11. Turn the ignition switch OFF, disconnect the ABS control unit 25P connector.
12. Turn the ignition switch ON (II).





13. Connect the ABS 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 control unit 25P connector. If necessary, substitute a known-good ABS modulator-control unit, and recheck.
NO- Go to step 14.
14. Turn the ignition switch OFF, reconnect the gauge assembly 22P connector.
15. Connect the gauge assembly 22P connector terminal No. 15 and body ground with a jumper wire.





16. Turn the ignition switch ON (II).
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 22P connector. If the connector is OK, replace the gauge assembly.
