^ Blown No. 10 (7.5 A) fuse in the under-dash fuse/relay box.
^ Open in the wire between the No. 10 (7.5 A) fuse and the gauge assembly.
^ Open in the circuit inside the fuse box.
3. Turn the ignition switch OFF.
4. Disconnect the ABS modulator-control unit 25P connector.
5. Turn the ignition switch ON (II).
Does the ABS indicator come on?
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 6.
6. Turn the ignition switch OFF.
7. Remove the gauge assembly.
8. Disconnect the gauge assembly connector A (22P) ('02-04 models) or gauge assembly connector B (20P) ('05-06 models).
9. Check for continuity between 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.
Is there continuity?
YES - Repair short to body ground in the wire between the gauge assembly and the ABS modulator-control unit.
NO - Go to step 10.
10. '02-04 models: Connect the gauge assembly connector A (22P), and disconnect the gauge assembly connector B (18P).
'05-06 models: Connect the gauge assembly connector B (20P), and disconnect the gauge assembly connector A (16P).
11. '02-04 models: Check for continuity between the gauge assembly connector B (18P) terminal No. 18 and body ground.
'05-06 models: Check for continuity between the gauge assembly connector A (16P) terminal No. 15 and body ground.
Is there continuity?
YES - Check for loose terminals in the gauge assembly connectors. If the connector is OK, replace the gauge assembly.
NO - Repair open in the wire between the gauge assembly and body ground (G401).
