NO: Go to step 2.
2. Turn the ignition switch OFF then ON (II) again.
Does the brake system indicator come on?
YES: Go to step 3.
NO: Repair open in the indicator power source circuit
^ Blown No.10 (7.5A) fuse in the under-hood fuse/ relay box.
^ Open in the wire between the No.10 (7.5A) fuse and the gauge assembly.
^ Open in the circuit inside the fuse box.
3. Turn the ignition switch OFF.
4. Disconnect the ABS 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 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 model).
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 model) and body ground.
'02-04 models:
'05 model:
Is there continuity?
YES: Repair short to body ground in the wire between the gauge assembly and the ABS 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 model: 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 model: Check for continuity between the gauge assembly connector A (16P) terminal No. 15 and body ground.

'05 model
Is there continuity?
YES: Check for loose terminals in the gauge assembly connectors. If the connector is OK, replace the gauge assembly.
