Is the fuse OK?
YES - Reinstall the fuse, and 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 driver's under-dash fuse/relay box.
Is the fuse OK?
YES - Reinstall the fuse, and 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. If the circuit is OK, replace the ABS modulator-control unit.
3. Turn the ignition switch OFF.
4. Disconnect the ABS control unit 31P connector.
5. Measure the voltage between the ABS control unit 31P connector terminal No. 18 and body ground.
Is there battery voltage?
YES - Go to step 6.
NO - Repair open in the wire between the ABS F/S PLY (20A) fuse and the ABS control unit.
6. Turn the ignition switch ON (II).
7. Measure the voltage between the ABS control unit 31P connector terminal No. 15 end body ground.
Is there battery voltage?
YES - Go to step 8.
NO - Repair open in the wire between the R/C MIRROR (7.5A) fuse and the ABS control unit.
8. Turn the ignition switch OFF.
9. Check for continuity between the ABS control unit 31P connector terminal No. 19 and body ground.
Is there continuity?
YES - Go to step 10.
NO - Repair open in the wire between the ABS control unit and body ground (G302).
10. Turn the ignition switch ON (II).
11. 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 12.
12. Remove the gauge assembly, and leave the connectors connected.
13. Connect gauge assembly connector C (14P) terminal No. 14 and body ground with a jumper wires.
Does the ABS indicator go off?
YES - Repair open in the wire between the gauge assembly and the ABS control unites
NO - Check for loose gauge assembly connectors. If the connectors are OK, replace the gauge assembly.
