Test F: Entire Combination Meter Does Not Operate

1. Inspect the continuity in the ECU-B fuse, the GAUGE 1 fuse and the IG2 fuse. See Fig 1. If the continuity is OK, go to the next step. If the continuity is not OK, replace the fuse.
2. Check the combination meter assembly (power source circuit):
   • Check the voltage. Disconnect the C7 connector from the combination meter assembly. See Figure. Measure the voltage (10-14 volts) between terminal No. C7-20 of the combination meter assembly connector and body ground. Turn the ignition switch to ON. Measure the voltage (10-14 volts) between terminal No. C7-39 of the combination meter assembly connector and body ground. Turn the ignition switch to ON. Measure the voltage (10-14 volts) between terminal No. C7-40 of the combination meter assembly connector and body ground.
   • If the voltage is OK, go to the next step. If the voltage is not OK, repair or replace the wiring harness or connector.
3. Check the combination meter assembly (ground circuit):
   • Check continuity. Disconnect the C7 connector from the combination meter assembly. See Figure. Check that continuity exists between terminal No. C7-1 of the combination meter connector and body ground. Check that continuity exists between terminal No. C7-21 of the combination meter assembly connector and body ground.
   • If the continuity is OK, check and replace the combination meter assembly. See COMBINATION METER SAFETY PAD SUB-ASSEMBLY  under REMOVAL & INSTALLATION. If continuity is not OK, repair or replace the harness or connector.
