Preliminary diagnosis

(1) If the indicator lamps operate, but none of the gauges operate, go to Step 2. If all of the gauges and the CCD data bus message-controlled indicator lamps are inoperative, go to Step 5.

(2) Check the fused B(+) fuse in the junction block.

If OK, go to Step 3. If not OK, repair the shorted circuit or component as required and replace the faulty fuse.

(3) Check for battery voltage at the fused B(+) fuse in the junction block. If OK, go to Step 4. If not OK, repair the open fused B(+) circuit to the battery as required.

(4) Disconnect and isolate the battery negative cable. Remove the instrument cluster. Connect the battery negative cable. Check for battery voltage at the fused B(+) circuit cavity of the instrument cluster wire harness connector A. If OK, refer to Instrument Cluster - Self-Diagnostic Test in the Diagnosis and Testing section of this group. If not OK, repair the open fused B(+) circuit to the fuse in the junction block as required.

(5) Check the fused ignition switch output (run/ start) fuse in the junction block. If OK, go to Step 6.

If not OK, repair the shorted circuit or component as required and replace the faulty fuse.

(6) Turn the ignition switch to the On position and check for battery voltage at the fused ignition switch output (run/start) fuse in the junction block. If OK, go to Step 7. If not OK, repair the open fused ignition switch output (run/start) circuit to the ignition switch as required.

(7) Turn the ignition switch to the Off position.

Disconnect and isolate the battery negative cable.

Install the instrument cluster. Connect the battery negative cable. Turn the ignition switch to the On position. Set the park brake. The red brake warning lamp should light. If OK, go to Step 8. If not OK, go to Step 9.

(8) Turn the ignition switch to the Off position.

Turn on the park lamps and adjust the panel lamps dimmer thumbwheel on the headlamp switch to the full bright position. The cluster illumination lamps should light. If OK, go to Step 10. If not OK, repair the open power ground circuit from the instrument cluster wire harness connector A to ground as required.

(9) Turn the ignition switch to the Off position.

Disconnect and isolate the battery negative cable.

Remove the instrument cluster. Connect the battery negative cable. Turn the ignition switch to the On position. Check for battery voltage at the fused ignition switch output (run/start) circuit cavity of the instrument cluster wire harness connector A. If OK, refer to Instrument Cluster - Self-Diagnostic Test in the Diagnosis and Testing section of this group. If not OK, repair the open fused ignition switch output (run/start) circuit to the fuse in the junction block as required.

(10) Disconnect and isolate the battery negative cable. Remove the instrument cluster. Check for continuity between the logic ground circuit cavity of the instrument cluster wire harness connector A and a good ground. There should be continuity. If OK, refer to Instrument Cluster - Self-Diagnostic Test in the Diagnosis and Testing section of this group. If not OK, repair the open logic ground circuit to ground as required.
