5. FUEL GAUGE MALFUNCTION

CIRCUIT DIAGRAM

(a) Inspect the combination meter assembly

1

Inspect resistance

Remove the combination meter assembly and disconnect connectors

Inspect continuity between terminals

Standard:

Result and solution:

Normal Replace the combination meter assembly

If abnormal inspect the fuel level sensor

2

Inspect the fuel level sensor

Result and solution:

Normal: Repair or replace the harness and connector

If abnormal replace the fuel level sensor

6. THE OTHER INDICATORS

Short the ports of the other indicators respectively to the ground or power source in accordance with the

Circuit Diagram, the indicators will light correspondingly. If it dose not light, replace the combination meter.

If it lights, repair or replace the harness or connector.

7. ODOMETER MALFUNCTION

Inspect first supposing the problem to be from the speedometer. If the speedometer is normal, the combina-
