CIRCUIT DIAGRAM
(a) Get the value of water temperature with the diagnosis tester
1Connect the diagnosis tester to the diagnosis interface
2Turn the ignition switch to ON
3Read the value of engine water temperature displayed on the diagnosis tester
Standard: The same with the actual engine coolant temperature.
Result and solution:
If it is normal, the water temperature gauge has no malfunction
If abnormal, Inspect the combination meter assembly

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-
tion meter needs replacing when the odometer is abnormal.Condition Standa rd condition

6. INSPECT WATER TEMPERATURE WARNINGLIGHT
(a) Disconnect the water temperature sensor connector.
(b) Turn the ignition ON, the water temperature warning light should go out.
(c) Ground the terminal B5 of the meter connector, the water temperature warning light should light up.
7. INSPECT OIL PRESSURE WARNING LIGHT
(1) Disconnect the oil pressure sensor connector.
(2) Turn the ignition ON, the oil pressure warning light should go out.
(3) Short connector terminal to the ground with a wire, the oil pressure warning light should light up.
8. INSPECT OIL PRESSURE SENSOR
(1) Disconnect the connector from the oil pressure sensor .
(2) Inspect continuity between its terminal and ground.
Engine is stopped: Continuity
Engine runs: No continuity
9. INSPECT PARK BRAKE WARING LIGHT
(1) Disconnect the connector from the park brake switch.
(2) Turn the ignition ON, the park brake warning light should go out.
(3) Short connector terminal to the ground with a wire, the park brake warning light should light up.Standa rd indic ation Re sista nc e (Ω)
