Combination Meter

DIAGNOSTICS PROCEDURE
If speedometer does not operate, or operates abnormally, check combination meter circuit.

CAUTION: Make sure that trouble code of vehicle speed sensor 2 system appears in electrical system on-board diagnosis.

2A1: CHECK POWER SUPPLY FOR COMBINATION METER




1. Remove combination meter.
2. Turn ignition switch to ON.
3. Measure voltage between combination meter connector and chassis ground.

CHECK : Connector & terminal
(118) No.8 (+) - Chassis ground (-): Is the voltage more than 10 V?

YES : Go to step 2A2.

NO : Repair harness and connector.

NOTE: In this case, repair the following:
- Open circuit in harness between combination meter and battery.
- Poor contact in coupling connectors (i18) and combination meter connector.

2A2: CHECK GROUND CIRCUIT OF COMBINATION METER.




1. Turn ignition switch to OFF.
2. Measure resistance of harness between combination meter connector and chassis ground.

CHECK : Connector & terminal
(i18) No.15 (+) - Chassis ground (-): Is the resistance less than 10 Ohm?

YES : Go to step 2A3.

NO : Repair harness and connector.

2A3: CHECK VEHICLE SPEED SENSOR 2

NOTE:
- If resistance between terminals of vehicle speed sensor 2 is out of specification, the sensor may have a failure.
- If resistance is OK, mechanical trouble may be present in combination meter, speedometer cable and speedometer drive/driven gears in transmission.




1. Remove combination meter.
2. Measure resistance between terminals of combination meter by rotating rotor of speedometer cable hole with screwdriver.

CHECK : Terminals
No.8 - No.15: Is the resistance between 10 Ohm and 1 MOhm (Four times per rotation)?

YES : Repair or replace combination meter.

NO : Replace speedometer.
