Instrument Cluster / Carrier: Testing and Inspection

Combination Meter

DIAGNOSTICS PROCEDURE

Step 1 - 4:

If speedometer does not operate, or operates abnormally, check combination meter circuit (shown in flow chart as described).

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

1. CHECK POWER SUPPLY FOR COMBINATION METER.




1. Remove combination meter.
2. Turn ignition switch to ON.
3. Measure voltage at combination meter connector terminal.

Connector & terminal / Specified voltage:
(114) No.11 - Body / 10 V, or more

2. CHECK GROUND CIRCUIT OF COMBINATION METER.




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

Connector & terminal / Specified voltage:
(112) No.1 - Body / 10 Ohm, max.

3. CHECK HARNESS CONNECTOR BETWEEN COMBINATION METER AND VEHICLE SPEED SENSOR 2.




1. Disconnect connector from vehicle speed sensor 2.
2. Measure resistance of harness connector between vehicle speed sensor 2 and combination meter.

Connector & terminal / Specified resistance:
(B17) No.1 - (i11) No.2 / 10 Ohm, max.
(B17) No.2 - (i11) No.3 / 10 Ohm, max.

4. 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 and voltage between terminals of vehicle speed sensor 2 is out of specification, mechanical trouble may be present between vehicle speed sensor 2 and speedometer shaft in transmission.




1. Disconnect connector from vehicle speed sensor 2.
2. Measure resistance between terminals of vehicle speed sensor 2.

Terminals / Specified resistance:
No.1 - No.2 / 350 - 450 Ohm

WARNING: Be careful not to be caught up by the running wheels.




3. Set the vehicle on free roller, or lift-up the vehicle and support with safety stands.
4. Drive the vehicle at speed greater than 20 km/h (12 MPH).
5. Measure voltage between terminals of vehicle speed sensor 2.

Terminals / Specified voltage:
No.1 - No.2 / 5 V, mm. (AC range)







- Using an oscilloscope:
1. Turn ignition switch to OFF.
2. Set oscilloscope to vehicle speed sensor 2.
3. Drive the vehicle at speed greater than 20 km/h (12 MPH).
4. Measure signal voltage.
Specified voltage (V): 5 V, mm
