Diagnostic 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.

Connector & Terminal: (i10) No. 7 (+) - Chassis Ground (-):

Connector & terminal
(i10) No.7 (+) - Chassis ground (-):

CHECK : 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 (i10) 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.

Connector & Terminal: (i12) No. 8 (+) - Chassis Ground (-):

Connector & terminal
(i12) No.8 (+) - Chassis ground (-):

CHECK : Is the resistance less than 10 ohms?
YES : Go to step 2A3.
NO : Repair harness and connector.

2A3: CHECK TRANSMISSION TYPE

CHECK : Is the transmission type MT?
YES : Go to step 2A4.
NO : Go to step 2A9.

2A4: 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: (B17) No. 1 - (i12) No. 11:

Connector & terminal
(B17) No.1 - (i12) No.11 (-):

CHECK : Is the resistance less than 10 ohms?
YES : Go to step 2A5.
NO : Repair wiring harness.

2A5: CHECK HARNESS CONNECTOR BETWEEN BATTERY AND VEHICLE SPEED SENSOR 2.
1. Turn ignition switch to ON.
2. Measure voltage between vehicle speed sensor 2 connector (B17) and chassis ground.

Connector & Terminal: (B17) No. 3 (+) - Chassis Ground (-):

Connector & terminal
(B17) No.3 (+) - Chassis ground (-):

CHECK : Is the voltage more than 10 V?
YES : Go to step 2A6.
NO : Repair harness connector between battery and vehicle speed sensor 2.

2A6: CHECK HARNESS CONNECTOR BETWEEN VEHICLE SPEED SENSOR 2 AND ENGINE GROUND.
1. Turn ignition switch to OFF.
2. Measure resistance between vehicle speed sensor 2 connector (B17) and engine ground.

Connector & Terminal: (B17) No. 2 (+) - Engine Ground (-):

Connector & terminal
(B17) No.2 (+) - Engine ground (-):

CHECK : Is the resistance less than 10 ohms?
YES : Go to step 2A7.
NO : Repair harness connector between vehicle speed sensor 2 and engine ground.

2A7: 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.
Measure resistance between terminals of vehicle speed sensor 2.

Terminals: No. 2 - No. 3:

Terminals
No.2 - No.3:

CHECK : Is the resistance between 350 and 450 ohms?
YES : Go to step 2A8.
NO : Replace vehicle speed sensor 2.

2A8: CHECK VEHICLE SPEED SENSOR 2.
1. Connect connector to vehicle speed sensor 2.
2. Set the vehicle on free roller, or lift-up the vehicle and support with safety stands.

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

3. Drive the vehicle at speed greater than 20 kph (12 MPH).
4. Measure voltage between vehicle speed sensor 2 connector (B17) and chassis ground.

Connector & Terminals: (B17) No. 1 (+) - Chassis Ground (-):

Connector & terminal
(B17) No.1 (+) - Chassis ground (-):

CHECK : Is the voltage more than 4 V?
YES : Repair or replace speedometer.
NO : Replace vehicle speed sensor 2.

2A9: CHECK HARNESS CONNECTOR BETWEEN COMBINATION METER AND AUTOMATIC TRANSMISSION CONTROL MODULE.
1. Disconnect connector from automatic transmission control module.
2. Measure resistance between combination meter connector (i12) and automatic transmission control module connector (B55).

CAUTION: To measure the voltage and/or resistance, use a tapered pin with a diameter of less than 0.64 mm (0.025 in). Do not insert the pin more than 5 mm (0.20 in).

Connector & Terminal: (i12) No. 11 - (B55) No. 17:

Connector & terminal
(i12) No.11 - (B55) No.17:

CHECK : Is the resistance less than 10 ohms?
YES : Go to step 2A10.
NO : Repair harness connector between combination meter and automatic transmission control module.

2A10: CHECK AUTOMATIC TRANSMISSION CONTROL MODULE.
1. Connect connector to automatic transmission control module.
2. Set the vehicle on tree roller, or lift-up the vehicle and support with safety stands.

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

3. Drive the vehicle faster than 20 kph (12MPH).
4. Measure voltage between automatic transmission control module connector (B55) and chassis ground.

CAUTION: To measure the voltage and/or resistance, use a tapered pin with a diameter of less than 0.64 mm (0.025 in). Do not insert the pin more than 5 mm (0.20 in).
