DETECT MALFUNCTIONING PART

Check the following.

●

Harness connectors M67, C1

●

Harness for open or short between fuel level sensor unit and ground

>> Repair open circuit or short to power in harness or connectors.

5. 

CHECK FUEL LEVEL SENSOR INPUT CIRCUIT FOR OPEN AND SHORT

1.

Disconnect ECM harness connector.

2.

Check harness continuity between ECM terminal 46 and fuel level sensor unit terminal G. Refer to Wiring
Diagram.

3.

Also check harness for short to ground and short to power.

OK or NG

OK

Component Description

UBS00DM6

The vehicle speed sensor is installed in the transmission. It contains
a pulse generator which provides a vehicle speed signal to the
speedometer. The speedometer then sends a signal to the ECM.

On Board Diagnosis Logic

UBS00DM7

DTC Confirmation Procedure

UBS00DM8

CAUTION:

Always drive vehicle at a safe speed.

NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 5 seconds before conducting the next test.
TESTING CONDITION:
Steps 1 and 2 may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a
road test is expected to be easier, it is unnecessary to lift the vehicle.

 WITH CONSULT-II

1.

Start engine.

2.

Read “VHCL SPEED SE” in “DATA MONITOR” mode with CON-
SULT-II. The vehicle speed on CONSULT-II should exceed 10
km/h (6 MPH) when rotating wheels with suitable gear position.
If NG, go to 

EC-983, "Diagnostic Procedure"

 .

If OK, go to following step.

3.

Select “DATA MONITOR” mode with CONSULT-II.

4.

Warm engine up to normal operating temperature.

5.

Maintain the following conditions for at least 60 consecutive sec-
onds.

6.

If 1st trip DTC is detected, go to 

EC-983, "Diagnostic Procedure"

 .

Overall Function Check

UBS00DM9

Use this procedure to check the overall function of the vehicle speed sensor circuit. During this check, a 1st
trip DTC might not be confirmed.

 WITH GST

1.

Lift up drive wheels.

2.

Start engine.

3.

Read vehicle speed sensor signal in MODE 1 with GST.
The vehicle speed sensor on GST should be able to exceed 10 km/h (6 MPH) when rotating wheels with
suitable gear position.
