Checking the Vehicle Speed Signal

Checking The Vehicle Speed Signal







- Ignition off.
- Disconnect the control module.
- Raise the car so that the front wheels are off the ground.

Connect a voltmeter between control module connector terminal 13 and ground.

Then spin the front wheels slowly by hand.

The voltmeter should oscillate between battery voltage and approximately 1.5 V when the wheels are rotated slowly. The voltmeter should oscillate between battery voltage and approximately 6 V when the wheel is rotated quickly.
- 1. The value is OK.
- 2. The voltmeter reads battery voltage constantly.
- 3. The voltmeter reads approximately 0 V constantly.

Select one of the above options.

1 - Checking For Contact Resistance and Oxidation

2 - Checking Components - I

3 - Checking Components - II
