1. Spray the suspected area with a 5 percent saltwater solution. To create a 5 percent saltwater solution, add 2 teaspoons of salt to 8 fl oz of

water (10 g of salt to 200 ml of water).

2. Test drive the vehicle over various road surfaces: bumps, turns, etc., above 40 km/h (25 mph) for at least 30 seconds.

3. Rinse the area thoroughly when completed.

Circuit/System Verification

Observe the scan tool Wheel Speed Sensor parameter. The reading should be the same speed on all sensors when driving in a straight line at a

speed greater than 20 km/h (13 mph).

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the EBCM.

2. Ignition ON, test for less than 1 V between the 12 V reference circuit terminal of the appropriate sensor listed below and ground.

* Left front sensor circuit terminal 28

* Right front sensor circuit terminal 17

* Left rear sensor circuit terminal 4

* Right rear sensor circuit terminal 3

瀚慖f greater than the specified range, test the 12 V reference circuit for a short to voltage.

3. Test for less than 1 V between the signal circuit terminal of the appropriate sensor listed below and ground.

* Left front sensor circuit terminal 29

* Right front sensor circuit terminal 6

* Left rear sensor circuit terminal 5

* Right rear sensor circuit terminal 2

瀚慖f greater than the specified range, test the signal circuit for a short to voltage.

4. Ignition OFF, test for infinite resistance between the 12 V reference terminal of the appropriate sensor circuit listed below and ground.

* Left front sensor circuit terminal 28

* Right front sensor circuit terminal 17

* Left rear sensor circuit terminal 4

* Right rear sensor circuit terminal 3

瀚慖f less than the specified value, test the 12 V reference circuit for a short to ground.

5. Test for infinite resistance between the following signal circuit terminal of the appropriate sensor circuit listed below and ground.

* Left front sensor circuit terminal 29
