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
