1999-2002 CHEVROLET SILVERADO 2000-2002 CHEVROLET TAHOE, SUBURBAN 2002 CHEVROLET AVALANCHE 1999-2002 GMC SIERRA 2000-2002 GMC YUKON, YUKON XL LOCATED IN THE SEVERE CORROSION AREAS LISTED BELOW Service Procedure The following procedure provides instructions for repairing a corrosion condition where the front wheel speed sensor mounts on the front wheel bearing assembly. 1. Raise the vehicle on a suitable hoist and support as necessary. 2. Remove both front tires and wheels. 3. Compress the front brake caliper pistons. 3.1. Install a large C-clamp over the top of the caliper housing and against the back of the outboard pad. 3.2. Slowly tighten the C-clamp until the pistons are pushed completely into the caliper bores. 3.3. Remove the C-clamp from the caliper. Important: It is not necessary to remove the front brake caliper from the bracket when removing the bracket in the next step. 4. Remove the two bolts that attach the front brake caliper mounting brackets to the knuckle. Notice: Support the brake caliper with heavy mechanic’s wire, or equivalent, whenever it is separated from its mount, and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak. 5. Remove the brake caliper and bracket as an assembly and support it with heavy mechanic’s wire or equivalent. DO NOT disconnect the hydraulic brake flexible hose from the caliper. 6. Mark the relationship of the rotor to the bearing hub. 7. If equipped, remove the rotor retaining push nuts from the wheel studs

Action Taken When the DTC Sets Conditions for Clearing the MIL/DTC Diagnostic Aids Test Description The numbers below refer to the step numbers on the diagnostic table. 2. This step verifies that the PCM is receiving a signal from the vehicle speed sensor. 3. This step verifies that there are no opens in the circuitry from the vehicle speed sensor to the PCM connector. 7. This step performs a resistance test on the VSS circuits from the PCM connector. • The transmission defaults to 3rd gear. • The PCM inhibits TCC operation. • The PCM illuminates the Malfunction Indicator Lamp (MIL). • The PCM turns OFF the MIL after three consecutive ignition cycles without a failure reported. • A scan tool can clear the DTC from the PCM history. The PCM clears the DTC from the PCM history if the vehicle completes 40 warm-up cycles without a failure reported. • The PCM cancels the DTC default actions when the fault no longer exists and the ignition is OFF long enough in order to power down the PCM. • Check for PRNDL DTC P0705. DTC P0705 affects transmission operation. This may set DTC P0502 falsely. • Check for Electromagnetic Interference (EMI) in circuits 400 and 401. EMI may be induced if the harness is routed along the spark plug wires. • Inspect the wiring for poor electrical connections at the PCM. Inspect the wiring at the TCC brake switch. Look for the following conditions: – A bent terminal – A backed out terminal – A damaged terminal – Poor terminal tension – A chafed wire – A broken wire inside the insulation • When diagnosing for an intermittent short or open condition, massage the wiring harness while watching the test equipment for a change. • Ensure that the VSS is securely tightened to the case extension.
