as spark plug wires. Test Description The numbers below refer to the step numbers on the diagnostic table. 3: This step tests the wheel speed sensor for the proper resistance value. 4: This step ensures that the wheel speed sensor generates the proper voltage. DTC C0035-C0051 Step or Action Value(s) Yes No Schematic Reference: ABS Schematics 1 Did you perform the ABS Diagnostic System Check? - Go to Step 2 Go to Diagnostic System Check - ABS 2 1. Install a scan tool. 2. Turn ON the ignition. 3. Set up the scan tool snap shot feature to trigger for this DTC. 4. Drive the vehicle at a speed greater than the specified value. Does the scan tool indicate that this wheel speed DTC set? 40 km/h (25 mph) Go to Step 3 Go to Diagnostic Aids 3 1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information. 2. Disconnect the wheel speed sensor connector. 3. Measure the resistance across the wheel speed sensor. Does the resistance measure within the specified range? Front Wheels 800-1600 ohm Rear Wheels 4500-5400 ohm Go to Step 4 Go to Step 8 4 1. Spin the wheel. 2. Measure the AC voltage across the wheel speed sensor. Does the AC voltage measure greater than the specified 100 mV Go to Step 5 Go to Step 8 5 Inspect for poor connections at the harness connector of the - Go to Step 10 Go to Step 6
