Test Description

The numbers below refer to the step numbers on the diagnostic table.

  1. 2:  Perform the Steering Position Sensor Test in order to verify if the steering wheel position sensor (SWPS) is operating properly.
  2. 3:  Tests for the proper operation of the steering wheel position signal A circuit in the low voltage range.
  3. 4:  Tests for the proper operation of the steering wheel position signal B circuit in the low voltage range.
  4. 5:  Tests for the proper operation of the steering wheel position signal A circuit in the high voltage range. If the fuse in the jumper opens when you perform this test, the signal circuit is shorted to ground.
  5. 6:  Tests for the proper operation of the steering wheel position signal B circuit in the high voltage range. If the fuse in the jumper opens when you perform this test, the signal circuit is shorted to ground.
  6. 7:  Tests for a short to voltage in the 5-volt reference circuit.
  7. 8:  Tests for a high resistance or an open in the low reference circuit.

1 Did you perform the Diagnostic System Check - Vehicle? - Go to Step 2  Go to Diagnostic System Check - Vehicle
2 
  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. With the scan tool, perform the Steering Position Sensor Test.
Did the steering wheel position sensor (SWPS) pass the test?		 - Go to Diagnostic Aids Go to Step 3 
3 
  1. Turn OFF the ignition.
  2. Disconnect the SWPS connector.
  3. Turn ON the ignition, with the engine OFF.
  4. With the scan tool, observe the SWPS Signal A parameter in the Vehicle Stability Enhancement System (VSES) data list.
Does the scan tool indicate the SWPS Signal A parameter is less than the specified value?		 0.2 V Go to Step 4  Go to Step 13 
4  With the scan tool, observe the SWPS Signal B parameter.
Does the scan tool indicate the SWPS Signal B parameter is less than the specified value?		 0.2 V Go to Step 5  Go to Step 14 
5 
  1. Turn OFF the ignition.
  2. Connect a 3-amp fused jumper wire between the 5-volt reference circuit of the SWPS and the signal A circuit of the SWPS.
  3. Turn ON the ignition, with the engine OFF.
  4. With the scan tool, observe the SWPS Signal A parameter.
Does the scan tool indicate that the SWPS Signal A parameter is greater than the specified value?		 4.9 V Go to Step 6  Go to Step 10 
6 
  1. Turn OFF the ignition.
  2. Disconnect the fused jumper wire.
  3. Connect a 3-amp fused jumper wire between the 5-volt reference circuit of the SWPS and the signal B circuit of the SWPS.
  4. Turn ON the ignition, with the engine OFF.
  5. With the scan tool, observe the SWPS Signal B parameter.
Does the scan tool indicate that the SWPS Signal B parameter is greater than the specified value?		 4.9 V Go to Step 7  Go to Step 10 
7 
  1. Disconnect the fused jumper wire.
  2. Measure the voltage between the 5-volt reference circuit of the SWPS and the low reference circuit of the SWPS.
Does the voltage measure less the specified value?		 5 V Go to Step 8  Go to Step 9 
8  Measure the resistance from the low reference circuit of the SWPS to a good ground.
Does the resistance measure less than the specified value?		 5 Ω Go to Step 16  Go to Step 15
