Test Description

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

  1. 2. Tests if the Commanded Current parameter is at the specified value in the active state.
  2. 3. Tests if the resistance of the VES actuator is in the specified range.
  3. 7. Tests the high effort control circuit for an open or short to voltage.
  4. 8. Tests the low effort control circuit for a short to ground. 10. Tests for poor connections at the VES actuator harness connector.
DTC C2203 TESTING CURRENT DIAGNOSTIC PROCEDURE

Step Action Value(s) Yes No
1 Did you perform the Variable Effort Steering Diagnostic System Check? - Go to Step 2. Go to DIAGNOSTIC SYSTEM CHECK-VARIABLE EFFORT STEERING .
2
  1. Install a scan tool.
  2. Start the engine.
  3. With the scan tool, observe the SSS Commanded Current parameters in the Speed Sensitive Steering data list.

Does the scan tool indicate that the SSS Commanded Current parameter is within specified range?		 - Check for intermittent and poor connections in wiring systems. Go to Step 3.
3
  1. Turn OFF the ignition.
  2. Disconnect the VES actuator harness connector.
  3. Measure the resistance of the VES actuator.

Does the resistance measure within the specified range?		 - Go to Step 4. Go to Step 10.
4 Check the VES actuator and actuator harness for a short to ground. Was a short to ground located? - Go to Step 5. Go to Step 6.
5 Visually inspect the actuator harness for any cut, chaffed or damaged wires.
Did you find and correct the condition?		 - Go to Step 14. Go to Step 12.
6 Check the high effort control circuit of the VES actuator for a short to ground. Did you find and correct the condition? - Go to Step 14. Go to Step 7.
7 Check the high effort control circuit of the VES actuator for an open or short to voltage.
Did you find and correct the condition?		 - Go to Step 14. Go to Step 8.
8 Check the low effort control circuit of the VES actuator for a short to ground. Did you find and correct the condition? - Go to Step 14. Go to Step 9.
9 Check the low effort control circuit of the VES actuator for an open or short to voltage.
Did you find and correct the condition?		 - Go to Step 14. Go to Step 11.
10 Inspect for poor connections at the harness connector of the VES actuator.
Did you find and correct the condition?		 - Go to Step 14. Go to Step 12.
11 Inspect for poor connections at the harness connector of the SSPS control module.
Did you find and correct the condition?		 - Go to Step 14. Go to Step 13.
12 Replace the VES actuator.
Did you complete the repair?		 - Go to Step 14. -
13 Replace the power steering control module.
Did you complete the replacement?		 - Go to Step 14. -
14 Operate the system in order to verify the repair.
Did you correct the condition?		 - System OK Go to Step 2.
