Diagnostic Test

VERIFY DTC IS ACTIVE
NOTE: Ensure the IOD fuse is installed and battery voltage is between 10 and 16 volts before proceeding.
1. Turn the ignition on.
2. With the scan tool, read and record ABS DTCs.
3. With the scan tool, read and record Environmental Data to help identify the conditions in which the DTC was set.
4. With the scan tool, erase ABS DTCs.
5. Cycle the ignition switch.
6. With the scan tool, read ABS DTCs.
  Does this DTC reset?
  
  Yes
  - Go to step 2
  No
  - The condition that caused the symptom is currently not present. Inspect the related wiring for a possible intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires.
  - Perform the ABS-INTERMITTENT CONDITION TEST. See DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure .
CHECK FOR ANY OF THE FOLLOWING ACTIVE DTCs
1. With the scan tool, read all active DTCs from all CAN C Bus modules.
  NOTE: Check for CAN C hardware electrical, VIN Missing/Mismatch, battery or ignition related DTCs.
  
  Does the scan tool display any active DTCs related to the conditions listed above?
  
  Yes
  - Diagnose and repair the DTC(s). Check the DIAGNOSTIC CODE INDEX .
  No
  - Go to step 3
CHECK THE VOLTAGE OF THE STEERING CONTROL MODULE (A913) FUSED B(+) CIRCUIT

1. Turn the ignition off.
2. Disconnect the Steering Control Module harness connector.
3. Turn the ignition on.
4. Measure the voltage of the (A913) Fused B(+) circuit.
  Is the voltage above 10 volts?
  
  Yes
  - Go to step 4
  No
  - Repair the (A913) Fused B(+) circuit for an open.
  - Perform ABS VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure .
CHECK THE RESISTANCE OF THE STEERING CONTROL MODULE (Z910) GROUND CIRCUIT

1. Measure resistance between the (Z910) Ground circuit and ground.
  Is the resistance below 5.0 ohms?
  
  Yes
  - Go to step 5
  No
  - Repair the (Z910) Ground circuit for an open.
  - Perform ABS VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure .
VERIFY THAT THE STEERING ANGLE SENSOR IS ACTIVE ON THE BUS
1. With the scan tool, select ECU View.
2. Verify that the Steering Angle Sensor is active on the bus.
  Is the Steering Angle Sensor active on the bus?
  
  Yes
  - Replace the Steering Angle Sensor in accordance with the service information.
  - Perform ABS VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure .
  No
  - Perform the Stored Lost Communication test procedure. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Diagnosis and Testing .
