Diagnostic Test

CHECK FOR CHARGING OR VOLTAGE RELATED DTC(S) PRESENT IN OTHER MODULES
1. With the scan tool, read the PCM DTCs and record on the repair order.
  Are there any charging system or battery voltage related DTCs present?
  
  Yes
  - Repair the Powertrain Control Module (PCM) DTCs before continuing with this test. Refer to DTC INDEX .
  No
  - Go To 2
CHECK FOR AN ACTIVE DTC
1. Verify the Left and Right Multifunction Switch and Clockspring harness connectors are properly seated and verify proper pin terminal tension. Refer to the appropriate Service information.
  NOTE:
  A loose connection at any of these connectors may cause this DTC to set.
2. With the scan tool, read Steering Column Control Module (SCCM) DTCs and record on the repair order.
3. Record the Environmental Data and any DTCs.
4. With the scan tool, erase DTCs.
5. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
6. With the scan tool, read SCCM DTCs.
  Did the DTC return?
  
  Yes
  - Go to 3
  No
  - Test complete. The condition or conditions that originally set this DTC are not present at this time.
  - Perform the appropriate TESTING FOR AN INTERMITTENT diagnostic procedure. Refer to TESTING FOR AN INTERMITTENT CONDITION .
(A234) FUSED B(+) CIRCUIT OPEN OR HIGH RESISTANCE
2. Turn the ignition off
3. Disconnect the SCCM Module harness connector.
4. Turn the ignition on.
5. Using a 12-volt test light connected to ground, check (A234) Fused B(+) circuit in the SCCM Module harness connector.
  NOTE:
  The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.
  
  Does the test light illuminate brightly?
  
  Yes
  - Go to 4
  No
  - Repair the (A234) Fused B(+) circuit for an open or high resistance.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
(Z911) GROUND CIRCUIT OPEN OR HIGH RESISTANCE
1. Turn the ignition off
2. Using a 12-volt test light connected to 12-volts, check the (Z911) Ground circuit in the SCCM Module harness connector.
  NOTE:
  The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.
  
  Does the test light illuminate brightly?
  
  Yes
  - Go to 5
  No
  - Repair the Ground circuit for an open or high resistance.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
CHECK RELATED HARNESS CONNECTIONS
1. Disconnect all SCCM Module harness connectors.
2. Disconnect all related in-line harness connections (if equipped).
3. Disconnect the related component harness connectors.
4. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
  - Proper connector installation.
  - Damaged connector locks.
  - Corrosion.
  - Other signs of water intrusion.
  - Weather seal damage (if equipped).
  - Bent terminals.
  - Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
  - Terminals that have been pushed back into the connector cavity.
  - Perform a terminal drag test on each connector terminal to verify proper terminal tension.
  Repair any conditions that are found.
5. Reconnect all SCCM Module harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
6. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
7. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
8. With the scan tool, erase DTCs.
9. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
10. With the scan tool, read SCCM Module DTCs.
  Did the DTC return?
  
  Yes
  - Replace the Steering Column Control Module (SCCM) in accordance with the Service Information. Refer to MODULE, STEERING COLUMN CONTROL (SCCM), REMOVAL .
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  - Test complete.
