Diagnostic Test

ACTIVE DTC
1. Ignition on, engine not running.
2. With a scan tool, select View DTCs.
  Is the DTC Active at this time?
  
  Yes
  - Go to step 2
  No
  - Refer to the INTERMITTENT CONDITION Diagnostic Procedure. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .

1. Turn the ignition off.
2. Disconnect the C3 PCM harness connector.
3. Disconnect the C2 TIPM harness connector.
4. Ignition on, engine not running.
5. Measure the voltage on the (K51) ASD Control circuit at the C2 TIPM harness connector.
  Does the voltmeter indicate voltage present?
  
  Yes
  - Go to step 3
  No
  - Repair the short to voltage in the (K51) ASD Control circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
(K51) ASD CONTROL CIRCUIT OPEN

1. Turn the ignition off.
  CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install PCM Pinout Box 8815 to perform diagnosis.
2. Measure the resistance of the (K51) ASD Control circuit from the TIPM harness connector to the appropriate terminals of special tool #8815.
  Is the resistance below 5.0 ohms?
  
  Yes
  - Go to step 4
  No
  - Repair the open in the (K51) ASD Control circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
(K51) ASD CONTROL CIRCUIT SHORTED TO GROUND

1. Measure the resistance between ground and the (K51) ASD Control circuit at the C2 TIPM harness connector.
  Is the resistance below 100 ohms?
  
  Yes
  - Repair the short to ground in the (K51) ASD Control circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 5
ASD CONTROL OPERATION FROM THE PCM

1. Connect the C3 PCM harness connector.
2. Ignition on, engine not running.
3. Using the scan tool in the PCM, actuate the ASD.
4. With a 12-volt test light connected to ground, probe the (K51) ASD Control circuit in the C2 TIPM harness connector.
  Does the test light illuminate brightly and flash on and off?
  
  Yes
  - If OK, replace the TIPM in accordance with the Service Information.
  No
  - Go to step 6
POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the related TIPM and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched, or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the TIPM and Powertrain Control Module connectors.
4. Refer to any Technical Service Bulletins that may apply.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Replace and program the Powertrain Control Module per Service Information.
  - Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
