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
  - Perform the INTERMITTENT CONDITION Diagnostic Procedure. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
(A922) FUSED B+ CIRCUITS

1. Turn the ignition off.
2. Remove the ASD Relay from the IPM.
3. Using a 12-volt test light connected to ground, probe the (A922) Fused B+ circuits in the IPM.
  Does the test light illuminate brightly?
  
  Yes
  - Go to step 3
  No
  - Repair the open or short to ground in the (A922) Fused B+ circuits. Inspect and replace any open fuses.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
ASD RELAY
1. Measure the resistance of the ASD Relay Coil.
  Is the resistance between 60 to 80 Ohms?
  
  Yes
  - Go to step 4
  No
  - Verify that there is good pin to terminal contact in the ASD Relay and Powertrain Control Module connectors. If OK, replace the ASD Relay.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
(K51) ASD RELAY CONTROL CIRCUIT OPEN

1. Disconnect the C3 PCM harness connector.
  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 Relay Control circuit from the IPM to the appropriate terminals of special tool #8815.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go to step 5
  No
  - Repair the open in the (K51) ASD Relay Control circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
(K51) ASD RELAY CONTROL CIRCUIT SHORTED TO GROUND

1. Measure the resistance between ground and the (K51) ASD Relay Control circuit in the IPM.
  Is the resistance below 100 Ohms?
  
  Yes
  - Repair the short to ground in the (K51) ASD Relay Control circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  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 ASD Relay 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 ASD Relay 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. Refer to 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. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
