Diagnostic Test

  1. DTC IS ACTIVE 
    1. Turn the ignition on.
    2. With the scan tool, Clear DTCs in the Powertrain Control Module (PCM).
    3. With the scan tool, actuate the Auto Shutdown (ASD) Relay Control State.
    4. With the scan tool, select View DTCs.

      Is the status Active for this DTC?

      Yes 

      • Go to step  2

      No 

  2. FUSED B(+) CIRCUIT OPEN OR HIGH RESISTANCE

    NOTE: Before continuing, inspect the related fuses. Repair as necessary.
    1. Turn the ignition off.
    2. Remove the Auto Shut Down Relay from the TIPM.
    3. Turn the ignition on.
    4. Using a 12 volt test light connected to ground, check both Fused B(+) circuits in the Auto Shut Down Relay connector.
      NOTE: The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.

      Is the test light illuminated and bright?

      Yes 

      • Go to step  3

      No 

  3. ASD RELAY OUTPUT CIRCUIT SHORTED TO VOLTAGE 
    1. Turn the ignition off.
    2. Disconnect the Powertrain Control Module (PCM) connectors.
    3. Turn the ignition on.
    4. Measure the voltage of the ASD Relay Output circuit in the Auto Shut Down Relay connector.

      Is there any voltage present?

      Yes 

      No 

      • Go to step  4
  4. ASD RELAY OUTPUT CIRCUIT SHORTED TO GROUND (TIPM) 
    1. Disconnect the C6 TIPM harness connector.
    2. Measure the resistance between ground and the ASD Relay Output circuit at the Auto Shut Down Relay terminal in the TIPM.

      Is the resistance below 100 ohms?

      Yes 

      No 

      • Go to step  5
  5. (F342) ASD RELAY OUTPUT CIRCUIT SHORTED TO GROUND 
    1. Measure the resistance between ground and the (F342) ASD Relay Output circuit in the C6 TIPM harness connector.

      Is the resistance below 100 ohms?

      Yes 

      No 

      • Go to step  6
  6. ASD RELAY OUTPUT CIRCUIT OPEN OR HIGH RESISTANCE (TIPM) 
    1. Measure the resistance of the ASD Relay Output circuit between the C6 TIPM harness connector and the terminal pin in the back of the TIPM.

      Is the resistance below 5.0 ohms?

      Yes 

      • Go to step  7

      No 

  7. (F342) ASD RELAY OUTPUT CIRCUIT OPEN OR HIGH RESISTANCE 
    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 Miller Special Tool #8815 to perform diagnosis.
    1. Measure the resistance of the (F342) ASD Relay Output circuits between the C6 TIPM harness connector and each of the appropriate terminals of special tool #8815.

      Is the resistance below 5.0 ohms?

      Yes 

      • Go to step  8

      No 

  8. AUTO SHUT DOWN RELAY 
    1. Turn the ignition off.
    2. Install the Auto Shut Down Relay.
      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 Miller Special Tool #8815 along with the #8815-1 to perform the diagnosis.
    3. Turn the ignition on.
    4. With the scan tool, actuate the Auto Shutdown (ASD) Relay Control State.
    5. Measure the voltage of each of the (F342) ASD Relay Output circuits in the appropriate terminals of special tool #8815-1.
      NOTE: If the DTC is active, the actuation test may not be allowed by the PCM. If may be necessary to clear the DTCs before starting the actuation.
      NOTE: The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.

      Is the test light illuminated and bright for each of the circuits during the actuation?

      Yes 

      • Go to step  9

      No 

  9. POWERTRAIN CONTROL MODULE (PCM) 
    1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Auto Shut Down 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.
    4. Refer to any Technical Service Bulletins that may apply.

      Were any problems found?

      Yes 

      No
