Diagnostic Test

1) ACTIVE DTC
Ignition on, engine not running.

With a scan tool, select View DTCs.

Is the DTC Active at this time?

Yes
1. Go To 2).
No
1. Refer to INTERMITTENT CONDITION Diagnostic Procedure.
2) INTERNAL FUSED B+ CIRCUITS

Turn the ignition off.

Remove the ASD Relay from the PDC.

Using a 12-volt test light connected to ground, probe the Internal Fused B+ circuits in the PDC.

Does the test light illuminate brightly?

Yes
1. Go To 3).
No
1. Repair the open or short to ground in the Internal Fused B+ circuits. Inspect and replace any open fuses.
2. Perform POWERTRAIN VERIFICATION TEST .
3) ASD RELAY
Measure the resistance of the ASD Relay Coil.

Is the resistance between 60 to 80 ohms?

Yes
1. Go To 4).
No
1. Replace the ASD Relay.
2. Perform POWERTRAIN VERIFICATION TEST .
4) (K342) ASD RELAY CONTROL CIRCUIT OPEN

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 Miller Special Tool #8815 to perform diagnosis.

Measure the resistance of the (K342) ASD Relay Control circuit from the PDC to the appropriate terminals of special tool #8815.

Is the resistance below 5.0 ohms?

Yes
1. Go To 5).
No
1. Repair the open in the (K342) ASD Relay Control circuit.
2. Perform POWERTRAIN VERIFICATION TEST .
5) (K342) ASD RELAY CONTROL CIRCUIT SHORTED TO GROUND

Measure the resistance between ground and the (K342) ASD Relay Control circuit in the PDC.

Is the resistance below 100 ohms?

Yes
1. Repair the short to ground in the (K342) ASD Relay Control circuit.
2. Perform POWERTRAIN VERIFICATION TEST .
No
1. Go To 6).
6) PCM
NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.

Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and Ground circuits.

Were there any problems found?

Yes
1. Repair as necessary.
2. Perform POWERTRAIN VERIFICATION TEST .
No
1. Replace and program the Powertrain Control Module per Service Information.
2. Perform POWERTRAIN VERIFICATION TEST .
