P1389-NO ASD RELAY OUTPUT VOLTAGE AT PCM (CONTINUED) 3. (K342) ASD OUTPUT CIRCUIT OPEN Turn the ignition off. Remove the ASD Relay from the PDC. Disconnect the PCM harness connectors. Measure the resistance of the (K342) ASD Relay Output circuit from the ASD Relay cavity in the PDC to the PCM Is the resistance below 5.0 ohms? Yes >> Go To 7 No >> Repair the open in the (K342) ASD Relay Output circuit. Perform POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) 4. ASD RELAY Install a substitute relay for the ASD Relay. Attempt to start the vehicle. Did the engine start? Yes >> Replace the ASD Relay. Perform POWERTRAIN VERIFICATION TEST VER - 2. No >> Go To 5 5. (A14) FUSED B+ CIRCUITS Turn the ignition off. Remove the ASD Relay from the PDC. Using a 12-volt test light, probe the (A14) Fused B+ circuits at the ASD Relay connector in the PDC. Does the test light illuminate brightly? Yes >> Go To 6 No >> Repair the open or short to ground in the (A14) Fused B+ circuits. Inspect the related fuse and repair as necessary. Perform POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) 6. (K342) ASD RELAY OUTPUT CIRCUIT OPEN Disconnect the PCM harness connectors. Measure the resistance of the (K342) ASD Relay Output circuit from the ASD Relay cavity in the PDC to the PCM Is the resistance below 5.0 ohms? Yes >> Go To 7 No >> Repair the open in the (K342) ASD Relay Output circuit. Perform POWERTRAIN VERIFICATION TEST.
