Test TC-10A: Auto Shutdown Relay Control Circuit
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS article.
- Using scan tool, actuate Auto Shutdown (ASD) relay. Listen for clicking sound at ASD relay. On Avenger, Sebring Coupe and Talon, ASD relay is located in left rear corner of engine compartment. On Breeze, Cirrus, Neon, Sebring Convertible and Stratus, ASD relay is located in Power Distribution Center (PDC) in engine compartment. If ASD relay is clicking, go to next step. If ASD relay is not clicking, go to step 5) .
- Condition to set trouble code is not present at this time. AUTO SHUTDOWN RELAY CONTROL CIRCUIT DTC sets if an open or shorted condition is detected in ASD relay control circuit. Possible causes are: ASD relay coil open or shorted, fused ignition switch circuit open, ASD relay control circuit open or shorted, inoperative driver in Powertrain Control Module (PCM), PCM failure or poor connections. Go to next step.
- Inspect all related wiring and connectors and repair as necessary. If no problems were found with wiring and connectors, go to next step. If related wiring and connectors were repaired, perform TEST VER-2A .
- Start engine. Wiggle wiring harness from ASD relay to PCM. If engine misfired or stalled, repair wiring harness as necessary. Perform TEST VER-2A . If engine did not misfire or stall, see INACTIVE TROUBLE CODE CONDITION . Test is complete. Perform TEST VER-2A .
- Disconnect ASD relay. Using a voltmeter, check voltage of both ASD relay connector fused B+ circuits. See ASD RELAY CONNECTOR WIRE IDENTIFICATION table. When checking fused B+ circuit, ensure circuit is tested at both terminals (one at a time) of ASD relay connector. ASD relay is located in underhood Power Distribution Center (PDC). If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open fused B+ circuit. See ASD RELAY CONNECTOR WIRE IDENTIFICATION table. Perform TEST VER-2A .
- Using an ohmmeter, check resistance between ASD relay terminals No. 85 and 86. See Fig 1. If resistance is less than 100 ohms, go to next step. If resistance is 100 ohms or more, replace ASD relay. Perform TEST VER-2A .
- Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Using an ohmmeter, check resistance of ASD relay control circuit at ASD relay connector. See ASD RELAY CONNECTOR WIRE IDENTIFICATION table for wire identification. If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, repair short to ground in ASD relay control circuit. Perform TEST VER-2A .
- Using an ohmmeter, measure resistance of ASD relay control circuit between ASD relay connector and PCM connector. See ASD RELAY CONNECTOR WIRE IDENTIFICATION table and PCM CONNECTOR WIRE IDENTIFICATION table for wire identification. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2A . If resistance is 5 ohms or more, repair open ASD relay control circuit. Perform TEST VER-2A .
