NOTE:
For connector terminal identification, refer to CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS
article in this section.
- Using scan tool, actuate Auto Shutdown (ASD) relay. Listen for clicking sound at ASD relay. If no clicking sound is heard at ASD relay, go to step 6). If clicking sound is heard at ASD relay, go to next step.
- Condition required to set DTC is not present at this time. AUTO SHUTDOWN RELAY CONTROL CIRCUIT sets if Powertrain Control Module (PCM) detects an open or shorted condition in ASD relay control circuit. Possible causes are: open or shorted relay coil, open fused ignition output circuit, open or shorted ASD relay control circuit, defective PCM, defective connector terminals or connector wires. Go to next step.
- Inspect all related wiring and connectors. Repair wiring and connectors as necessary and perform TEST VER-2A. If wiring and connectors are okay, start engine. Go to next step.
- Wiggle wiring harness from ASD relay to PCM. If engine stalls while wiggling wiring harness, repair wiring as necessary and perform TEST VER-2A . If engine does not stall, see procedures under INACTIVE DTC CONDITION . Test is complete. Perform TEST VER-2A.
- Disconnect intake air temperature heater relay control connector. Turn headlights on and wiggle wiring harness from ASD relay to PCM. If headlights flicker while wiggling wiring harness, repair wiring as necessary and perform TEST VER-2A. If headlights do not flicker, see INACTIVE DTC CONDITION . Test is complete. Perform TEST VER-2A.
