Auto Shutdown Relay Control Circuit (DTC 42)

NOTE: For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagrams, see WIRING DIAGRAMS - 2.5L V6 article in ENGINE PERFORMANCE.
  1. Using scan tool, actuate Auto Shutdown (ASD) relay. If ASD relay is clicking, go to next step. If ASD relay is not clicking, go to step 5).
  2. At this time, condition required to set trouble code is not present. AUTO SHUTDOWN RELAY CONTROL CIRCUIT trouble code sets if an open or short is detected in ASD relay control circuit. Possible causes are: ASD relay coil open or shorted, open in ASD relay Black/White wire (FJ22 body) or Red/Tan wire (JA body), open or short in ASD relay Red/White wire (FJ22 body) or Dark Blue/Violet wire or inoperative circuit driver in PCM. Go to next step.
  3. Inspect all related wiring and connectors and repair as necessary. Perform TEST VER-2 . If no problems are found with wiring and connectors, go to next step.
  4. Start engine. Wiggle wiring harness from ASD relay to PCM. If engine stalled while wiggling wiring harness, repair wiring and connectors as necessary. Perform TEST VER-2. If engine did not stall while wiggling wiring harness, see INACTIVE TROUBLE CODE CONDITION . Perform TEST VER-2.
  5. Disconnect ASD relay. Put scan tool in voltmeter mode. On FJ22 body, using scan tool, check voltage on ASD relay connector terminal "C" Black/White wire. On JA body, using scan tool, check voltage on ASD relay connector terminal "A" Red/Tan wire. On all models, if voltage is less than 10 volts, repair open in appropriate wire. Perform TEST VER-2. If voltage is more than 10 volts, turn ignition off.
  6. Using an external ohmmeter, check resistance between ASD relay terminals. See Fig 1. If resistance is more than 100 ohms, replace ASD relay. Perform TEST VER-2. If resistance is less than 100 ohms, go to next step.

  7. Turn ignition off. Disconnect PCM connector. Put scan tool in ohmmeter mode. Using scan tool, check resistance of ASD relay connector Red/White wire (FJ22 body) or Dark Blue/Violet wire (JA body). If resistance is less than 5 ohms, repair short to ground in appropriate wire. Perform TEST VER-2. If resistance is more than 5 ohms, go to next step.
  8. Using an external ohmmeter, check resistance of Red/White wire (FJ22 body) or Dark Blue/Violet wire (JA body) between ASD relay connector and PCM connector terminal No. 67. If resistance is more than 5 ohms, repair open in appropriate wire. Perform TEST VER-2 . If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2.
