  1. Turn the ignition switch to ON.
  2. Connect the check board.

    ST 18460AA050 CHECK BOARD

  3. Measure the voltage between ECM connector and engine ground while wiggling the harness between ECM connector and F/B connector.

    Connector & terminal 

    (B134) No. 27 (+) - Engine ground (-): 

 Is the voltage 8 V or more all the time? Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.
NOTE: In this case, the following items may be the cause of fault.
  • Open circuit or short circuit to ground in harness between ECM connector and F/B connector
  • Poor contact of fuse (F/B No. 5)
  • Poor contact of IG2 relay connector
  • Poor contact of IG2 relay
 Repair the harness and connector.
NOTE: In this case, repair the following item:
  • Open circuit or short circuit to ground in harness between ECM connector and F/B connector
  • Poor contact of fuse (F/B No. 5)
  • Poor contact of IG2 relay connector
  • Poor contact of IG2 relay
