DIAGNOSTIC PROCEDURE

Step Check Yes No
1 CHECK INPUT VOLTAGE OF ECM. 
  1. Turn the ignition switch to ON.
  2. Measure the voltage between ECM and chassis ground.

    Connector & terminal 

    (B136) No. 1 (+) - Chassis ground (-): 

    (B137) No. 7 (+) - Chassis ground (-): 

 Is the voltage 10 - 13 V? Go to step 2  . Repair the open or ground short circuit of power supply circuit.
2 CHECK INPUT VOLTAGE OF ECM. 
  1. Start the engine.
  2. Measure the voltage between ECM and chassis ground.

    Connector & terminal 

    (B136) No. 1 (+) - Chassis ground (-): 

    (B137) No. 7 (+) - Chassis ground (-): 

 Is the voltage 13 - 15 V? Go to step 3  . Repair the open or ground short circuit of power supply circuit.
3 CHECK HARNESS BETWEEN ECM AND ELECTRONIC THROTTLE CONTROL CONNECTOR. 
  1. Turn the ignition switch to OFF.
  2. Disconnect the connectors from ECM and electronic throttle control.
  3. Measure the resistance of harness between ECM and electronic throttle control connector.

    Connector & terminal 

    (B134) No. 19 - (E57) No. 5: 

    (B134) No. 29 - (E57) No. 3: 

 Is the resistance less than 1 Ω? Go to step 4  . Repair the harness and connector.
NOTE: In this case, repair the following item:
  • Open circuit in harness between ECM and electronic throttle control connector
  • Poor contact of coupling connector
4 CHECK ECM GROUND HARNESS. 
  1. Connect all connectors.
  2. Turn the ignition to ON.
  3. Measure the voltage between ECM and chassis ground.

    Connector & terminal 

    (B134) No. 3 (+) - Chassis ground (-): 

    (B134) No. 4 (+) - Chassis ground (-): 

    (B134) No. 6 (+) - Chassis ground (-): 

    (B137) No. 1 (+) - Chassis ground (-): 

    (B137) No. 3 (+) - Chassis ground (-): 

 Is the voltage less than 1 V? Repair the poor contact of ECM connector. Repair the harness and connector.
NOTE: In this case, repair the following item:
  • Open circuit in ground circuit
  • Loose engine ground terminal
  • Poor contact of coupling connector
