Engine Controller (Fwd Models Only)

  1. Disconnect 60-pin connector from engine controller, located next to battery. Turn ignition on. Connect voltmeter negative lead to ground. Connect voltmeter positive lead to cavity No. 53 of 60-pin connector. See Fig 1 .
  2. With speed control switch in "ON" position, voltmeter should read zero volt. With speed control switch in "ON" position, voltmeter should read battery voltage. If not as specified, repair main harness as necessary.
  3. Connect voltmeter positive lead to cavity No. 60 of 60-pin connector. See Fig 1 . With speed control switch in "ON" position, voltmeter should read battery voltage. With speed control switch in "OFF" position, voltmeter should read zero volt. If not as specified, repair main harness as necessary.
  4. Connect voltmeter positive lead to cavity No. 9 of 60-pin connector. See Fig 1 . With speed control switch in "OFF" position, voltmeter should read zero volt. With speed control switch in "ON" position, voltmeter should read battery voltage.
  5. Press SET button, voltmeter reading should change battery voltage to zero volt for as long as switch is held. If not, check speed control switch. If switch is okay, check or repair main harness.
  6. Connect voltmeter positive lead to cavity No. 7 of 60-pin connector. Voltmeter should read zero volt with speed control switch in either "OFF" or "ON" positions. With switch in either "RESUME" or "SET" position, voltmeter should read battery voltage. If not, check speed control switch. If switch is okay, check or repair main harness.
  7. Connect voltmeter positive lead to cavity No.8. Voltmeter should read zero volt with speed control switch in "OFF" position. With switch in "ON" position, voltmeter should read battery voltage. Voltmeter should continue to read battery voltage when either "SET" or "RESUME" switch is pressed. If not, check speed control switch. If okay, check or repair main harness.
  8. Using an ohmmeter, connect one lead to ground and the other lead to cavity No. 29 of 60-pin connector. With brake pedal released, ohmmeter should read continuity. With brake pedal depressed, ohmmeter should show open circuit.
