Ground Circuits

  1. Turn ignition off. Disconnect ECU connector. See Figure and Figure . Using DVOM, check resistance between ECU connector terminals No. 10, No. 20, No. 32 and No. 34 and ground. Resistance should be zero in all cases.
  2. If resistance is not correct, check wiring harness between ECU and ground connections. Circuits No. 10, No. 20 and No. 34 are grounded behind driver kickpanel. If fault is found at terminal No. 32, retest with new solenoid valve relay. See Figure .
