Ground Circuits

WARNING: This page is about a different car, the 1989 Volvo 760 and 1989 Volvo 740. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off. Using a DVOM, check resistance between ECU connector terminals No. 10, 20, 32 and 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, 20 and 34 are grounded behind driver kickpanel. If a fault is found at terminal No. 32, test with a new solenoid valve relay. See Figure.
