Checking the Power Supply And Ground Terminal
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2009 Volvo S60, 2008 Volvo S60, 2007 Volvo S60, 2006 Volvo S60, and 2005 Volvo S60. However, it is still accessible from the selected car via links, so may be relevant.
Checking the power supply
- Check the fuse for power supply to control module terminal #C1 (#31).
If the fuse is blown, check the circuit for a short-circuit to ground
- Check the power supply to the control module (terminal #31). The voltage must be battery voltage (Ubat) when the ignition is on.
If the voltage is not correct, check the cable between the system relay and control module terminal #C1 (terminal #31). Check for contact resistance or an open-circuit.
Checking ground terminal
- Check the ground leads between control module terminal #C2 (#32) and the ground terminal in the chassis. Check for an open-circuit
- Check the ground terminal for the control module in the chassis. Check for contact resistance and oxidation.
