Checking the Power Supply



1 Check that fuses 17 and 34 are intact and live.





2 Connect a BOB and check whether voltage is present on pins 9 and 15 by taking a reading across pin 9 and a good ground and also across pin 15 and a good ground.

The reading should be 12v.

3 If the voltage reading is not OK, check the wiring for continuity/shorting.

Take readings between the fuses and the control module connector.
