Checking the Power Supply

1 Ignition switch in the LOOK position. Connect a BOB and check the power supply for the Cruise Control system's control module by taking a voltage reading across pin F (6) of the control module connector and a good ground (e.g. a door hinge screw).
The reading should be about 12 V.
2 If the reading is not 12 V, check the wiring for continuity or a short circuit by measuring the resistance across pin F (6) of the control module connector and the load side of the fuse.
The resistance should be ≤ 1 ohm.
3 If no fault has been found after carrying out the above checks, continue as described.
