Control Module HVAC: Testing and Inspection

Voltage Supply And Grounding
The ACC control module is supplied with voltage from +30 and +15.

+30 gives power voltage and is fed via fuse 17 in fuse holder 22A to the ACC control module.

+15 is used to start the ACC control module and is fed via fuse 1 in fuse holder 22A to the ACC control module.

The ACC control module functions when supply voltage is 10-16 volts. Outside this range, the ACC control module goes into OFF mode.
