Fault Code 8

Fault Code 8:

1. Set ATC control to Defrost mode, then remove ATC control.
2. Measure voltage at ATC control connector pin 5.
- If voltage measures less than 4 volts, proceed to step 3.
- If voltage measures more than 4 volts, replace ATC control.
3. If voltage measures 0.4-0.8 volt, replace ATC control. If voltage does not measure 0.4-0.8 volt, proceed to step 4.
4. Disconnect 13-way connector from PVM, then check for continuity between ATC control pin 5 and PVM pin 5.
- If continuity exists, replace PVM.
- If continuity does not exists, repair circuit and recheck system.
