Fault Code 10

Fault Code 10:

1. Set ATC control to Off mode, then remove ATC control.
2. Measure voltage at ATC control connector pin 15.
- 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 15 and PVM pin 2.
- If continuity exists, replace PVM.
- If continuity does not exist, repair circuit and recheck system.
