Yes Repair the (A417) Fused B(+) circuit for an open or high resistance. NOTE: If the fuse is open, make sure to check for a short to ground on the (A417) Fused B(+) circuit. Perform the HVAC VERIFICATION TEST. Refer to «HVAC VERIFICATION TEST»(ref-485533-S34738617912012071300000) . No Go To 6 .
6. CHECK THE (Z912) GROUND CIRCUIT FOR AN OPEN Turn the ignition off to the lock position. Disconnect the A/C Heater Control C1 harness connector. Using a 12-volt test light connected to 12-volts, check the (Z912) Ground circuit. NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery. Does the test light illuminate brightly? Yes Replace and program the A/C Heater Control in accordance with the Service Information. Perform the HVAC VERIFICATION TEST. Refer to «HVAC VERIFICATION TEST»(ref-485533-S34738617912012071300000) . No Repair the (Z912) Ground circuit for an open. Perform the HVAC VERIFICATION TEST. Refer to «HVAC VERIFICATION TEST»(ref-485533-S34738617912012071300000) .
7. CHECK THE WIRING AND CONNECTORS The conditions necessary to set the DTC are not present at this time. Using the scan tool, check the Environmental Data to help identify the conditions in which the DTC was set. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension. Wiggle the wiring and connectors while checking for shorted and open circuits. Were there any problems found? Yes Repair as necessary. Perform the HVAC VERIFICATION TEST. Refer to «HVAC VERIFICATION TEST»(ref-485533-S34738617912012071300000) . No Test complete.
