DIAGNOSTIC PROCEDURES - CHECKING THE A/C RELAY OUTPUT
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 |
NOTE:
Ensure that the refrigerant system is properly charged. Refer to the appropriate Service Information. Turn the ignition on.With the DRBIII®, actuate the A/C Clutch Relay.Is the A/C Clutch actuating?Yes --> The A/C Clutch System operating properly at this time.Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC .No --> Go To 2 |
All |
| 2 | Turn the ignition off. Disconnect the A/C Clutch harness connector. Measure the Ground circuit in the A/C Clutch harness connector to ground. Is the resistance below 5.0 ohms? Yes --> Go To 3 No --> Repair the Ground circuit for an open. Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC . |
All |
| 3 | Disconnect the A/C Clutch harness connector. Turn the ignition on. With the DRBIII®, actuate the A/C Clutch Relay. Measure the voltage of the A/C Clutch Relay Output circuit in the A/C Clutch harness connector. Is the voltage above 11.0 volts? Yes --> Replace the A/C Clutch. Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC . No --> Go To 4 |
All |
| 4 | Turn the ignition off. Remove the A/C Clutch Relay from the PDC. Using a 12-volt test light connected to ground, probe the (A17) Fused B+ circuit in the PDC. Does the test light illuminate brightly? Yes --> Go To 5 No --> Repair the (A17) Fused B+ circuit. Inspect fuses and replace as necessary. Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC . |
All |
| 5 | Turn the ignition off. Disconnect the A/C Clutch Relay from the PDC. Disconnect the A/C Clutch harness connector. Measure the resistance of the (C3) A/C Clutch Relay Output circuit between the PDC and the A/C Clutch harness connector. Is the resistance below 5.0 ohms? Yes --> Replace the A/C Clutch Relay. Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC . No --> Repair the (C3) A/C Clutch Relay Output circuit for an open. Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC . |
