TEST
3 Turn the ignition off.
Remove the A/C Clutch Relay from the PDC.
Measure the resistance of the A/C Clutch Relay between the Fused Ignition Switch
Output terminal and the A/C Clutch Relay Control terminal.
Is the resistance between 60 to 95 ohms?
Yes → Go To 4
→ Replace the A/C Clutch Relay.
No
4 Turn the ignition off.
Remove the A/C Clutch Relay from the PDC.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the (C28) A/C Clutch Relay Control circuit from the PDC
to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
Yes → Go To 5
→ Repair the open in the (C28) A/C Clutch Relay Control circuit.
No
5 Turn the ignition off.
Remove the A/C Clutch Relay from the PDC.
Measure the resistance between ground and the (C28) A/C Clutch Control circuit in
the PDC.
Is the resistance below 5.0 ohms?
Yes → Repair the short to ground in the (C28) A/C Clutch Relay Control
→ Go To 6
No
6 NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
If there are no possible causes remaining, view repair.
