TEST ACTION APPLICABILITY
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?
All
Yes → Go To 4
No → Replace the A/C Clutch Relay.
Perform POWERTRAIN VERIFICATION TEST VER-2-NGC.
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?
All
Yes → Go To 5
No → Repair the open in the (C28) A/C Clutch Relay Control circuit.
Perform POWERTRAIN VERIFICATION TEST VER-2-NGC.
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?
All
Yes → Repair the short to ground in the (C28) A/C Clutch Relay Control
circuit.
Perform POWERTRAIN VERIFICATION TEST VER-2-NGC.
No → Go To 6
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.
All
Repair
Replace and program the Powertrain Control Module Module in
accordance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER-2-NGC.
