NOTE: Ensure that the refrigerant system is properly charged. Refer to the
appropriate Service Information.
Turn the ignition on.
With the DRBIII
t, actuate the A/C Clutch Relay.
Is the A/C Clutch actuating?
All
Yes
→ The A/C Clutch System operating properly at this time.
Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC.
No
→ Go To 2
2
Turn the ignition off.
Disconnect the A/C Clutch harness connector.
Measure the (Z1) Ground circuit in the A/C Clutch harness connector to ground.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 3
No
→ Repair the (Z1) Ground circuit for an open.
Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC.
3
Disconnect the A/C Clutch harness connector.
Turn the ignition on.
With the DRBIII
t, actuate the A/C Clutch Relay.
Measure the voltage of the A/C Clutch Relay Output circuit in the (C3) A/C Clutch
harness connector.
Is the voltage above 11.0 volts?
All
Yes
→ Replace the A/C Clutch.
Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC.
No
→ Go To 4
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?
All
Yes
→ Go To 5
No
→ Repair the (A17) Fused B+ circuit. Inspect fuses and replace as
necessary.
Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC.

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?
All
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.

Symptom List:
ANTENNA FAILURE
COP FAILURE
EEPROM FAILURE
INTERNAL FAULT
RAM FAILURE
SERIAL LINK INTERNAL FAULT
STACK OVERFLOW FAILURE
Test Note:
All symptoms listed above are diagnosed using the same tests.
The title for the tests will be ANTENNA FAILURE.
When Monitored and Set Condition:
ANTENNA FAILURE
When Monitored:
Every 250 milliseconds with the ignition on.
Set Condition:
The SKIM’s microcontroller determines that an antenna circuit fault has
occurred for 2.0 consecutive seconds.
COP FAILURE
When Monitored:
With the ignition on.
Set Condition:
The COP timer is not reset by the micro controller every 65.5 milliseconds.
EEPROM FAILURE
When Monitored:
With the ignition on.
Set Condition:
When the value written to EEPROM memory does not equal the value
read back after the write operation.
INTERNAL FAULT
When Monitored:
With the ignition on.
Set Condition:
The SKIM has detected a fault during an internal self test.
RAM FAILURE
When Monitored:
With the ignition on.
Set Condition:
The RAM fails a test that checks the RAM’s ability to retain memory.
SERIAL LINK INTERNAL FAULT
When Monitored:
With the ignition on.
Set Condition:
The SKIM fails an internal J1850 communication self test.
STACK OVERFLOW FAILURE
When Monitored:
With the ignition on.
Set Condition:
The micro controller has exceeded its stack space limit.

SENTRY KEY IMMOBILIZER
POSSIBLE CAUSES
SKIM INTERNAL DTC FAILURE
TEST
ACTION
APPLICABILITY
1
Note: This trouble code indicates an internal SKIM fault.
With the DRBIII
t, read and record the SKIM DTCs and then erase the SKIM DTCs
Perform 5 ignition key cycles, leaving the ignition key on for a minimum of 90 seconds
per cycle.
With the DRBIII
t , read the SKIM DTCs.
Did the same SKIM DTC return?
All
Yes
→ Replace and program the Sentry Key Immobilizer Module in
accordance with the Service Information.
Perform SKIS VERIFICATION.
No
→ Test Complete.
