PCM

TEST

ACTION

APPLICABILITY

Turn the ignition on.
With the DRBIII

t, actuate the A/C Clutch Relay.

Is the A/C Clutch Relay operating?

All

Yes

→ Go To 2

→ Go To 3

Turn the ignition on.
With the DRBIII

t, actuate the A/C Clutch Relay.

Wiggle the wiring harness from the A/C Clutch Relay to the PCM while the relay is
actuating.
Did the A/C Clutch Relay stop when wiggling the wiring harness?

All

Yes

→ Repair as necessary.

Perform POWERTRAIN VERIFICATION TEST VER - 5.

→ Refer to the INTERMITTENT CONDITION symptom in the

Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER - 5.

TEST

ACTION

APPLICABILITY

Turn the ignition off.
Remove the A/C Clutch Relay from the IPM.
Turn the ignition on.
Using a 12-volt test light connected to ground, probe the Fused Ignition Switch
circuit in the IPM.
Does the test light illuminate?

All

Yes

→ Go To 4

→ Go To 9

Turn the ignition off.
Remove the A/C Clutch Relay from the IPM.
Turn the ignition on.
Using a 12-volt test light connected to 12-volts, probe the A/C Clutch Relay circuit in
the IPM.
