Disconnect the PCM harness connector.
Measure the resistance across the IAC Motor harness connector.
Is the resistance below 5.0 ohms?

All

Yes

→ Repair the (K961) IAC Return circuit short to the (K61) IAC

Motor Control circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.

No

→ Go To 6

ACTION

APPLICABILITY

1

Turn the ignition on.
With the DRBIII

t, read the PCM DTCs.

Is the Good Trip Counter displayed and equal to zero?

All

Yes

→ Go To 2

No

→ Go To 7

2

With the DRBIII

t, attempt to communicate with the SKREEM.

Turn the ignition on.
Can the DRBIII

t communicate with the SKREEM?

All

Yes

→ Go To 3

No

→ Refer to the No Communication category.

Perform SKREEM VERIFICATION TEST - VER 1A.

3

Turn the ignition on.
With the DRBIII

t, check for SKREEM DTCs.

Are any DTCs present in the SKREEM?

All

Yes

→ Refer to SKREEM category for the related symptom(s).

Perform SKREEM VERIFICATION TEST - VER 1A.

No

→ Go To 4

4

Turn the ignition on.
With the DRBIII

t, display the VIN that is programmed in the PCM.

Has a VIN been programmed into the PCM?

All

Yes

→ Go To 5

No

→ Program the correct VIN into the PCM and retest.

Perform SKREEM VERIFICATION TEST - VER 1A.
