NOTE: This DTC could have been set if the SKIM harness connector was
disconnected, or if the SKIM was replaced recently.
NOTE: All keys that the customer uses for this vehicle must be tested to
verify they are operating properly.
NOTE: Ensure the customer is not attempting to use a non-SKIM duplicate
key.
Turn the ignition on.
Verify the correct VIN is programmed into the PCM and SKIM.
Turn the ignition off.
With the next customer key turn the ignition key on and crank the engine to start.
With the DRBIII

t, read the PCM DTCs. Look for P1685

Is the Starts Since Set counter for DTC P1685 displayed and equal to 0?

All

Yes

→ Replace the Ignition Key.

Perform SKIS VERIFICATION.

No

→ Test Complete.

NOTE: If this DTC cannot be reset, it could have been an actual theft
attempt.

TEST

ACTION

APPLICABILITY

1

Turn the ignition on.
With the DRBIII

t, read the PCM DTCs. Look for P1686.

Is the Starts Since Set counter on the DTC screen for P1686 equal to Zero?

All

Yes

→ Go To 2

No

→ Go To 5

2

Turn the ignition on.
With the DRBIII

t, attempt to communicate with the SKIM.

NOTE: This test will indicate if the Bus is operational from the DLC to the
SKIM.
Was the DRBIII

t able to communicate with the SKIM?

All

Yes

→ Go To 3

No

→ Refer to symptom BUS +/- SIGNAL OPEN FROM SKIM in the

COMMUNICATION category.
Perform SKIS VERIFICATION.

3

Turn the ignition off.
Disconnect the PCM harness connectors.
Disconnect the SKIM harness connector.
Measure the resistance of the PCI Bus circuit between the PCM harness connector
and the SKIM harness connector.
Is the resistance below 5.0 ohms?

All

Yes

→ Go To 4

No

→ Repair the PCI Bus circuit between the PCM and the SKIM for an

open.
Perform SKIS VERIFICATION.

WARNING: KEEP CLEAR OF THE ENGINE’S MOVING PARTS.
NOTE: The conditions that set the DTC are not present at this time. The
following list may help in identifying the intermittent condition.
With the engine running and at normal operating temperature, monitor the DRBIII

t

parameters related to the DTC while wiggling the wiring harness. Look for param-
eter values to change and/or a DTC to set.
Review the DTC When Monitored and Set Conditions. If possible, try to duplicate the
conditions under which the DTC was set.
Refer to any Technical Service Bulletins (TSB) that may apply.
Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or
partially broken wires.
Visually inspect the related wiring harness connectors. Look for broken, bent, pushed
out, or corroded terminals.
Were any of the above conditions present?

All

Yes

→ Repair as necessary
