Diagnostic Test

TPM

Was the WCM/SKREEM replaced during the test procedure?

Yes

>> Go to 2

>> Go to 3

WCM/SKREEM

NOTE: When entering the PIN, care should be taken because the SKREEM will only allow three consecutive
attempts to enter the correct PIN. If three consecutive incorrect PIN’s are entered the SKREEM will Lock Out
the scan tool. To exit Lock Mode, the ignition key must remain in the Run position for one hour. All acces-
sories must be off. A battery charger connected to the battery during this time period is recommended.

1. Reconnect the previously removed and/or disconnected components and connectors.

2. Obtain the vehicle’s unique Personal Identification Number (PIN) assigned to it’s original SKREEM. This num-
ber can be obtained from the vehicle invoice or from the DaimlerChrysler Customer Center (Phone 1-800-992-
1997).

3. With the scan tool, select Miscellaneous Functions, WCM/Wireless Control Module. Then select the desired
procedure and follow the display on the scan tool.

4. If the WCM/SKREEM was replaced, all the customer’s keys must be programmed to the new module. Use the
scan tool and the Program Key procedure

5. With the scan tool, erase all DTCs. Perform 5 ignition key cycles, leaving the key on for at least 90 seconds
per cycle.

6. Drive the vehicle for a minimum of 10 minutes while maintaining a continuous speed above 15 mph (24 km/h).
During this time the system will learn the new sensor ID code and will clear any DTC(s) automatically.

7. With the scan tool, read WCM/SKREEM DTC(s).

Are there any DTC(s) present?

Yes

>> Repair not complete, refer to the appropriate symptom.

>> Repair is complete.

TIRE PRESSURE SENSOR/TIRE PRESSURE TRANSPONDER REPLACE

1. Reconnect the previously removed and/or disconnected components and connectors.

2. Drive the vehicle for a minimum of 10 minutes while maintaining a continuous speed above 15 mph (24 km/h).
During this time the system will learn the new sensor ID code and will clear any DTC(s) automatically.

3. With the scan tool, read TPM DTC(s).

Are there any DTC(s) present?

Yes

>> Repair not complete, refer to the appropriate symptom.
