BODY VERIFICATION TEST - VER 1 APPLICABILITY
1. Disconnect all jumper wires and reconnect all previously disconnected components and
connectors.
2. With the DRBIIIt, record and erase all DTCs from ALL modules. Cycle the ignition on then
off
3. If the Sentry Key Immobilizer Module (SKIM), the Powertrain Control Module (PCM), or the
Engine Control Module (ECM) was replaced, proceed to number 9. If the SKIM, PCM, or ECM
was not replaced, continue to the next number.
4. If the Body Control Module (BCM) was replaced, turn the ignition on for 15 seconds (to allow
the new BCM to learn VIN) or engine may not start (if VTSS equipped). If the vehicle is
equipped with VTSS, use the DRBIIItand enable VTSS.
5. Program all other options as needed.
6. If any actuators were replaced in the HVAC System, with the DRBIIItin HVAC, select
System Tests then select HVAC Door Recalibration (manual temperature system only).
7. If any actuators were replaced in the ATC System, with the DRBIIItin Automatic Temp
Control, select Miscellaneous then select Reset ATC Head.
8. If any repairs were made to the power sliding door or power liftgate, use the DRBIIItand
perform the open and close system tests. Observe the instructions on the DRBIIItscreen.
Proceed to number 16.
9. Obtain the vehicle's unique PIN assigned to it's original SKIM from either the vehicle's
invoice or from Chrysler's Customer Assistance Center (1-800-992-1997).
10. NOTE: Once Secured Access Mode is active, the SKIM will remain in that mode for 60
seconds.
11. With the DRBIIIt, select THEFT ALARM, SKIM, MISCELLANEOUS and select SKIM
REPLACED. Enter the 4 digit PIN to put the SKIM in Secured Access Mode.
12. The DRBIIItwill prompt for the following steps. (1) Program the country code into the
SKIM's memory. (2) Program the vehicle's VIN into the SKIM memory. (3) Transfer the
vehicle's Secret Key data from the PCM.
13. Using the DRBIIIt, program all customer keys into the SKIM memory. This requires that
the SKIM be in Secured Access Mode, using the 4 digit PIN.
14. Note: If the PCM or ECM is replaced, the VIN and the unique Secret Key data must be
transferred from the SKIM to the PCM or ECM. This procedure requires the SKIM to be placed
in Secured Access Mode using the 4-digit PIN.
15. Note: If 3 attempts are made to enter Secured Access Mode using an incorrect PIN, Secured
Access Mode will be locked out for 1 hour which causes the DRBIIItto display9No Resp from
SKIM9. To exit this mode, turn ignition to Run for 1 hour.
16. Ensure that all accessories are turned off and the battery is fully charged.
17. Start and run the engine for 2 minutes. Operate all functions of the system that caused the
original concern.
18. Turn the ignition off and wait 5 seconds. Turn the ignition on and using the DRBIIIt, read
DTCs from ALL modules.
Are any DTC's present or is the original condition still present?All
Ye s®Repair is not complete, refer to the appropriate symptom.
