Powertrain Verification Test VER-5
NOTE:
After repair is complete, perform TRANSMISSION VERIFICATION TEST VER-1 .
NOTE:
If PCM is replaced, correct vehicle mileage and Vehicle Identification Number (VIN) must be programmed into PCM to prevent a DTC from being set in Anti-Lock Brake System (ABS) module, Supplemental Restraint System (SRS) module and SKIM. To program PCM, proceed to appropriate procedure listed below. On models equipped with a Smart Key Immobilizer Module (SKIM), if replacing PCM, secret key data must also be updated to enable engine starting. To update secret key data, proceed to appropriate procedure listed below.
NOTE:
Before replacing PCM for a failed driver, control circuit or ground circuit malfunction, ensure to check related component/circuit integrity for failures not detected due to a double fault within circuit. Most PCM driver/control circuit failures are caused by internal failure to components. These failures are difficult to detect when a double fault has occurred and only one DTC is set.
NOTE:
If PCM and SKIM are replaced at the same time, program VIN into PCM first. All vehicle keys will then need to be replaced and reprogrammed to new SKIM.
NOTE:
The Sentry Key Immobilizer System (SKIS) secret key is an ID code that is unique to each SKIS. This code is programmed and stored in SKIM, engine controller and transponder chip (ignition key). When replacing PCM, it is necessary to program the secret key into PCM.
NOTE:
If 3 attempts are made to enter the secure access mode using an incorrect PIN, secured access mode will be locked out for one hour. To exit this lockout mode, turn ignition switch to RUN position for one hour, then enter the correct PIN. Ensure all accessories are off. Also monitor battery state. Connect a battery charger to battery, if necessary.
- Procedure For Programming PCM
Connect scan tool to DLC. Turn ignition on. Using scan tool, select THEFT ALARM, SKIM, then MISCELLANEOUS. Select PCM REPLACED. Enter secured access mode by entering vehicle 4-digit PIN. Press enter to transfer secret key (SKIM will send secret key to PCM). Go to step 1. - Procedure For Programming SKIM
Connect scan tool to DLC. Turn ignition on. Go to THEFT ALARM, SKIM, and then MISCELLANEOUS. Select SKIM MODULE REPLACEMENT (GASOLINE). Program vehicle 4-digit PIN into SKIM. Select COUNTRY CODE and enter correct country. If incorrect country code is programmed into SKIM, SKIM must be replaced. Select UPDATE VIN (the SKIM will learn VIN from PCM). Press enter to transfer VIN (PCM will send the VIN to the SKIM). Scan tool will ask if you want to transfer the secret key. Select enter to transfer secret key from PCM. This will ensure correct vehicle ignition keys will still operate SKIM system. Go to step 1. - Procedure For Programming Ignition Keys To SKIM
Connect scan tool to DLC. Turn ignition on. Using scan tool, select THEFT ALARM, SKIM, then MISCELLANEOUS. Select PROGRAM IGNITION KEYS. Enter secured access mode by entering vehicle 4-digit PIN. When programming is complete, SKIM will exit SECURED ACCESS mode and display status of key. PROGRAMMING SUCCESSFUL is displayed if SKIM smart key programming succeeds. Go to step 1. If ignition key programming is unsuccessful, one of the following status messages may be displayed as follows:- LEARNED KEY IN IGNITION is displayed if key in the ignition has already been programmed into vehicle's SKIM.
- 8 KEYS ALREADY LEARNED, PROGRAMMING NOT DONE is displayed if 8 keys have already been programmed into SKIM. If a new key needs to be added due to a lost or defective key, the ERASE ALL CURRENT IGN. KEYS function has to be performed. Original 7 keys plus additional new key may then be reprogrammed into SKIM.NOTE: A maximum of 8 keys can be learned to each SKIM at one time. Once a key is learned to a SKIM, it cannot be transferred to another vehicle.
- PROGRAMMING NOT ATTEMPTED is displayed if scan tool attempts to read programmed key status and there are no keys programmed in SKIM memory.
- PROGRAMING KEY FAILED is displayed if SKIM is unable to program key due to faulty ignition key transponder or ignition key is programmed to another vehicle.
- Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. If any DTCs have not been diagnosed, return to appropriate test(s). If all DTCs have been diagnosed and repaired, go to next step.
- Connect scan tool to DLC, if necessary. Ensure fuel tank is at least 1/4 full. Ensure all accessories are off. Go to next step.
- Proper way to ensure DTC is repaired is to allow PCM to run monitor. Monitor operation may be observed on scan tool. All specified enabling conditions for specified DTC must be met before PCM will operate monitor. Go to next step.
- Using scan tool, monitor pretest enabling conditions until all conditions have been met. Once all enabling conditions are met, observe appropriate monitor for DTC on scan tool. If repaired DTC has reset or is seen in monitor while on road test, repair is not complete. Check for related Technical Service Bulletins (TSBs) or flash updates and return to appropriate test. If no DTCs return, go to step 6.
- If another DTC exists, return to appropriate test(s). If no DTCs return, go to next step.
- Turn ignition on, with engine off. Using scan tool, erase DTCs. Turn ignition off. Disconnect scan tool. Test is complete.
