Connect a fully charged jumper battery to the vehicle, and leave it connected during the entire procedure to maintain steady voltage. Do not use the GR8 because the vehicle requires a steady electrical current. Control module failure caused by the improper completion of a software update (early key cycle, low battery voltage, disconnected DLC cable, etc.) is not covered by warranty. If an error occurs during the update or the i-HDS freezes, do not disconnect the battery or turn the ignition to OFF. Reboot the i-HDS, and start over. To prevent control unit damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power windows, door locks, etc.) during the update. Warranty reimbursement for technician labor is not allowed for routine checking/installation of any available software update. NOTE This update will not require entering a service bulletin number. 1. Update the PCM software using the J2534 Rewrite software with the DST-i. Refer to service bulletin 01-026, Updating Control Units/Modules. 2. California residents only: Fill out a Vehicle Emissions Recall – Proof of Correction certificate, and use A8E as the recall number. Have the service advisor give the certificate to your customer, and advise him or her to keep it as proof that the recall was completed. Your customer will need to submit this certificate to the DMV only if the DMV requests it. If you need more certificates, use reorder number Y0657. END Page 3 of 3
