If the Electric Drive Power and Control Electronics -JX1- is replaced, always complete the following adaptations in the order listed:
1. Adapt the Electric Drive Power and Control Electronics -JX1- to the immobilizer using the Vehicle Diagnostic Tester.
2. Code the Electric Drive Power and Control Electronics -JX1- using the Vehicle Diagnostic Tester.
3. Calibrate the Electro-Drive Drive Motor -V141- using the Vehicle Diagnostic Tester.
The Electro-Drive Drive Motor -V141- will automatically calibrate at the end of "Guided Fault Finding" once all Diagnostic Trouble Code (DTC) entries are erased.
The "calibration" must be performed each time the DTC memory for the Electric Drive Power and Control Electronics -JX1-, Battery Regulation Control Module -J840-, engine or transmission is "erased". Otherwise the vehicle will only start after the second try.
