Ignition System

Ignition System

• The ignition must be turned off when disconnecting the battery. Obtain the radio code for radios with a anti-theft code before disconnecting battery.

• Observe required safety precautions after connecting the battery.

• For trouble-free operation of the electrical components a voltage of at least 11.5 volts is necessary.

• To complete the procedure, check the Engine Control Module (ECM) Diagnostic Trouble Code (DTC) memory and erase any DTCs that may have been stored when testing and making repairs. If the DTC memory was erased, the readiness code must be generated again. Refer to "Guided Fault Finding" in the vehicle diagnostic tester.

• If the engine only starts briefly and then shuts off again after troubleshooting, repair or checking of the components, it may be that the immobilizer is blocking the ECM. The control module may have to be adapted then. Refer to "Guided Functions" in the vehicle diagnostic tester.
