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 the battery.
• Follow all steps 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.
