Mil Check: Notes
NOTE:
When Powertrain Control Module (PCM) connectors are disconnected, all Diagnostic Trouble Codes (DTCs) will be erased. It is necessary to use VAG 1598 test box to perform procedures.
NOTE:
It is necessary to generate a PCM readiness code if PCM memory is cleared, battery voltage is disconnected or PCM is disconnected. See CLEARING CODES
under SELF-DIAGNOSTIC SYSTEM.
NOTE:
MIL check should only be performed if MIL is on continuously and no DTCs are stored or MIL never illuminates.
