IMMU : CONSULT Function (BCM - IMMU)

INFOID:0000000009764047

CAUTION:

After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must

be cycled OFF 

→ ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go

to ”sleep mode”, potentially causing a discharged battery and no-start condition.
