i
Verify Vehicle Identification Number (VIN)
on vehicle VIN markings matches VIN on
Repair Order exactly. Correct VIN errors
on RO before RO is closed at your
dealership.

p
A sufficient power supply to the
vehicle on-board system must be
ensured throughout the entire work
procedure.
Otherwise any undervoltage that
occurs may damage the control
units.
i
Do not connect the battery charger to
the auxiliary battery in the engine
compartment.
i
Follow the operating instructions for

Pre-existing faults causing a Check Engine
Light must be evaluated. Reference PreInspection Notes on page 2.

i
The diagnostic system remains connected to
the vehicle throughout the work procedure!
Do not disconnect the diagnostic system’s
online connection.
