Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before installa-

DRIVER AIR BAG MODULE
Tighten the TORX bolts after completely adjusting the centers of fixing holes on the driver air bag
module side and the steering wheel side. If the holes are misaligned, the bolt threads are damaged
and the module is not installed securely.
In the case that a malfunction is detected by the air bag warning lamp, after repair or replacement of
the malfunctioning parts, reset the memory by self-diagnosis or by CONSULT-III.
After the work is completed, check that no system malfunction is detected by air bag warning lamp.
