64 04 25_SERVICE ACTION: MODIFY HARNESS ROUTING AT THE NEXT NANOFILTER REPLACEMENT

Cabin Air Microparticle Nanofilter - Maintenance Replacement IntervalsInternal Combustion Engine Vehicle (ICEV)
Plug-In Hybrid Electric Vehicle (PHEV)
Battery Electric Vehicle (BEV)

Every 2nd engine oil service (approx. 20,000 mi)
Every 2nd engine oil service (approx. 20,000 mi)
Every Vehicle Check (approx. every 24 months)

CAUSE
When servicing the cabin air microparticle nanofilter, it is possible to pinch and thereby damage the vehicle’s
wiring harness while re-installing the retaining screws for the cabin air nanofilter’s plastic cover.
To help prevent this type of damage to the wiring harness, install a new retention strap for the harness the
next time an Affected Vehicle is at the workshop for a cabin air filter maintenance service.

CORRECTION
Use caution when re-installing the plastic cover for the cabin air filter to ensure no damage is done to the
vehicle’s wiring harness.
Add a retainer to the harness to prevent it being
pinched under the air filter plastic cover.

PROCEDURE
When following Repair Instructions REP 64 31
010 to change the cabin air nanofilter, check the
vehicle wiring harness routing (circled) before
fastening the plastic cover over the filter.

64 04 25_SERVICE ACTION: MODIFY HARNESS ROUTING AT THE NEXT NANOFILTER REPLACEMENT

Double check the routing of the harness prior to
installing the screws for the cabin air filter cover.
If the wiring harness has already been damaged
during the installation of the cabin air filter cover,
the damaged section of the wiring harness must
be repaired.

The original harness retainer must be disconnected. This is shown by the red arrow below. It can be
left clipped into vehicle but must be disconnected from harness for strain relief.
Install a new harness retainer with cable strap on the Instrument Panel wiring harness, see green
arrow.
