with Passive / Keyless Entry System (RPO ATH)

Supersession Statement:

This PI was superseded to update model years. Please discard PIC5852B.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

CONDITION / CONCERN

A customer may comment that all of their fob functions work properly, opening trunk, locking or unlocking doors, but all of the passive features are inoperative, when attempting to start vehicle "No Fob Detected" message is displayed. If the fob is placed in the pocket the vehicle will start.

RECOMMENDATIONS / INSTRUCTIONS

It is possible the vehicle may have been shipped with or a dealer mistakenly added a "non-PEPS" fob to a "PEPS" (Passive Entry Passive Start) vehicle. This can be confirmed by obtaining the part number from the body of the fob behind the key blade and comparing to the Electronic Parts Catalog (EPC).

An alternate method would be to remove the battery cover and battery from the fob. With the blade of the key at 12 o'clock, look at the printed circuit board.

A non-PEPS fob (right) will have words stamped on the circuit board at the 3 o'clock position. A PEPS fob (left) will have a stamping at the 6 o'clock position.

Replace the effected fob as required.
