Note
All Passenger Presence System (PPS) modules that are replaced should include documentation of ALL PPS DTCs and repair description in the R.O. in
the warranty claim system. PPS DTCs are read by counting the number of On/Off indicators flashes on the passenger airbag display located above the
radio.
Important
Technicians are to use the Passenger Presence System Flash Code procedure in SI to correctly diagnose the problem. If the PPS DTC is in history (PPS
indicator will flash codes only once), make note of the DTC on the R.O., clear codes and return the vehicle to the customer. If the PPS DTC is an active
fault (PPS indicators will flash same codes twice), make note of the DTC on the R.O. and follow the troubleshooting codes below.
