DTC Descriptor

DTC 063
- PPS Out of Calibration

Circuit/System Description

The Passenger Presence Module is used to monitor the weight of an occupant in the front passenger seat. The Passenger Presence Module is calibrated at the seat assembly plant and cannot be recalibrated at a service center and must be replaced. The Passenger Presence Module continuously monitors itself and if the system becomes out of calibration, DTC 063 will be set. When the Passenger Presence Module detects this DTC within the Passenger Presence Module, it will notify the customer of the enable/disable status by illuminating the OFF indicator on the PASSENGER AIR BAG ON/OFF indicators. Then the Passenger Presence Module will communicate to the Inflatable Restraint Sensing and Diagnostic Module through a non-class 2 communications circuit that a Passenger Presence Module fault is present. The Inflatable Restraint Sensing and Diagnostic Module will then set DTC B0092 indicating a problem within the Passenger Presence Module and will suppress the deployment of the passenger instrument panel air bag and then illuminate the AIR BAG indicator.

Conditions for Running the DTC

Ignition voltage is between 9-16 volts.

Action Taken When the DTC Sets

* The Passenger Presence Module will set a DTC, and then communicate with the Inflatable Restraint Sensing and Diagnostic Module.

* The Inflatable Restraint Sensing and Diagnostic Module will set DTC B0092.

* The Inflatable Restraint Sensing and Diagnostic Module disables the passenger instrument panel air bag deployment loop.

* The Passenger Presence Module will illuminate the passenger air bag status OFF indicator.

* The Inflatable Restraint Sensing and Diagnostic Module requests the Instrument Cluster to illuminate the AIR BAG indicator.

Conditions for Clearing the DTC

DTC 063 is an indication that Passenger Presence Module is out of calibration. You cannot recalibrate the Passenger Presence Module. Replace the Passenger Presence Module after following the instructions in the Circuit/System Testing.

Diagnostic Aids

The presence of current or history DTCs while attempting to rezero the Passenger Presence Module will cause the Passenger Presence Module to set DTC 063. Verify that all SIR and Passenger Presence Module DTCs have been cleared before rezeroing the Passenger Presence Module.
