DTC 1052
DTC 1052, 1053, 1054, 1055, 1056, or 1057
Circuit Description
The passenger presence system (PPS) is divided up into 6 regions. When there is an unwanted force being applied to one or more PPS regions, the PPS will set a diagnostic trouble code (DTC). If the PPS detects any preload DTC within the PPS, then the PPS will communicate to the SDM through a non class 2 communications circuit that a PPS fault is present. The SDM will then set DTC B0092 indicating a problem within the PPS.
DTC Descriptors
This diagnostic procedure supports the following DTCs:
* DTC 1052 PPS Preload Failure Region 1
* DTC 1053 PPS Preload Failure Region 2
* DTC 1054 PPS Preload Failure Region 3
* DTC 1055 PPS Preload Failure Region 4
* DTC 1056 PPS Preload Failure Region 5
* DTC 1057 PPS Preload Failure Region 6
Conditions for Running the DTC
Ignition 1 voltage is within the normal operating voltage range.
Conditions for Setting the DTC
The PPS will set a DTC when a region has detected a preload/pressure on it, refer to the table below for specific region.
Action Taken When the DTC Sets
* The PPS will set a DTC then communicate with the SDM via non Class 2 circuit.
* The SDM will set DTC B0092.
* The SDM disables the instrument panel (I/P) module deployment loop.
* The SDM commands the AIR BAG indicator ON via Class 2 serial data.
Conditions for Clearing the DTC
* The condition responsible for setting the DTC no longer exists.
* You issue a scan tool CLEAR DTCs command.
* A history DTC will clear once 255 malfunction-free ignition cycles have occurred.
Diagnostic Aids
When passenger seat bottom trim cover is serviced or removed, the trim cover, when reinstalled may apply certain unwanted pressure to the PPS causing DTC 1052-1057 to set.
