DESCRIPTION

Occupant Classification System is designed to detect a properly-seated right front occupant and determine if the passenger's frontal airbag should be enabled (may inflate) or not. The system continuously monitors the occupant status and can change the classification decision if there is a change in occupant status.

This bulletin provides the procedure to reset the system's electronic control unit (referred to as "PODS ECU" on the GDS display screen) using the GDS tool. The PODS ECU (which is different from the main SRS Control Module) needs to be reset under the two conditions noted below:

To erase diagnostic codes relating to the PODS ECU.
To reset the PODS ECU after replacing the front passenger seat cover or seat cushion assembly.

NOTE: Failure to perform the "PODS RESET" procedure before erasing the SRS Control Module code(s) can activate the SRS diagnostic code B1489 (PODS ECU Failure).

NOTE: The PODS ECU must be reset after the front passenger seat cushion assembly is replaced.

NOTE: Refer to the Owner's Manual section "Occupant Classification System" or the Service Shop Manual, under the Restraints Section, for details regarding the PODS ECU and diagnosis.

PODS ECU RESET PROCEDURE

The following procedures are to be followed to erase the PODS ECU diagnostic codes and for PODS ECU resetting.

Connect the GDS VCI module to the vehicle's DLC connector and open the GDS program.

Fig 1: Identifying GDS VCI Module
Turn on vehicle ignition and make sure the green power LED is lit on the VCI; if it is not lit press on the power button of the VCI. Within a few seconds, the GDS screen should indicate VCI:USB On in bright blue to the left of the VIN button on the screen.
Press the VIN button at the top of the screen to launch the GDS VIN search screen.

If there are diagnostic codes related to the PODS ECU stored in the main SRS Control Module, the PODS ECU must be reset first before any SRS diagnostic code(s) can be erased. See table below for PODS ECU related codes.

NOTE: Do not clear any SRS diagnostic code(s) at this time. Proceed to the next step.
