System Reset - Bladder System

WARNING: Make sure the front passenger seat repair is complete, the seat and all attached components (head restraint, seat side shield, etc.) are correctly assembled, and the seat is correctly installed to the vehicle before carrying out the System Reset. Failure to follow these instructions may result in incorrect operation of the occupant classification system (OCS) and increases the risk of serious personal injury or death in a crash.

NOTE: To prevent system failure, it is necessary to carry out the Occupant Classification Sensor (OCS) system reset when a front passenger seat cushion is disassembled, a new cover installed or an OCS system service kit is installed. A scan tool is used to carry out the OCS system reset.

NOTE: To prevent system failure, the following precautions must be taken before carrying out the Occupant Classification Sensor (OCS) system reset:

Make sure the voltage to the Occupant Classification System Module (OCSM) is above 8 volts and less than 18 volts.
Make sure the OCS system is not at a temperature below 6°C (42°F) or above 36°C (97°F) when initiating the OCS system reset. If the vehicle has been exposed to extreme cold or hot temperatures, the vehicle must be exposed and kept at a temperature within the limits, 6°C to 36°C (42°F to 97°F) for a minimum of 30 minutes.
Make sure nothing is present on the passenger seat before carrying out the OCS system reset and nothing is placed on the seat during the process.
Make sure a minimum 8-second time period has passed after cycling the ignition ON before carrying out the OCS system reset.

NOTE: An Occupant Classification Sensor (OCS) system service kit has the electrical connector glued to the Occupant Classification System Module (OCSM). It cannot and should not be disconnected or altered.

NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.

Make sure no OCSM DTCs are present. If DTC C1941 is the only OCSM present, it will clear upon a successful system reset. All other OCSM DTCs must be diagnosed and repaired before carrying out the OCS system reset.
Carry out the OCS system reset.
If the first system reset attempt was unsuccessful, carry out a thorough inspection of the following and repair any concerns found.
- OCS system connector and wiring for damage
- Pressure sensor hose for kinks and/or damage
- Seat-related wiring harness and body wiring harness terminals and connectors for damage
Carry out a second OCS system reset. If unsuccessful, install a new OCS system service kit. For additional information, REFER to Occupant Classification Sensor .
Prove out the SRS as follows:
Turn the ignition from ON to OFF. Wait 10 seconds, then turn the ignition ON and monitor the air bag warning indicator with the air bag modules installed. The air bag warning indicator will light continuously for approximately 6 seconds and then turn off. If an air bag SRS fault is detected, the air bag warning indicator will:
- fail to light.
- remain lit continuously.
- flash.
The flashing might not occur until approximately 30 seconds after the ignition has been turned from the OFF to the ON position. This is the time required to complete testing of the SRS. If the air bag warning indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of 5 sets of 5 beeps. If this occurs, the air bag warning indicator and any SRS fault discovered must be diagnosed and repaired.

Clear all RCM and OCSMCMDTCs.
