8. 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 sensor (OCS) system and increases the risk of serious
personal injury or death in a crash.
NOTICE: 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
process. 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 the carrying out the OCS system reset
process.
Carry out the OCS System Reset.
If system reset was successful, proceed to Step 11.
If system reset was unsuccessful, proceed to next step.

-
OCS system connector wiring for damage
-
Pressure sensor hose for kinks and/or damage
-
Seat-related wiring harness and body wiring harness terminals and connectors for damage
10. Carry out a second OCS system reset. If the second attempt is unsuccessful, install a new OCS system service kit. For additional information, refer
to Occupant Classification Sensor (OCS) in the Removal and Installation portion of Air Bag Systems.
11. Prove out the SRS as follows:
Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually 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 SRS fault is
present, the air bag warning indicator will:
-
fail to light.
-
remain lit continuously.
-
flash at a 5Hz rate (RCM not configured).
The air bag warning indicator may not illuminate until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON
position. This is the time required for the RCM to complete the testing of the SRS. If the air bag warning indicator is inoperative and a SRS fault
