7. WARNING:
-
Install a new occupant classification sensor (OCS) system service kit as a complete assembly. Never install only part of the kit
components. Failure to follow this instruction may result in incorrect operation of the OCS system and increases the risk of serious
personal injury or death in a crash.
-
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.
CAUTION:
-
It is necessary to carry out the occupant classification sensor (OCS) system reset when a front passenger seat cushion is disassembled,
a new trim cover is installed or an OCS system service kit is installed. A scan tool is used to carry out the OCS system reset command.
Failure to follow this instruction may result in system failure and the incorrect operation of the OCS system.
-
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 8.0 volts and less than 18.0 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 switch ON before the carrying out the OCS
system reset process.
NOTE: If the first attempt to carry out the OCS system reset is unsuccessful, a second attempt must made. If the second attempt to carry out the OCS
system reset is unsuccessful, a new OCS system service kit must be installed.
Carry out the OCS system reset command using the scan tool.
8. Cycle the ignition switch from ON to OFF.
9. NOTE: The ignition switch must be cycled after the OCS system reset.
Cycle the ignition switch from OFF to ON.

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 air bag SRS
fault is present, the air bag warning indicator will:
-
fail to light.
