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.
CAUTION:
-
Make sure the seat is completely assembled before carrying out the OCS system reset active command. Failure to follow these
instructions may result in incorrect operation of the OCS system and system failure.
-
The following precautions must be taken before carrying out the occupant classification sensor (OCS) system reset:
-
Make sure the OCS system components are connected and no faults are present.
-
Make sure the voltage to the occupant classification sensor module (OCSM) is above 8.0 volts and less then 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 4-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 occupant classification sensor (OCS) system reset is unsuccessful or DTC C1941 is reported, a second
attempt must be made. If the second attempt to carry out the OCS system reset is unsuccessful or DTC C1941 is reported a second time, a new
OCS service kit must be installed.
8. Carry out the OCS system reset.
-
With the front passenger seat empty, use a IDS or equivalent tester to trigger the active command.
All seats
NOTE: The ignition switch must be cycled after the OCS system reset.
9. 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 air bag SRS
fault is present, the air bag warning indicator will:
-
fail to light.
-
remain lit continuously.
-
flash at a 5 Hz rate (RCM not configured).
The air bag warning indicator might not light until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON
position. This is the time required fro the RCM to complete the 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 OCSM DTCs using the integrated diagnostic system (IDS) or equivalent tester.
10. Check the active restraint system for correct operation.
