Mustang V6-4.0L (2008)
-
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:
-
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 trim cover installed or an OCS system service kit is installed. A scan tool is used to carry out the
OCS system reset command.
-
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 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 occupant classification sensor (OCS) system reset is unsuccessful, a second attempt must be made. If the
second attempt is unsuccessful, a new OCS system service kit must be installed.
Carry out the OCS system reset active command.
17. Cycle the ignition switch from ON to OFF.
18. NOTE: The ignition switch must be cycled after the OCS system reset.
Cycle the ignition switch from OFF to ON.
All seats
19. 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 5Hz 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 for 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 continuous DTCs from the RCM using a scan tool.
