Mustang V6-4.0L (2008)
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 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 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.
16. Cycle the ignition switch from ON to OFF.
17. NOTE: The ignition switch must be cycled after the OCS system reset.
Cycle the ignition switch from OFF to ON.
18. 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.
19. NOTE: A prepaid return postcard is provided with a new OCS system service kit. The serial number for the new part and the vehicle
identification number (VIN) must be recorded and sent to Ford Motor Company.
If a new OCS system service kit was installed, fill out the necessary information on the OCS system traceability card and return it along with the
complete inoperative OCS system to Ford Motor Company.
-
When returning the inoperative OCS system include: seat cushion foam pad, bladder, OCSM, pressure sensor (transducer), hose, electrical
connectors and wire harness (service part OCS only).
