Mustang V8-4.6L (2009)
10. Install the front seat.
11. Repower the SRS. For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering See: Air Bag(s)
Arming and Disarming/Service and Repair/Supplemental Restraint System (SRS) Depowering and Repowering in the General Procedures.
12. 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 8.0 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 procedure. 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 carrying out the OCS system reset
process.
For passenger seat, Carry out the OCS system reset. If the system reset was successful, proceed to Step 16, otherwise proceed to Step 13.
13. If the first system reset attempt was unsuccessful, carry out a thorough visual inspection of the following:
-
OCS system wiring
-
Check the pressure sensor hose for kinks and/or damage
-
Related seat wiring harness, body wiring harness terminals and connectors
14. If the damage is found, repair and/or install new components as necessary.
15. Carry out a second OCS system reset. If the second attempt is unsuccessful, install a new OCS system service kit.
16. NOTE: The ignition switch must be cycled after the OCS system reset.
Prove out the SRS as follows:
Turn the ignition switch from ON to OFF. Wait 10 seconds, then turn the ignition switch 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.
17. 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).
