Ranger 2WD V6-4.0L (2010)
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.
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 volts and less than 18 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.
Carry out the Occupant Classification Sensor (OCS) system reset.
9. If the first system reset attempt was unsuccessful, carry out a thorough visual inspection of the following and repair any concerns found.
-
OCS system connector and wiring for damage
-
Pressure sensor hose for kinks and/or damage
-
Seat-related wiring harness and body wiring harness terminals and connectors for damage
10. NOTE: The ignition switch must be cycled after the OCS system reset.
Carry out a second OCS system reset. If the second attempt is unsuccessful, install a new OCS system service kit. For additional information, refer
to Occupant Classification System in Restraint Systems.
11. 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 detected, the air bag warning indicator will:
- fail to light.
- remain lit continuously.
- flash.
The flashing might not occur 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 and Occupant Classification System Module (OCSM) using a scan tool.
All seats
12. Check the active restraint system for correct operation. For additional information, refer to Safety Belt System. See: Testing and Inspection
