Mariner 4WD L4-2.5L (2010)
Connect the electrical connector(s) and wiring clips in the following sequence.
1. Connect the seat wire harness OCS electrical connector to the service part OCS electrical connector.
2. Install the 2 wiring clips on the wiring harness to the cushion pan.
3. If equipped with heated seats, connect the heated seat module electrical connector, install the wiring clip on the wiring harness to the cushion
pan, and connect the 2 cushion heater mat electrical connectors.
4. Tie-strap the unused seat wire harness pressure sensor electrical connector safely aside.
5. Tie-strap all loose wire harnesses and electrical connectors safely aside.
8. Install the front passenger seat and repower the SRS. For additional information, refer to Seats. Do not prove out the SRS within the seat
installation procedure. Proceed to the next step after seat installation and repowering the SRS to carry out the system reset procedure.
9. 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.
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 OCS system reset.
10. 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
11. 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.
12. Prove out the SRS as follows:
Turn the ignition from ON to OFF. Wait 10 seconds, then turn the ignition back ON and 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 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 RCM and OCSM DTCs using a scan tool.
