Seat System - Seating: Other Ford Fiesta Mk6

Front Seats

The front seats are equipped with the following serviceable systems

1. 2-way seat track (passenger only)
2. 4-way seat track (driver only)
3. Manual recliners (serviced with backrest frame)
4. Heated seats (if equipped)
5. Occupant Classification Sensor (OCS) (passenger seat only, if equipped)
6. Seat side air bags (in seat backrests) (if equipped)
7. Safety belt buckles
8. Seat track position sensors (if equipped)

Seat Backrests

The recliner mechanism is part of the seat backrest frame and is not serviced separately.

Seat Tracks

Front seats are equipped with a 2-way manual passenger seat track and 4-way manual driver seat track which includes a height adjust handle that ratchets to raise and lower the seat. Both seat tracks are serviced as complete assemblies which include the cushion frames and seat mounting feet.

Heated Seats

The heated seat system includes the following serviceable components

1. Cushion heater mats (attached to seat cushion foam pads)
2. Heated seat relays (located in the Central Junction Box (CJB))
3. Heated seat switches (located on the instrument panel)
4. Thermostats (serviced only as part of each cushion heater mat)
5. Body Control Module (BCM)

Note. If a new heater mat is needed on a front passenger seat cushion equipped with an Occupant Classification Sensor (OCS) system, install a new OCS service kit with a heater mat already adhered to the cushion foam pad.

The cushion heater mats are serviceable separately. A heater mat can be peeled away from a foam pad and a new one adhered in its place providing excessive foam is not removed from the foam pad. If excessive foam is removed during removal, a new foam pad must be installed. A heater mat cannot be reused; the 2-way tape adhesive will no longer hold the heater mat position on the foam pad causing it to shift or bunch up.

Occupant Classification Sensor (OCS) System

Note. OCS system components, seat wiring harness, seat cushion foam pad, bladder with pressure sensor and Occupant Classification System Module (OCSM) are calibrated to each other and are serviced as an assembly. If new OCS system components are needed, an OCS system service kit must be installed as an assembly.

For information on diagnosing or servicing the OCS system, refer to SUPPLEMENTAL RESTRAINT SYSTEM .

Seat Side Air Bags

Driver and passenger seat side air bags are attached to the seat backrest frame. For diagnostic information, or if the seat side air bag has deployed, refer to SUPPLEMENTAL RESTRAINT SYSTEM .

Rear Seats

The rear seat cushion and 60/40 fold flat backrests are equipped with the following serviceable components

1. Backrest and cushion trim covers and foam pads
2. Backrest hinges (attached to floor pan)
3. Backrest latches (attached to backrest frame)
4. Backrest latch strikers (attached to quarter panel)
5. Cushion latches (located underneath cushion front edge attached to floor pan)
6. Head restraints and head restraint guides (attached to the backrests)

The heated seat system only operates when the engine is running. When the heated seat switch(es) (located on the instrument panel) is activated, it supplies a ground signal to the Body Control Module (BCM). When the BCM receives the heated seat switch signal, it activates the appropriate (driver or passenger) heated seat relay, (located in the Central Junction Box (CJB). When the heated seat relay is activated, voltage is supplied to the cushion heater mat. The cushion heater mats are directly connected to ground to complete the electrical circuit to heat the seat.

Each cushion heater mat contains a non-serviceable internal thermostatic switch that closes when cold to complete the heater grid circuit and heat the seat. When hot, the thermostatic switch opens the heater grid circuit and allows the seat to cool. During normal operation, several minutes may be required before seat temperature is increased and several more minutes of cooling before the heater mats continue with heating. The heated seat indicator illuminates continuously while the thermostatic switch cycles between open and closed.

The seat should be occupied to correctly test for normal operation. Temperature measuring devices do not provide an accurate method for testing heated seat operation as surface temperatures are subject to human and environmental characteristics. Correct testing requires heater mat resistance measurements which have tight tolerances affecting heat cycle time length.

The heated seat system does not time-out. A heated seat remains on until it is turned off by the heated seat switch or the ignition is switched OFF.

Pinpoint Tests

Note. Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

Refer to INSPECTION AND VERIFICATION and the SYMPTOM CHART for direction to the appropriate Pinpoint Test.

1. 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. NOTE: To prevent system failure, take the following precautions before carrying out the Occupant Classification Sensor (OCS) system reset: Make sure the voltage to the Occupant Classification System Module (OCSM) is greater than 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 between 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 and during the OCS system reset process. Prior to carrying out the OCS system reset, make sure a minimum of 8 seconds has elapsed after cycling the ignition switch ON. Carry out the OCS system reset.
2. 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
3. NOTE: Cycle the ignition switch 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 «SUPPLEMENTAL RESTRAINT SYSTEM»(ref-382402) .
4. 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 illuminate 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 may not illuminate 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 sounds in a pattern of 5 sets of 5 beeps. If this occurs, diagnose and repair the air bag warning indicator and any SRS fault discovered. Use a scan tool and clear all continuous DTCs from the RCM and Occupant Classification System Module (OCSM).
