Occupant Classification Sensor Control Module (OCSCM) New Module Replacement And Programming

NOTE: Do not attempt to install individual components from the Occupant Classification Sensor (OCS) service kit, as they are calibrated to function as a single assembly. The complete service kit consists of foam, occupant classification sensor bladder mat with attached smart digital pressure sensor. They MUST NOT be installed separately. To ensure the correct function, it is essential both parts are installed together, as it is a safety critical system.
  1. Remove the passenger seat from the vehicle. Refer to: FRONT ROW SEAT - INGENIUM I4 2.0L DIESEL/INGENIUM I4 2.0L DIESEL AJ21/INGENIUM I4 2.0L PETROL/INGENIUM I4 2.0L PETROL - PHEV/TDV6 3.0L DIESEL/V6 S/C 3.0L PETROL
  2. Install a new OCS service kit to the seat.Refer to: OCCUPANT CLASSIFICATION SENSOR (G1918064) 
  3. Re-install the seat and ensure all electrical connectors are secure. Ensure the seat is correctly mounted and fixings are tightened to the correct torque. Refer to: FRONT ROW SEAT - INGENIUM I4 2.0L DIESEL/INGENIUM I4 2.0L DIESEL AJ21/INGENIUM I4 2.0L PETROL/INGENIUM I4 2.0L PETROL - PHEV/TDV6 3.0L DIESEL/V6 S/C 3.0L PETROL
    NOTE: Ensure the vehicle is stationary and on a level surface. The seat must be secure and in an upright position before performing the next step. Failure to do this could induce a DTC.
  4. Connect the Jaguar Land Rover approved diagnostic equipment, set the ignition to ON and wait 5 seconds for the module to wake up
  5. Using the Jaguar Land Rover approved diagnostic equipment, refer to datalogger signals ECU calibration Data #1 Number (0xF124), ECU Delivery Assembly Number (0xF113), ECU Core Assembly Number (0xF111), ECU Strategy Number (0xF188). Make a note of the OCS control module part number to ensure it is the correct part number for the vehicle
  6. Using the Jaguar Land Rover approved diagnostic equipment, check and update the OCS control module to the latest level software. Ensure the ignition is set to OFF and wait at least 7 seconds
  7. Set the OCS control module in to security access mode, after going in to an extended diagnostic session. Using the Jaguar Land Rover approved diagnostic equipment, check for any OCS control module or Restraints Control Module (RCM) related DTCs. If any DTCs are found, perform a software update
    NOTE: All OCS DTCs will be logged in the RCM.
  8. Set the ignition to OFF and wait 10 seconds
  9. Set ignition to ON and wait 10 seconds
  10. Set the OCS control module in to security access mode, after going in to an extended diagnostic session
  11. Using the Jaguar Land Rover approved diagnostic equipment, perform routine - Learn Seat Occupant Classification Zero Position (0x5007) This will re-calibrate the new OCS control module
  12. Set the ignition to OFF and wait at least 10 seconds
  13. Set the ignition to ON and wait 10 seconds. Ensure the SRS warning light is illuminated during the ignition test cycle. The SRS warning light should then extinguish after the 10 seconds to confirm no SRS faults exist
  14. If the Learn Seat Occupant Classification Zero Position (0x5007) routine passes (09) and no SRS warning light is illuminated, no further action is necessary. If the Learn Seat Occupant Classification Zero Position (0x5007) routine fails and/or the SRS warning light is illuminated, note which process of the routine failed and proceed to step 15
    1. 02 - Process Failed - Seat Not Calibrated. The Learn Zero position cannot be calibrated if the seat has not been correctly calibrated at the seat manufacturing plant. Install a new service kit as necessary and re perform Learn Seat Occupant Classification Zero Position routine (0x5007)
    2. 03 - Process Failed - Wait 10 Seconds To Re Zero. Wait 10 seconds after ignition ON and re perform Learn Seat Occupant Classification Zero Position routine (0x5007)
    3. 04 - Re Zero Failure - DTCs Set. A fault is preventing the Learn Seat Occupant Classification Zero Position routine (0x5007) from completing correctly. Check for DTCs and repair as necessary, then re perform Learn Seat Occupant Classification Zero Position routine (0x5007)
    4. 06 - Process Failed - OCS Pressure Out Of Range. The seat must be empty to perform the Learn Seat Occupant Classification Zero Position routine (0x5007) correctly. Ensure the seat is empty and re perform Learn Seat Occupant Classification Zero Position routine (0x5007)
    5. 07 - Process Failed - OCS Pressure Fluctuation. Check to ensure the OCS hose is correctly routed and clipped in position, as this could prevent the Learn Seat Occupant Classification Zero Position routine (0x5007) from completing correctly. Any vibrations or variations within the passenger compartment, i.e. doors opening/closing will prevent the Learn Seat Occupant Classification Zero Position routine (0x5007) from completing correctly. Ensure the passenger compartment environment is stable and re perform Learn Seat Occupant Classification Zero Position routine (0x5007)
    6. 08 - Process Failed - Temperature Out Of Range. Ensure the workshop temperature is within normal acceptable working range and re perform Learn Seat Occupant Classification Zero Position routine (0x5007)
    7. 09 - Process Completed - Re Zero Success. Routine has passed, no further actions necessary
  15. Using the Jaguar Land Rover approved diagnostic equipment, check for any OCS control module or RCM related DTCs. If any DTCs are found, refer to the relevant article of the service information and perform the relevant repair actions as necessary. Re-perform this procedure to re-calibrate the OCS control module
