Occupant Classification Sensor Control Module (OCSCM)
The OCSCM translates the load readings into a seat occupancy status and transmits the result to the RCM, on the HS CAN powertrain systems bus. The OCSCM incorporates two load limits for the seat cushion: When the load is less than the lower limit, the seat is classified as unoccupied; when the load exceeds the lower limit, but is less than the upper limit, the seat is classified as occupied by a child; when the upper limit is exceeded, the seat is classified as occupied by an adult.
The following pre-conditions are required to run the routine correctly:
- Ignition is switched on
- No collision event received from the RCM during the current ignition cycle
- No faults present in the current ignition cycle
- The passenger seat is bolted in its original installation position
- The OCSCM has gone through the seat assembly plant calibration
- The OCSCM has settled for 10 seconds
- Temperature is between 6°C (42°F) and 36°C (97°F).
- If the passenger seat connector has been disconnected during a repair procedure, can cause a "Missing calibration" DTC. Run the "Learn seat occupant classification zero position" routine to reset the OCSCM using Jaguar approved diagnostic equipment.
- If the passenger seat is not in the installed position when the ignition is switched on, can cause a "Missing calibration" DTC. Run the "Learn seat occupant classification zero position" routine to reset the OCSCM using Jaguar approved diagnostic equipment.
The following pre-conditions are required to run the routine correctly:
- The passenger seat is empty when the ignition is switched on
- The passenger seatbelt is not buckled
- The engine is running
- Wait 10 seconds to ensure that no pressure fluctuations occur.
Clear DTCs and retest the system after the "Learn seat occupant classification zero position" routine has been carried out. If the routine fails for any reason, request the routine results using the Jaguar approved diagnostic equipment.
