Tesla warning code in the Occupant Classification System (OCS1P) module. The temperature or humidity measurement is invalid Communication with the temp/humidity sensor has been lost Communication with temp/humidity sensor is restored The sandwich sensor is not calibrated The seatback self capacitance sensor is low The passenger airbag installed is not allowed with an OCS with no sandwich The OCS determines that an incorrect airbag is installed The passenger airbag is replaced to match the expectation of OCS The cushion self capacitance sensor is shorted to ground Adjacent sensor noise detected. Set when the sensor internal temperature is over 150deg C. Cleared when sensor internal temperature is below the hysteresis level 10degc below set point Sensor function will be impaired, park assist features will be disabled. Invalid communication from SCCM At least 3 consequitive invalid messages (of same message type). Clears automatically when messages are received Some park assist functionality not availble Overvoltage detected by the ECU Sets when the ECU supply voltage is > 16V for 10 seconds or more. Resets when when the ECU supply voltage is 9.5V for 10 seconds or more. Failed to read or write NVRAM. Failure to read or write NVRAM. Clears on next normal boot cycle where read is succesful Default calibration parameters are used. Invalid communication from EPB Invalid communication from EPAS Expected messages from DAS/APP missing. Messages missing for more than 3 nominal cycle times. Sensor internal failure occured - like sensor damping resistor error or broken or disconnected membrane error, self diagnosis error or sensor reset or sensor resonator drift Expected messages from RCM missing. Sensor supply voltage outside of specificaiton Park assist functionality unavailable. Expected messages from DI missing. Expected messages from ESP missing. ECU recovered from a SW watchdog reset. ECU was previously reset due to watchdog event. Clears on next normal boot cycle The secondary controller area network (CAN) bus is in the busoff state.
