OCS1P_w142_tempHumidityInvalid
What does OCS1P_w142 mean?
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).

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.
