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 <15.5V for 10 seconds or more.

This error is detected by the ECU. Sensor short to GND or short to plus or broken sensor line and all LIN errors

Five consequitive internal errors occured.

As soon as error condition is no longer present (no power cycle required)

This error is detected by the ECU. Sensor dirt can be detected through any or all of these methods 1. high attenuation time 2. constant echos when vehicle is in motion . 3. low attenuation time 4. jittering attenuation time.

Five consequitive samples of blockage condition being set.

Blockage condition is no longer present (no power cycle required)

Undervoltage detected by the ECU

Sets when the ECU supply voltage is < 9V for 10 seconds or more.

Resets when the ECU supply voltage is >9.5V for 10 seconds or more.
