PID/DATA monitor inspection
- Park the vehicle on level ground.
- Verify the ambient temperature.
Ambient temperature is below freezing
- After warming up the engine for approx.1 hour, go to the next step.

- After warming up the engine for approx.1 hour, go to the next step.
- Connect the M-MDS to the DLC-2.
- Switch the ignition ON (engine off).
- Using the M-MDS, display the DEF temperature (PID: S_UR_TANK_TMP) detected by the urea temperature sensor and the DEF temperature detected by the quality sensor (PID: DEF_T) (See ON-BOARD DIAGNOSTIC TEST .) (See ON-BOARD DIAGNOSTIC TEST [DOSING CONTROL UNIT (SKYACTIV-D 2.2)] .)
- Verify that the difference in values between PID S_UR_TANK_TMP and PID DEF_T is within ±6°C.
- If the output value is out of the range, replace the quality sensor. (See DEF QUALITY SENSOR REMOVAL/INSTALLATION .)
