Note
•  The remaining distance to empty is a maximum of 700 km {435 mile} until the malfunction targeted by inducement (laws and regulations requirement) is repaired. This distance is displayed in the instrument cluster and counts down until the targeted malfunction is repaired.
•  Perform the following restrictions while driving the vehicle according to the remaining distance to empty.
―  700 to 650 km {435 to 404 miles}: No restriction
―  650 to 0 km {404 to 0 miles}: Maximum vehicle speed is restricted from 80 to 50 km/h{50 to 31 mph}
―  0 km {0 miles}: Engine speed is fixed at idle speed
POSSIBLE CAUSE
•  Malfunction in SCR system detected by dosing control unit or PCM
•  Dosing control unit malfunction
•  PCM malfunction

VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the following using the M-MDS simulation function.
―  Build-up
―  Turn ON the urea hose heater (Simulation item: HTR_LINE)
―  Turn ON the urea tank heater (Simulation item: THR_TANK)
•  Perform compulsory diesel particulate filter regeneration.
•  Verify that there is no warning message indicating that there is a low level of AdBlue® in the multi-information display.
Note
•  Switch the ignition from ON (engine off) to OFF and then switch it ON (engine off) again to cancel the vehicle speed restriction.
•  Switch the ignition off.
•  Switch the ignition ON (engine off).
•  Verify the instrument cluster display content.
•  Are SCR system related warnings displayed in the instrument cluster?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
