Refer to DTC Diagnosis Procedure.
NO>>
To check malfunction symptom before repair: Refer to Intermittent Incident.
NO>>
Confirmation after repair: Inspection End
DTC Diagnosis Procedure
CHECK SELF-DIAGNOSIS RESULTS
CONSULT
Check if any DTC is detected in “Self Diagnostic Result” of “LASER/RADAR”.
Is any DTC detected?
YES>>
Perform diagnosis on the detected DTC and repair or replace the malfunctioning parts. Refer to DTC Index.
NO>>
Replace the ADAS control unit. Refer to Removal and Installation.

DTC Description
DESCRIPTIONECM receives vehicle speed signals from two different paths via CAN communication line: One is from the ABS actuator and electric unit (control unit) via the combination unit and the other is from TCM.DTC DETECTION LOGICAt 20 km/h (13 MPH), ECM detects the following status continuously for 5 seconds or more: The difference between a Nissan Murano vehicle speed calculated by a output speed sensor transmitted from TCM to ECM via CAN communication and the Nissan Murano vehicle speed indicated on the combination meter exceeds 15km/h (10 MPH)...
