Nissan Juke Service and Repair Manual : On Board Diagnosis (OBD) System of CVT and Engine
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the driver of a malfunction causing emission deterioration.
CAUTION:
• Be sure to turn the ignition switch OFF and disconnect the battery cable from
the negative terminal
before any repair or inspection work. The open/short circuit of related
switches, sensors, solenoid
valves, etc. will cause the MIL to light up.
• Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease, dirt, bent terminals, etc.) • Be sure to route and secure the harnesses properly after work. Interference of the harness with a bracket, etc. may cause the MIL to light up due to a short circuit.
• Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube may cause the MIL to light up due to a malfunction of the EGR system or fuel injection system, etc.
• Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and ECM before returning the vehicle to the customer.
General Precautions
• Turn ignition switch OFF and disconnect the battery cable
from the negative terminal before connecting or disconnecting
the CVT assembly harness connector. Because battery
voltage is applied to T ...
