WARNING: This page is about a different car, the 2008 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
If using CONSULT-III, refer to
"SELF-DIAGNOSIS ".
The self-diagnostic system diagnoses sensors, CAN system, battery voltage, and stuck button on front air control. Refer to applicable service information (items) for details. Shifting from usual control to the self-diagnostic system is accomplished by the following:
The ignition switch must be on and ambient temperature must be at least 10°C (50°F). Press the A/C switch to turn on the HVAC system. Press the vent and defrost button at the same time. Then press the recirculation switch. The fault codes (if any are present) will display in the ambient temperature area. Refer to "SELF-DIAGNOSIS CODE CHART ". The fault codes will continue to scroll until self-diagnostic mode is exited. To exit self-diagnostic mode, press any button.
