Judgement Self-diagnosis
WARNING: This page is about a different car, the 2005 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.
When a malfunction is detected, the malfunction route is indicated by flickering of the 4WD warning lamp.
CAUTION:
- If "CAN communication" is displayed with other DTCs, first perform the trouble diagnosis for CAN communication line.
- If "ABS operation signal", "VDC operation signal" or "TCS operation signal" is displayed, first perform the trouble diagnosis for ABS system.
- If "Output shaft revolution signal" is displayed, first perform the trouble diagnosis for A/T system.
NOTE:
- If "actuator position switch" or "actuator circuit" is displayed, first erase self-diagnostic results. ("Actuator position switch" or "actuator circuit" may be displayed after installing transfer control unit or transfer assembly.)
- If "clutch pressure switch" or "line pressure switch" is displayed only while driving in reverse, check the continuity of "R" position on A/T PNP switch. When there is nothing wrong with the electrical system, check the hydraulic system.
