        Tech Tips


        • for Segment Display Type:


          • If the 4WD/AWD warning light does not blink, perform relevant troubleshooting procedures. The relevant troubleshooting procedures are in the sections listed in the table below.

          • When the system is operating correctly, each light will blink continuously in a pattern of 0.25 seconds on, then 0.25 seconds off.

          • When one DTC is output, each light will output the same code at 4-second intervals. (For example, Code 21 would be output as 2 flashes, a 1.5-second pause, and then 1 flash).

          • When 2 or more DTCs are output, each light will output a different code at 2.5-second intervals, and when all codes have been output, there will be a 4-second pause and the sequence will repeat.

          • When multiple codes are set, they are output in order starting with the lowest DTC number.

        • for Dot Display Type:


          • If no DTCs are displayed on the multi-information display, perform the relevant troubleshooting procedures. The relevant troubleshooting procedures are in the sections listed in the table below.

          • "4WD" is displayed on the multi-information display, and the 4WD ECU assembly checks the system for malfunctions.

          • If the dynamic torque control 4WD/AWD system is normal, "4WD FF" will be displayed on the multi-information display (normal system code).

          • If the dynamic torque control 4WD/AWD system is not normal, "4WD XX (DTC)" will be displayed on the multi-information display.

        • DTCs are explained in "DIAGNOSTIC TROUBLE CODE CHART".
