FLASH CODE CHART

Flashing pattern Item Diagnostic item is detected when... Reference
2 Output shaft revolution signal (from TCM)
  • Malfunction is detected in output shaft revolution signal that is output from TCM through CAN communication.
  • Improper signal is input while driving.
 
3 Vehicle speed signal (from ABS)
  • Malfunction is detected in vehicle speed signal that is output from ABS actuator and electric unit (control unit) through CAN communication.
  • Improper signal is input while driving.
 
4 CAN communication Malfunction has been detected from CAN communication.  
5 AD converter AD converter system of transfer control unit is malfunctioning.  
6 4LO switch Improper signal from 4LO switch is input due to open or short circuit.  
7 Engine speed signal
  • Malfunction is detected in engine speed signal that is output from ECM through CAN communication.
  • Improper signal is input while driving.
 
8 Power supply Power supply voltage for transfer control unit is abnormally low while driving.  
9 4WD shift switch More than two switch inputs are simultaneously detected due to short circuit of 4WD shift switch.  
10 Wait detection switch Improper signal from wait detection switch is input due to open or short circuit.  
11 Actuator motor
  • Motor does not operate properly due to open or short circuit in actuator motor.
  • Malfunction is detected in the actuator motor. (When 4WD shift switch is operated and actuator motor is not operated.)
  • Malfunction is detected in transfer shift high relay or transfer shift low relay.
 
12 Actuator position switch

  • Malfunction is detected in the actuator position switch.
 
13 Transfer control device
  • Malfunction is detected in transfer shut off relay 1 and transfer shut off 2.
  • Malfunction occurs in transfer control device drive circuit.
 
14 PNP switch signal When PNP switch signal is malfunctioning. (A/T models), (M/T models)
Repeats flickering every 0.25 sec. Data erase display
  • Power supply failure of memory back-up.
  • Battery is disconnected for a long time.
  • Battery performance is poor.
 
Repeats flickering every 2 to 5 sec. - Circuits that the self-diagnosis covers have no malfunction. -
No flickering PNP switch or 4WD shift switch PNP switch or 4WD shift switch circuit is shorted or open. or
NOTE: If actuator position switch" or transfer control device" is displayed, first erase DTC. (They may be displayed after installing transfer control unit or transfer assembly.)
