Vehicle Condition and Fail-safe Function when Malfunction Detected
DTC Code Vehicle Condition when Malfunction Detected Fail-safe Function when Malfunction Detected
U0100 There is no effect on vehicle behavior.

If the following conditions are met, it is determined that the malfunction is not in the direct line (NE) but in CAN communication.


  • When the engine switch is pressed, the system controls the engine based on the engine speed signal via direct line, causing the engine to stop cranking.

  • When the engine switch is pressed and held, the system controls the engine based on the engine speed signal via direct line, causing the engine to stop cranking.

If the following conditions are met, it is determined that there is a malfunction in both CAN communication and the direct line (NE).


  • When the engine switch is pressed, the engine stops cranking after 6 seconds.

  • When the engine switch is pressed and held, the engine remains cranking for up to 30 seconds.
U0103 The shift state does not change from park (P) to shift state other than park (P). -
U0129 Engine does not start. -
U0140 The warning (meter buzzer) does not sound and no warning messages displayed on the multi-information display. -
U0142

  • Doors cannot be locked or unlocked.

  • The warning (wireless buzzer) does not sound (w/ Door Ajar Warning Function).

 -
U0155

  • The warning (meter buzzer) does not sound and the meter does not indicate a warning.

  • There is no effect on vehicle behavior.

 -
U0199 Driver side door entry lock and unlock operation does not operate. -
U0200 Front passenger side door entry lock and unlock operation does not operate. -
U0230 Power trunk lid does not operate. -
U1103

  • The engine stall misjudgment is done by the idling stop by stop and start system.

  • Immobiliser set is done by the door operation in the idling stop by stop and start system

 -
U1117 The engine cannot be started using the wireless remote control function. -

CAUTION / NOTICE / HINT

Note


  • When using the GTS with the engine switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start. While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.

  • After repair, confirm that no DTCs are output by performing "DTC Output Confirmation Operation".

Tech Tips

When the cable is disconnected and reconnected to the negative (-) battery terminal, the power source mode returns to the state it was in before the cable was disconnected.

PROCEDURE


  1. CHECK FOR DTC


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / Entry&Start, Power Source Control / Trouble Codes.

    5. Check for DTCs and note any DTCs that are output.
