Vehicle Control History
| FFD Group | Code | GTS Display | Detection Condition | Vehicle Behavior | Suspected Cause |
|---|---|---|---|---|---|
| 01 | X3200 | EV Output Limit | 1. Power limitation was applied due to overheat of the EV system |
|
Continuously high load operation Tech Tips If the temperature becomes high, the power may be temporarily limited until the temperature returns to normal. |
| 2. Power limitation for a low FC coolant temperature was applied |
|
Low ambient temperature Tech Tips In cold climate areas, the power output may be temporarily limited even if the READY indicator has come on. Once the FC system has warmed up, the limitation will be removed. |
|||
| 3. Power limitation for a high FC coolant temperature was applied |

| 02 | X3210 | Br Mode Reject | Shift lever was put into Br mode despite Br mode being unavailable to use (*1) |
|
*1: If any one of the following conditions is applicable, Br mode will become unavailable to use.
If Br mode is not available to use, deceleration force of the regenerative brake may be reduced. In such a situation, use the brake pedal to decelerate the vehicle. |
| 03 | X3220 | FC Stack Shock History | Signal, which indicates that G force greater than the threshold value was applied, was received from the airbag ECU | - | Road surface interference / collision |
| 04 | X3240 | Fuel Lid Interlock Activate | Freeze Frame data will be stored when any of the following conditions are met.
Refer to each type of Freeze Frame Data.
|
Power switch cannot be turned on (READY), multi-information display shows "Close H2 Filler Door and Restart Your Vehicle" |
|
| When power switch is on (READY) (*3), hydrogen filling is performed and power switch is forced to turn off, and the multi-information display shows "H2 Filler Door is open. Park Your Vehicle in a Safe Place and Close H2 Filler Door". |
|
||||
| 05 | X0450 | Battery Smart Unit Mismatch | Different types of battery voltage sensors are mounted | READY ON cannot be activated | Incorrect battery voltage sensor has been installed. |
*2: If Br mode frequently becomes unavailable to use due to highly SOC of the EV battery, it is presumed that the electric heater is malfunctioning. If the electric heater malfunctions, regenerative energy cannot be handled properly, causing the EV battery SOC to increase.
*3: When the fuel lid is actually open, but due to a malfunction in the fuel lid interlock switch, etc., the hydrogen fuel control ECU detects the fuel lid as being closed, and the power switch has been allowed to turn on (READY).
