FREEZE FRAME DATA
- FREEZE FRAME DATA NOTE: Freeze frame data values will vary depending on the measurement conditions, surroundings, or vehicle conditions. For this reason, there may be a problem even when the values are within specifications. Turn the engine switch on (IG) and park the vehicle on level ground. Check the freeze frame data by using the Techstream. Turn the engine switch off. Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on.

FAIL-SAFE CHART
HINT
If the power source voltage to the multiplex tilt and telescopic ECU returns to normal within 10 seconds during tilt or telescopic operation, the operation will be resumed. If it returns to normal after 10 seconds have elapsed, the operation restarts when a tilt or telescopic operation signal is again input to the multiplex tilt and telescopic ECU.
| DTC Code | Detection Item | Fail-safe Operation |
|---|---|---|
| B2603 | Tilt and Telescopic Switch Circuit Malfunction | The tilt and telescopic operation using the switch is suspended. |
| B2610 | Tilt Position Sensor or Tilt Motor Circuit Malfunction | The tilt operation is suspended. |
| B2611 | Telescopic Position Sensor or Telescopic Motor Circuit Malfunction | The telescopic operation is suspended. |
| B2620 | ECU Power Source Circuit Malfunction | The tilt and telescopic operation is suspended. |
| B2621 | Communication Interruption | The tilt and telescopic operation is limited depending on which ECU has lost communication. For details, refer to Fail-safe Function. |
| B2624 | Speed Signal Malfunction | The auto away/return function stops. |
FAIL-SAFE OPERATION
- FAIL-SAFE FUNCTION If a malfunction in the tilt position sensor signal or telescopic position sensor signal occurs while operating the power tilt or power telescopic function, the multiplex tilt and telescopic ECU stops the operation of the power tilt and power telescopic steering column system. If the power source voltage to the ECU drops below approximately 8 V while operating the power tilt or power telescopic function, the ECU stops the operation of the power tilt and power telescopic steering column system. If the ECU detects that the motor has locked during the operation of the power tilt or power telescopic function, the ECU stops the operation of the power tilt and power telescopic steering column system. If the communication of an ECU that is related to the power tilt and power telescopic steering column system is interrupted, the control of functions by the multiplex tilt and telescopic ECU is limited as shown in the table below.
