| DTC Code | DTC Name |
|---|---|
| P057113 | Brake Switch "A" Circuit Open |
DESCRIPTION
When the brakes are applied by the dynamic radar cruise control system, the skid control ECU assembly operates the No. 3 semiconductor power integration ECU to illuminate the stop lights.
If the hybrid vehicle control ECU assembly receives a No. 3 semiconductor power integration ECU malfunction signal from the skid control ECU assembly, DTC P057113 is stored.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| P057113 | Brake Switch "A" Circuit Open | While the vehicle speed is 5 km/h (3 mph) or more and the dynamic radar cruise control system is operating, the hybrid vehicle control ECU assembly receives a No. 3 semiconductor power integration ECU malfunction signal from the skid control ECU assembly for approximately 0.2 seconds or more. |

CAUTION / NOTICE / HINT
Note
If the main body ECU (multiplex network body ECU) is replaced, refer to the Service Bulletin.
The vehicle is equipped with a sub-battery. Therefore, ensure there is no power being supplied to the vehicle when disconnecting or reconnecting the connector of the shift control ECU and when removing or installing the shift control ECU.
PROCEDURE
CHECK FOR DTCs (POWER INTEGRATION SYSTEM)
Check for DTCs.
Tech Tips
If there is a malfunction in the No. 3 semiconductor integration ECU, integration relay system DTCs may also have been detected. Check the integration relay system first.
