ABS (Antilock Brake System)

DTC 58 HV SYSTEM REGENERATIVE MALFUNCTION

CIRCUIT DESCRIPTION

DTC Detecting Condition:

The skid control ECU communicates with the hybrid control ECU and controls braking force according to the motor's regenerative force.
The skid control ECU sends Enhanced VSC signal to the hybrid control ECU and inputs operating signal from the hybrid control ECU.

The skid control ECU uses CAN communication for communication with the hybrid control ECU. If a communication malfunction is memorized, the skid control ECU prohibits Enhanced VSC operation and a part of ECB control by fail safe function.

C1259/59 is stored if the power switch ON (READY) with the HV battery service plug disconnected.

HINT: This DTC is output from the skid control ECU when the hybrid control ECU sends a malfunction signal to the skid control ECU.
