DTC 597 TRANSMISSION CONTROL ECU MALFUNCTION

CIRCUIT DESCRIPTION


Circuit Description:




DTC Detection Condition:




When a signal is input from the P position switch or selector lever, the HV control ECU transmits a P position control (PCON) signal to the transmission control ECU. Based on this signal, the transmission control ECU actuates the shift control actuator in order to mechanically lock or unlock the counter drive gear in the HV transaxle assembly. If the shift control actuator is in the P position, the transmission control ECU transmits a P position (PPOS) signal to the HV control ECU.
