M-ASTC DTC Set Conditions

The M-ASTC-ECU constantly monitors the solenoid valve drive circuits. These codes are output if the M-ASTC-ECU judges that there is an open circuit or short-circuit in a solenoid coil or harness because the solenoid valve is on but no current flows to the solenoid valve, or if current continues flowing to the solenoid valve even though the solenoid valve is off.
