DTC C1063: Solenoid Valve Power Supply Driver CircuitS7RS0B4504016
Wiring Diagram
DTC Detecting Condition
ABS control module monitors the voltage at the terminal of solenoid circuit constantly with ignition switch turned ON.
Also, immediately after ignition switch is turned ON, perform initial check as follows.
Switch solenoid valve power supply driv er (transistor) in the order of OFF → ON and check if voltage changes to Low
→ High. If anything faulty is found in the initial check and when the voltage is low with ignition switch turned ON, this
DTC will be set.
