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.

ConditionPossible cause Correction / Reference Item
Whistling sound is heard
from A/C evaporator Depending on the combination of the
interior / exterior temperatures, engine
rpm and refrigerant pressure, the
refrigerant flowing out of the expansion
valve may, under certain conditions,
make a whistling sound At times, slightly decrea
sing refrigerant volume
may stop this noise.
Inspect expansion valve and replace if faulty.

chirping sound in
proportion to its speed of
rotation Worn or damaged motor brushes or
commutator
Replace blower motor.
Fluttering noise or large
droning noise is heard
