OK -- Continue to next step.
3. RECONFIRM DTC
(a) Turn the engine switch off.
(b) Clear the DTCs See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Reading and
Clearing Diagnostic Trouble Codes.
(c) Start the engine.
(d) Drive the vehicle and turn the steering wheel to the right and left at the speed of 35 km/h (22 mph) or more.
(e) Check if the same DTC is recorded See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and
Inspection/Reading and Clearing Diagnostic Trouble Codes.
Result:
HINT
- If the same DTC C1439 and/or C1445 is not output again, the DTC may have been stored due to a temporary loss of the
steering angle zero point calibration, such as when the power source voltage drops.
- If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next
step See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Symptom Related
Diagnostic Procedures/Problem Symptoms Table.

BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: C1439,C1445: Steering Angle
Sensor Initialization Incomplete
DESCRIPTION
The skid control ECU acquires the steering angle sensor zero point every time the engine switch is turned on (IG) and the vehicle is driven at 35
km/h (22 mph) or more for approximately 5 seconds. The ECU also stores previous zero points.
DTCs C1439 and C1445 will be cleared when the engine switch is turned off.
INSPECTION PROCEDURE
NOTICE:
Before proceeding with the inspection, explain to the customer that the output DTC is related to temporary loss of the steering
angle zero point calibration, such as when the power source voltage drops when the battery is removed, and confirm that this
