Steering Angle Sensor Power Source Voltage Malfunction (C1432)
DESCRIPTION
Steering angle sensor (spiral cable with sensor sub-assembly) signals are sent
to the skid control ECU (master cylinder solenoid) via the CAN communication system.
When there is a malfunction in the CAN communication system, it is detected by the
steering angle sensor zero point m ...

CHECK FREEZE FRAME DATA
HINT:
The ECU records vehicle and driving condition information as freeze frame data
the moment a DTC is stored.
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: P ...
