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 (spiral cable with sensor sub-assembly) zero point malfunction diagnostic function.

PROCEDURE
1. |
CHECK DTC |
(a) Clear the DTCs (See page
).
(b) Turn the ignition switch off.
(c) Turn the ignition switch to ON again and check that no CAN communication
system DTC is output (See page
).
(d) Start the engine.
(e) Drive the vehicle at a speed of 35 km/h (22 mph) and turn the steering wheel
to the right and left, and then check that no speed sensor or yaw rate and acceleration
sensor (airbag sensor assembly) DTCs are output (See page
).

Pressure Control Solenoid "A" Actuator Stuck Off (P07457F)
SYSTEM DESCRIPTION
The ECM uses the vehicle speed signal and signals from the transmission revolution
sensors (NT, SP2) to detect the actual gear (1st, 2nd, 3rd, 4th, 5th or 6th gear).
The ECM compares the actual gear with the shift schedule in the ECM memory to
detect mechanical problems of t ...
Compressor Lock Sensor Circuit (B1422/22)
SYSTEM DESCRIPTION
The ECM sends the engine speed signal to the air conditioning amplifier assembly
via CAN communication.
The air conditioning amplifier assembly reads the difference between compressor
speed and engine speed. When the difference becomes too large, the air conditioning
ampli ...
