DESCRIPTION
The skid control ECU (master cylinder solenoid) measures the speed of each wheel by receiving signals from the speed sensors. These signals are used for recognizing whether all 4 wheels are operating properly. Therefore, all wheel signals must be equal.

CAUTION / NOTICE / HINT
NOTICE:
Check the speed sensor signal after replacement (See page
).
PROCEDURE
1. |
CHECK TIRE SIZE |
(a) Check tire size and condition of all 4 wheels.
OK:
All 4 wheels are the same size and in the same condition.
NG | ![]() |
REPLACE TIRES SO THAT ALL 4 TIRES ARE SAME IN SIZE |
|
2. |
CHECK SPEED SENSOR ROTOR |
(a) Remove the drive shaft, and check around the speed sensor rotor.
OK:
No scratches or foreign matter on the sensor tip.
NG | ![]() |
REPLACE SPEED SENSOR ROTOR |
|
3. |
CHECK SPEED SENSOR |
(a) Check the speed sensor circuit.
NG | ![]() |
REPLACE SPEED SENSOR |
|
4. |
CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - EACH SPEED SENSOR) |
(a) Check the speed sensor circuit .
NG | ![]() |
REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
5. |
RECONFIRM DTC |
(a) Clear the DTCs (See page
).
(b) Drive the vehicle at more than 20 km/h (13 mph) for more than 60 seconds.
(c) Check if the same DTCs are detected.

Pressure Control Solenoid "C" Circuit Open (P079513)
DESCRIPTION
Changing from 1st to 6th is performed by the ECM turning shift solenoid valves
SL1, SL2, SL3 and SL4 on and off. If an open or short circuit occurs in any of the
shift solenoid valves, the ECM controls the remaining normal shift solenoid valves
to allow the vehicle to be operated ...

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 ...
