DESCRIPTION
The yaw rate sensor and deceleration sensor signal is sent to the skid control ECU through the CAN communication system. When there is a malfunction in the communication, it will be detected by the diagnosis function.

INSPECTION PROCEDURE
HINT: When U0073/94, U0100/65, U0123/62, U0124/95 or U0126/63 are output accompanied with C1232/32, C1234/34, C1243/43, C1244/44, C1245/45 or C1381/97, inspect and repair the trouble areas indicated by U0073/94, U0100/65, U0123/62, U0124/95 or U0126/63 first.
1 CHECK YAW RATE AND DECELERATION SENSOR INSTALLATION
(a) Check that the yaw rate and deceleration sensor has been installed properly (See page BC-197).
OK: The sensor should be tightened to the specified torque.
The sensor should not be tilted.
2 INSPECT YAW RATE AND DECELERATION SENSOR (IG TERMINAL)
(a) Disconnect the yaw rate and deceleration sensor connector.
(b) Turn the ignition switch to the ON position.
(c) Measure the voltage according to the value(s) in the table below.
Standard voltage
3 INSPECT YAW RATE AND DECELERATION SENSOR (GND TERMINAL)
(a) Disconnect the yaw rate and deceleration sensor connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance

Speaker Circuit
DESCRIPTION
The sound signal that has been amplified by the stereo component amplifier is
sent to the speakers from
the stereo component amplifier through this circuit.
If there is a short in this circuit, the stereo component amplifier detects it
and stops output to the speakers.
Thus s ...
Diagnosis system
1. CHECK DLC3
The vehicle's ECU uses ISO 15765-4 for
communication protocol. The terminal arrangement
of the DLC3 complies with SAE J1962 and matches
the ISO 15765-4 format.
NOTICE:
*: Before measuring the resistance, leave the
vehicle as is for at least 1 minute and do ...
