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
