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.
