Diagnostic Procedure with Diagnostic Trouble Code (DTC)
Step
7 CHECK HARNESS BETWEEN DRIVER'S
CONTROL CENTER DIFFERENTIAL CON-
TROL MODULE AND YAW RATE & LATER-
AL G SENSOR.
Measure the resistance between the driver's
control center differential control module con-
nector and chassis ground.
Connector & terminal
(B380) No. 1 — Chassis ground:
8 CHECK YAW RATE & LATERAL G SENSOR.
1) Remove the yaw rate & lateral G sensors
from vehicle.
2) Connect the connector to the yaw rate & lat-
eral G sensor.
3) Connect the driver's control center differen-
tial control module connector.
4) Turn the ignition switch to ON.
5) Measure the voltage between connector
terminals of the yaw rate & lateral G sensor
when the yaw rate & lateral G sensor is horizon-
tally positioned.
Connector & terminal
(B230) No. 5 (+) — No. 6 (–):
9 CHECK YAW RATE & LATERAL G SENSOR.
Measure the voltage between connector termi-
nals of the yaw rate & lateral G sensor when the
yaw rate & lateral G sensor is inclined 90° to the
right from its install position.
Connector & terminal
(B230) No. 5 (+) — No. 6 (–):
10 CHECK YAW RATE & LATERAL G SENSOR.
Measure the voltage between connector termi-
nals of the yaw rate & lateral G sensor when the
yaw rate & lateral G sensor is inclined 90° to the
left from its install position.
Connector & terminal
(B230) No. 5 (+) — No. 6 (–):
MANUAL TRANSMISSION AND DIFFERENTIAL (DIAGNOSTICS)
Check
Is the resistance 1 MΩ or
more?
Is the voltage 2.35 — 2.65 V?
Is the voltage 3.3 — 3.7 V?
Is the voltage 1.3 — 1.7 V?
6MT(diag)-41
Yes No
Go to step 8. Repair the short
circuit of the har-
ness between the
driver's control
center differential
control module and
yaw rate & lateral
G sensor.
Go to step 9. Replace the yaw
rate & lateral G
sensor.
Go to step 10.
Replace the yaw
rate & lateral G
sensor.

properly. A tempo-
rary poor contact of
connector or har-
ness may be the
cause. Repair the
harness or con-
nectors between
the driver's control
center differential
control module and
yaw rate & lateral
G sensor.
