Step
9 CHECK HARNESS CONNECTOR BETWEEN
DRIVER'S CONTROL CENTER DIFFEREN-
TIAL CONTROL MODULE AND DATA LINK
CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the driver's control center differ-
ential control module connector.
3) Measure the resistance between the
driver's control center differential control mod-
ule connector and data link connector.
Connector & terminal
(B380) No. 9 — (B40) No. 7:
10 CHECK POWER SUPPLY CIRCUIT.
1) Turn the ignition switch to ON. (engine OFF)
2) Measure the ignition power supply voltage
between the driver's control center differential
control module connector and chassis ground.

Check
Is the resistance less than 1 Ω? Go to step 10.
Is the voltage 10 V or more?
Is the resistance less than 1 Ω? Repair the connec-

Yes No
Repair the harness
and connector
between the
driver's control
center differential
control module and
data link connec-
tor.
Go to step 11. Repair the harness
open circuit
between the
driver's control
center differential
control module and
the battery.
Repair the open
tor. circuit in harness
between driver's
control center dif-
ferential control
module and inhibi-
tor side connector,
and poor contact of
coupling connec-
tor.
