TER DIFFERENTIAL CONTROL DIAL, Diag-
nostic Procedure with Diagnostic Trouble Code
(DTC).>
8 CHECK PARKING BRAKE SWITCH.

ING BRAKE SWITCH, Diagnostic Procedure
with Diagnostic Trouble Code (DTC).>
MANUAL TRANSMISSION AND DIFFERENTIAL (DIAGNOSTICS)
Check
Does the AUTO indicator light
illuminate?
Is the resistance less than 1 Ω? Go to step 3.
Is the fuse (No. 11) blown out? Replace the fuse
Is the voltage 10 V or more?
Does it change to manual
mode?
Does the driver's control center
differential indicator light illumi-
nate according to the dial?
Is the center differential control
dial circuit normal?
Is the parking brake switch cir-
cuit normal?
6MT(diag)-29
Yes No
Go to step 5. Go to step 2.
Repair the open
circuit of the
driver's control
center differential
control module
ground circuit.
Go to step 4.
(No. 11). If the
replaced fuse (No.
11) has blown out
easily, repair the
short circuit of har-
ness between fuse
(No. 11) and
driver's control
center differential
control module.
Go to step 5. Repair the open
circuit of harness
between fuse (No.
11) and the driver's
control center dif-
ferential control
module, or fuse
(No. 11) and bat-
tery.
Go to step 6. Repair. <Ref. to
