STEP 1. Check the multi-center display unit (middle grade
type) ground circuit. Measure the resistance at the
multi-center display unit (middle grade type) connector
C-05.
(1) Disconnect the multi-center display unit (middle grade type)
connector C-05 and measure at the harness side.
(2) Measure the resistance between terminal 6 and ground.
• The measured value should be 2 ohm or less.
Q: Does the measured resistance value correspond with
this range?
YES : Go to Step 4.
NO : Go to Step 2.
STEP 2. Check the multi-center display unit (middle grade
type) connector C-05 for loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Q: Is the multi-center display unit (middle grade type)
connector C-05 in good condition?
YES : Go to Step 3.
NO : Repair or replace the connector. Refer to GROUP
00E, Harness Connector Inspection

STEP 3. Check the wiring harness between multi-center
display unit (middle grade type) connector C-05 (terminal
6) and ground.
NOTE: After checking joint connector (2) C-03 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. check the wires. If joint connector (2) C-03 is dam-
aged, repair or replace the wiring harness. Refer to GROUP
00E, Harness Connector Inspection
Q: Is the wiring harness between multi-center display unit
(middle grade type) connector C-05 (terminal 6) and
ground in good condition?
YES : There is no action to be taken.
NO : Repair the wiring harness. The multi-center display
unit (middle grade type) should work normally.
STEP 4. Check the multi-center display unit (middle grade
type) power supply circuit (battery). Measure the voltage at
the multi-center display unit (middle grade type) connector
C-05.
(1) Disconnect the multi-center display unit (middle grade type)
connector C-05 and measure at the harness side.
(2) Measure the voltage between terminal 1 and ground.
• The measured value should be approximately 12 volts
(battery positive voltage).
Q: Does the measured voltage correspond with this range?
YES : Go to Step 7.
NO : Go to Step 5.

STEP 5. Check multi-center display unit (middle grade
type) connector C-05 for loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Q: Is multi-center display unit (middle grade type)
connector C-05 in good condition?
YES : Go to Step 6.
NO : Repair or replace the connector. Refer to GROUP
00E, Harness Connector Inspection
. The
multi-center display unit (middle grade type) should
work normally.
STEP 6. Check the wiring harness between C-05 (terminal
1) and battery.
NOTE: Also check intermediate connector C-29 and joint con-
nector (1) C-01 for loose, corroded, or damaged terminals, or
terminals pushed back in the connector. If intermediate connec-
tor C-29 and joint connector (1) C-01 is damaged, repair or
replace the wiring harness. Refer to GROUP 00E, Harness
Connector Inspection
.
Q: Is the wiring harness between C-05 and battery in good
condition?
YES : There is no action to be taken.
NO : Repair the wiring harness. The multi-center display
unit (middle grade type) should work normally.

STEP 7. Check the multi-center display unit (middle grade
type) power supply circuit [ignition switch (ACC)]. Measure
the voltage at the multi-center display unit (middle grade
type) connector C-05.
(1) Disconnect the multi-center display unit (middle grade type)
connector C-05 and measure at the harness side.
(2) Turn the ignition switch to "ACC" position.
(3) Measure the voltage between terminal 3 and ground by
backprobing.
• The measured value should be approximately 12 volts
(battery positive voltage).
Q: Does the measured voltage correspond with this range?
YES : Go to Step 10.
NO : Go to Step 8.
STEP 8. Check multi-center display unit (middle grade
type) connector C-05 for loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Q: Is multi-center display unit (middle grade type)
connector C-05 in good condition?
YES : Go to Step 9.
NO : Repair or replace the connector. Refer to GROUP
00E, Harness Connector Inspection
. The
multi-center display unit (middle grade type) should
work normally.
