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 

P.00E-2

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 

P.00E-2

.

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 

P.00E-2

. 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 

P.00E-2

.

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 

P.00E-2

. The 

multi-center display unit (middle grade type) should 
work normally.
