STEP 2. Check the ground circuit to the multivision display 
connector. Measure the resistance at multivision display 
connector C-10, C-07 and C-09 <vehicles with rear display 
unit>.
(1) Disconnect multivision display connector C-10, C-07 and 

C-09 <vehicles with rear display unit>, and measure the 
resistance available at the wiring harness side of the 
connector.

(2) Measure the resistance between multivision display 

connector C-10 terminal 9 and ground.

OK: The resistance should be 2 ohms or less

(3) Measure the resistance between multivision display 

connector C-07 terminal 65 and ground.

OK: The resistance should be 2 ohms or less

(4) Measure the resistance between multivision display 

connector C-09 <vehicles with rear display unit> terminal 25 
and ground.

OK: The resistance should be 2 ohms or less

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 4.
NO :  Go to Step 3.

STEP 3. Check the wiring harness between multivision 
display connector C-10 (terminal 9), C-07 (terminal 65) and 
C-09 <vehicles with rear display unit> (terminal 25) and 
ground.

• Check the ground wire for open circuit.

NOTE: Also check intermediate connector C-17, C-19 and 
D-123 <vehicles without rear display unit> for loose, corroded, 
or damaged terminals, or terminals pushed back in the connec-
tor. If intermediate connector C-17, C-19 and D-123 <vehicles 
without rear display unit> is damaged, repair or replace the 
connector as described in GROUP 00E, Harness Connector 
Inspection 

P.00E-2

.

Q: Is the wiring harness between multivision display 

connector C-10 (terminal 9) and ground in good 
condition?
YES : The trouble can be an intermittent malfunction (Refer 

to GROUP 00, How to use 
Troubleshooting/inspection Service Points, How to 
Cope with Intermittent Malfunction 

P.00-15

).

NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary. 

STEP 4. Using scan tool MB991958, read the ETACS-ECU 
diagnostic trouble code. 
Check if the diagnostic trouble code is set to the ETACS-ECU.
Q: Is the check result normal?

YES : Troubleshoot the ETACS-ECU. Refer to Diagnosis 

P.54A-732

.

NO :  Go to Step 5.

STEP 5. Check ETACS-ECU connector C-317 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is ETACS-ECU connector C-317 in good condition?

YES : Go to Step 6.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

.

STEP 6. Check the wiring harness between ETACS-ECU 
connector C-317 (terminal 1) and multivision display 
connector C-10 (terminal 17).

• Check the power supply line (battery supply) for open circuit 

and short circuit.

NOTE: Also check intermediate connector C-17 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connector C-17 is damaged, repair or 
replace the connector as described in GROUP 00E, Harness 
Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between ETACS-ECU connector 

C-317 (terminal 1) and multivision display connector 
C-10 (terminal 17) in good condition?
YES : Go to Step 7.
NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary. 

STEP 7. Check multivision display connector C-09 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Is multivision display connector C-09 in good 

condition?
YES : Go to Step 8.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

.

STEP 8. Check the wiring harness between ETACS-ECU 
connector C-317 (terminal 1) and multivision display 
connector C-09 (terminal 21).

• Check the power supply line (battery supply) for open circuit 

and short circuit.

NOTE: Also check intermediate connector C-19 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connector C-19 is damaged, repair or 
replace the connector as described in GROUP 00E, Harness 
Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between ETACS-ECU connector 

C-317 (terminal 1) and multivision display connector 
C-09 (terminal 21) in good condition?
YES : Go to Step 9.
NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged

STEP 9. Using scan tool MB991958, check data list.
Check the input signal of ACC relay.

• Turn the ignition switch to the ACC position.

OK: Normal condition is displayed.

Q: Is the check result normal?

YES : Go to Step 10.
NO :  Refer to Inspection Procedure 1 "The ignition switch 

(ACC) signal is not received

."

STEP 10. Check ETACS-ECU connector C-309 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is ETACS-ECU connector C-309 in good condition?

YES : Go to Step 11.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. The steering remote control switch should 

work normally.

STEP 11. Check the power supply circuit to the 
ETACS-ECU. Measure the voltage at ETACS-ECU 
connector C-309.
(1) Disconnect the connector, and measure at the wiring 

harness-side connector.

(2) Turn the ignition switch to the "ACC" position.
(3) Measure the voltage between terminal 2 and ground.

OK: The voltage should measure approximately 12 
volts (battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
