STEP 3. Check ETACS-ECU connector C-219, junction 
block connectors C-214 and C-204 for loose, corroded or 
damaged terminals, or terminals pushed back in the 
connector.

Q: Are ETACS-ECU connector C-219, junction block 

connectors C-214 and C-204 in good condition?
YES : 
Replace the ETACS-ECU. Verify that the turn-signal 

lights illuminate normally.

NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Verify that the turn-signal lights illuminate 

normally.

STEP 4. Check ETACS-ECU connector C-219 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.

Q: Is ETACS-ECU connector C-219 in good condition?

YES : Go to Step 5.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Verify that the turn-signal lights illuminate 

normally.

STEP 5. Check the battery power supply circuit to the 
ETACS-ECU. Measure the voltage at ETACS-ECU 
connector C-219.

(1) Disconnect ETACS-ECU connector C-219, and measure 

the voltage available at the junction block side of the 

connector.

(2) Measure the voltage between terminal 11 and ground.

• The voltage should measure approximately 12 volts 

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
YES : 
Replace the ETACS-ECU. Verify that the turn-signal 

lights illuminate normally.

NO :  Go to Step 6.

STEP 6. Check the wiring harness between ETACS-ECU 
connector C-219 (terminal 11) and the battery.

NOTE: Also check junction block connector C-214 for loose, 
corroded, or damaged terminals, or terminals pushed back in 
the connector. If junction block connector C-214 is damaged, 
Repair or replace the damaged component(s) as described in 
GROUP 00E, Harness Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between ETACS-ECU connector 

C-219 (terminal 11) and the battery in good condition?
YES : 
No action is necessary and testing is complete.
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. Verify that 
the turn-signal lights illuminate normally.

STEP 7. Check the input signal by using "FUNCTION 
DIAG." menu of the SWS monitor.

Check the input signals from the following switches:

• Ignition switch: ON

• Turn-signal light switch: RH

CAUTION

To prevent damage to scan tool MB991958, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958. Connect 
special tool MB991910 before connecting special tool 
MB991812. Be sure to connect special tool MB991806 after 
turning on special tool MB991824.
(1) Connect the special tool. Refer to "How to connect SWS 

monitor 

P.54B-13

."

(2) Turn the ignition switch to the "LOCK" (OFF) position.
(3) Operate scan tool MB991958 according to the procedure 

below to display "TURN SIG.RH."
a. Select "Interactive Diagnosis."
b. Select "System select."
c. Select "SWS."
d. Select "SWS MONITOR."
e. Select "Function Diag."
f. Select "TURN SIGNAL."
g. Select "TURN SIG.RH."

(4) Check that normal conditions are displayed for the items 

described in the table below.

Q: Does the scan tool MB991958 display the items "T/S RH 

SW" and "IG SW (IG1)" as normal condition?
Normal conditions are displayed for all the items : 
Go to 

Step 8.

Normal condition is not displayed for "T/S RH SW" : 

Refer to Inspection Procedure M-5 "ETACS-ECU 
does not receive any signal from the turn-signal light 
switch 

P.54B-505

."

Normal condition is not displayed for "IG SW (IG1)" : 

Refer to Inspection Procedure M-2 "ETACS-ECU 
does not receive any signal from the ignition switch 
(IG1) 

P.54B-490

."

ITEM NO.
