STEP 2. Check the ETACS-ECU input signal from the 
ignition switch (by using the pulse check) (by using 
MB991958).
Check the ETACS-ECU input signal [front door switches and 
ignition switch (IG1)] by using scan tool MB991958.
Check the input signals from the following switches:

• Driver's door switch

• Front passenger's door switch

• ignition switch

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.
(1) Connect scan tool MB991958 to the data link connector.
(2) Operate scan tool MB991958 as follows:

1. Select "SYSTEM SELECT."
2. Select "SWS."
3. Select "PULSE CHECK."

(3) Open the driver’s door or front passenger’s door.
(4) Turn the ignition switch (IG1) to ''ON'' position.
(5) Check that scan tool MB991958 sounds
Q: Does the tone alarm of scan tool MB991958 sound when 

the input signal enters?
YES : Replace the ETACS-ECU and then go to Step 11.
NO <Driver's door switch and passenger’s door switch 
input signal> : Go to Step 5.
NO <Ignition switch input signal> : Go to Step 7.

STEP 3. Check the ETACS-ECU input signal from the 
driver's door switch and passenger’s door switch (by 
using a voltmeter).
(1) Use special tool MB991529 to connect a voltmeter between 

ground terminal 4 or 5 and ETACS-ECU terminal 9 of the 
data link connector.

(2) Check that the voltmeter indicator deflects once when 

driver's door switch or passenger’s door switch operated 
<open (on)/depressed (off)>.

Q: Does the voltmeter indicator deflect?

YES : Go to Step 4.
NO :  Go to Step 5.

STEP 4. Check the input signal from the ignition switch (by 
using a voltmeter).
(1) Use special tool MB991529 to connect a voltmeter between 

ground terminal 4 or 5 and ETACS-ECU terminal 9 of the 
data link connector.

(2) Check that the voltmeter indicator deflects once when the 

ignition switch is operated <ACC - ON>.

Q: Does the voltmeter indicator deflect?

YES : Replace the ETACS-ECU and then go to Step 11.
NO :  Go to Step 7.

STEP 5. Check driver's door switch connector E-33 and 
front passenger’s door switch connector E-46 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Are driver's door switch connector E-33 and front 

passenger’s door switch E-46 in good condition?
YES : Go to step 6.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E 

P.00E-2

, Harness Connector inspection. 

Then go to Step 11.

STEP 6. Check the front door switch.
(1) Remove the driver's door or fornt passenger’s door switch 

(Refer to 

P.52A-42

.).

(2) Follow the table to check the front door switches continuity.

Q: Is the front door switch in good condition?

YES : Go to Step 7 .
NO :  Replace front door switch, then go to Step 11. 

STEP 7. Check ETACS-ECU connector D-11 and D-26 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Are ETACS-ECU connector D-11 and D-26 in good 

condition?
YES : Go to step 8.
NO :  Repair or replace the damaged components. Refer to
