STEP 2. Check the input signal by using "DATA LIST" 
menu of the SWS monitor.

Turn the ignition switch to the "ON" position before checking 
input signals from the ignition switch (IG1).
(1) Operate the scan tool MB991958 according to the 

procedure below to display "ETACS ECU."
a. Select "Interactive Diagnosis."
b. Select "System Select."
c. Select "SWS."
d. Select "SWS MONITOR."
e. Select "Data List."
f. Select "ETACS ECU."

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

described in the table below.

Q: Does the scan tool MB991958 display "IG SW (IG1)" as 

normal condition?
YES : 
Go to Step 3.
NO :  Refer to Inspection Procedure M-2 "ETACS-ECU 

does not receive any signal from the ignition switch 
(IG1) 

P.54B-490

."

STEP 3. Check power window relay connector C-203 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.

Q: Is power window relay connector C-203 in good 

condition?
YES : 
Go to Step 4.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. The power windows function should now 

work normally.

ITEM NO.

STEP 4. Check the power window relay.

Q: Is the power window relay normal?

YES : Go to Step 5.
NO :  Replace the power window relay. Verify that the 

power windows work normally.

STEP 5. Check the battery power supply circuit to the 
power window relay. Measure the voltage at power window 
relay connector C-203.

(1) Disconnect power window relay connector C-203 and 

measure the voltage available at the junction block side of 

the connector.

(2) Measure the voltage between terminal 5 and ground.

• The voltage should measure approximately 12 volts 

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
YES : 
Go to Step 7.
NO :  Go to Step 6.

STEP 6. Check the wiring harness between power window 
relay connector C-203 (terminal 5) and fusible link (5).

NOTE: Also check junction block connector C-212 for loose, 
corroded or damaged terminals, or terminals pushed back in 
the connectors. If junction block connector C-212 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 power window relay 

connector C-203 (terminal 5) and fusible link (5) 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. The power 
windows function should now work normally.

STEP 7. Check the ground circuit to the power window 
relay. Measure the resistance at power window relay 
connector C-203.

(1) Disconnect power window relay connector C-203 and 

measure the resistance available at the junction block side 

of the connector.

(2) Measure the resistance value between terminal 3 and 

ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 9.
NO :  Go to Step 8.

STEP 8. Check the wiring harness between power window 
relay connector C-203 (terminal 3) and ground.
