STEP 2. Check the input signal by using "DATA LIST"
menu of the SWS monitor.
(1) Turn the ignition switch to the "ON" position before checking

input signals from the ignition switch (IG1).

(2) Operate scan tool MB991502 according to the procedure

below to display "ETACS ECU."

1. Select "SYSTEM SELECT."
2. Select "SWS."
3. Select "SWS MONITOR."
4. Select "DATA LIST."
5. Select "ETACS ECU."

(3) Check that normal conditions are displayed on the item

described in the table below.

Q: Is the scan tool display "IG SW (IG1)" as normal

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

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

P.54Bc-7

."

STEP 3. Check the power window relay.
Properly identify and remove the relay from the under-dash
junction block and test the relay using the chart as a guide.

Q: Is the power window relay in good condition?

YES : Go to Step 4.
NO : Replace the power window relay. Verify that the

power windows function should now work normally.

ITEM NO.

STEP 4. Measure at power window relay connector D-219
in order to check the fusible link (4) line of power supply
system to power window relay.
(1) Disconnect power window relay connector D-219, and

measure at the junction block side.

(2) Measure the voltage between terminal numbers 3, 5 and

ground.

• The voltage should be 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 5.

STEP 5. Check power window relay connector D-219 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is power window relay connector D-219 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

. Verify that the power windows function

should now work normally.

STEP 6. Check the wiring harness between power window
relay connector D-219 (terminal 5) and fusible link (4).

NOTE: Also check junction block connector D-221 and inter-
mediate connector D-28 for loose, corroded or damaged termi-
nals, or terminals pushed back in the connectors. If junction
block connector D-221 or intermediate connector D-28 is dam-
aged, 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 D-219 (terminal 5) and fusible link (4) 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 power windows function should now work
normally.

STEP 7. Check the ground circuit to the power window
main switch. Test at power window main switch connector
H-05.
(1) Disconnect power window main switch connector H-05 and

measure the resistance available at the harness side.

(2) Measure the resistance value between terminal 3 and

ground.

• The resistance should equal 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 10.
NO : Go to Step 8.

STEP 8. Check power window main switch connector H-05
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is power window main switch connector H-05 in good

condition?
YES : Go to Step 9.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection
