Step 29. Resistance measurement at E-09 rear
power window regulator motor (LH) connector
(1) Disconnect the connector, and measure at the
wiring harness side.
(2) Resistance between E-09 rear power window
regulator motor (LH) connector terminal No.5 and
body earth.
OK: 2
Ω or less
Q: Is the check result normal?
YES :
Go to Step 31.
NO :
Go to Step 30.
Step 30. Check the wiring harness from E-09 rear
power window regulator motor (LH) connector
terminal No.5 to body earth.
NOTE:
Prior to the wiring harness inspection, check interme-
diate connector D-15, and repair if necessary.
• Check the input and output lines to the revolution
detection sensor for open or short circuit.
Q: Is the check result normal?
YES :
Go to Step 31.
NO :
Repair the wiring harness.

Step 31. Connector check: E-08 rear power
window sub switch (LH) connector
Q: Is the check result normal?
YES :
Go to Step 32.
NO :
Repair the defective connector.
Step 32. Check the wiring harness from E-08 rear
power window sub switch (LH) connector
terminal Nos.8, 2 and 3 to E-09 rear power
window regulator motor (LH) connector terminal
Nos.3, 2 and 6.
• Check the input and output lines to the revolution
detection sensor for open or short circuit.
Q: Is the check result normal?
YES :
Go to Step 33.
NO :
Repair the wiring harness.
Step 33. Retest the system.
After the rear power window sub switch (LH) is
replaced, check that the rear left door anti-trap func-
tion can be operated by the power window sub
switch.
(1) Replace the rear power window sub switch (LH).
(2) Check that the rear left power window anti-trap
function works.
Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00
− How to
Cope with Intermittent Malfunction
NO :
Replace the rear power window regulator
motor assembly (LH).

KEYLESS ENTRY SYSTEM
INSPECTION PROCEDURE E-1: Keyless entry system does not work.
CAUTION
Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.
COMMENTS ON TROUBLE SYMPTOM
If the keyless entry system does not work normally,
the input signal circuits to the components below or
the ETACS-ECU may be defective.
• Key reminder switch
• All of the door switches
• Keyless entry transmitter
• Driver's door lock actuator
POSSIBLE CAUSES
• Malfunction of the key reminder switch
• Malfunction of the door switches
• Malfunction of the keyless entry transmitter
• Malfunction of the driver's door lock actuator
• Malfunction of the ETACS-ECU
• Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Check the power supply circuit.
When the ignition switch is turned to the LOCK
(OFF) position, check if the hazard warning lamps
illuminate.
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Refer to inspection procedure A-2 "Check

Step 2. Pulse check
Check the input signals below which are related to
the keyless entry system.
OK: The M.U.T.-II/III sounds or the voltmeter
needle fluctuates.
Q: Is the check result normal?
All the signals are received normally. :
Go to Step
3.
The key reminder switch signal is not received. :
Refer to inspection procedure L-8 "The key
reminder switch signal is not received
."
All the door switch signals are not received. :
Refer to inspection procedure L-10 "All the
door switch signals are not received <LH
drive vehicles>
inspection procedure L-10 "All the door
switch signals are not received <RH drive
vehicles>
The driver's door lock actuator switch signal is not
received. :
Refer to inspection procedure L-11
"The front door lock actuator (LH) switch
signal is not received <LH drive
vehicles>
." Refer to inspection
procedure L-11 "The front door lock actuator
(RH) switch signal is not received <RH drive
vehicles>
The keyless entry transmitter switch signal is not
received. :
Refer to inspection procedure L-13
"Each switch signal of the keyless entry
transmitter is not received
Step 3. Retest the system.
Check the keyless entry system works normally.
Q: Is the check result normal?
YES :
