STEP 1. Check key reminder switch connector C-211 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is key reminder switch connector C-211 in good
condition?
YES : Go to Step 2.
NO : Repair or replace the damaged component(s) (Refer
to GROUP 00E, Harness Connector Inspection
). Check that the input signal of key reminder
switch is normal.
STEP 2. Check the key reminder switch.
Disconnect key reminder switch connector C-211. Then check
continuity between terminals.
Q: Is the key reminder switch in good condition?
YES : Go to Step 3.
NO : Replace the key reminder switch. Check that the input
signal of key reminder switch is normal.
STEP 3. Check the ground circuit to the key reminder
switch. Measure the resistance at key reminder switch
connector C-211.
(1) Disconnect key reminder switch connector C-211 and
measure the resistance available at the wiring harness side
of the connector.
(2) Measure the resistance value between terminal 2 and
ground.
• The resistance should be 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
YES : Go to Step 5.
NO : Go to Step 4.

STEP 4. Check the wiring harness between key reminder
switch connector C-211 (terminal 2) and ground.
Check the ground wires for open circuit.
Q: Is the wiring harness between key reminder switch
connector C-211 (terminal 2) and ground 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. Check that
the input signal of key reminder switch is normal.
STEP 5. Check ETACS-ECU connector C-315 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector C-315 in good condition?
YES : Go to Step 6.
NO : Repair or replace the damaged component(s) (Refer
to GROUP 00E, Harness Connector Inspection
). Check that the input signal of key reminder
switch is normal.
STEP 6. Check the wiring harness between key reminder
switch connector C-211 (terminal 3) and ETACS-ECU
connector C-315 (terminal 13).
Check the output lines for open circuit and short circuit.
Q: Is the wiring harness between key reminder switch
connector C-211 (terminal 3) and ETACS-ECU connector
C-315 (terminal 13) in good condition?
YES : Go to Step 7.
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. Check that
the input signal of key reminder switch is normal.
STEP 7. Check for continuity between key reminder switch
connector C-211 terminal 2 and each of the other terminals
as well as terminal 3 and each of the other terminals.
(1) Disconnect key reminder switch connector C-211 and
measure the resistance available at the equipment side of
the connector.
(2) Check for continuity between key reminder switch
connector C-211 terminal 2 and each of the other terminals
as well as terminal 3 and each of the other terminals.
Q: Does continuity exist between the terminals?
NO : Replace the ETACS-ECU. Check that the input signal
of key reminder switch is normal.
YES : Replace the key reminder switch. Check that the input
signal of key reminder switch is normal.

COMMENTS ON TROUBLE SYMPTOM
The front door lock actuator (LH) or front door lock
actuator (RH) <vehicles with KOS> input signal is
used for the operation judgment of the functions
below. If the signal is abnormal, these functions will
not work normally.
• Key reminder function
• Central door locking
• KOS
• Keyless entry system
• Interior light
.
PROBABLE CAUSES
• The front door lock actuator (LH) may be defec-
tive
• The front door lock actuator (RH) may be defec-
tive <vehicles with KOS>
• The ETACS-ECU may be defective
• The wiring harness or connectors may have
loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector
DIAGNOSIS
