2005 MITSUBISHI 380 warning

INPUT SIGNAL PROCEDURES
SIMPLIFIED WIRING SYSTEM (SWS)54B-437
STEP 2. Check the hazard warning lamp switch.
Remove the hazard warning lamp switch. Refer to GROUP
54A, Hazard Warning Light Switch P.54A-168. Then check
continuity between the switch terminals.
Q: Is the hazard warning lamp switch in good condition?
YES : Go to Step 3.
NO : Replace the hazard warning lamp switch. If the
equipment described in "CIRCUIT OPERATION",
work normally the input signal from the hazard
warning lamp switch should be normal.
STEP 3. Check the ground circuit to the hazard warning
lamp switch. Measure the resistance at hazard warning
lamp switch connector C-08.
(1) Disconnect hazard warning lamp switch connector C-08
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. SWITCH

STEP 4. Check the wiring harness between hazard warning
lamp switch connector C-08 (terminal 2) and ground.
Q: Is the wiring harness between hazard warning lamp
switch connector C-08 (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. If the
equipment described in "CIRCUIT OPERATION" work
normally, the input signal from the hazard warning
lamp switch should be normal.
STEP 5. Check ETACS-ECU connector C-218 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector C-218 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. If the equipment described in "CIRCUIT
OPERATION" work normally, the input signal from the
hazard warning lamp switch should be normal.

STEP 6. Check the wiring harness between hazard warning
lamp switch connector C-08 (terminal 1) and ETACS-ECU
connector C-218 (terminal 49).
Q: Is the wiring harness between hazard warning lamp
switch connector C-08 (terminal 1) and ETACS-ECU
connector C-218 (terminal 49) in good condition?
YES : Replace the ETACS-ECU. If the equipment described
in "CIRCUIT OPERATION" work normally, the input
signal from the hazard warning lamp switch should be
normal.
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. If the
equipment described in "CIRCUIT OPERATION" work
normally, the input signal from the hazard warning
lamp switch should be normal.

SIMPLIFIED WIRING SYSTEM (SWS)54B-440
INSPECTION PROCEDURE N-3: ETACS-ECU does not receive any signal from any of the door
switches.
.
CIRCUIT OPERATION
The ETACS-ECU operates the following functions or
systems according to signal from the front or rear
door switches:
Light reminder tone alarm function switch (RH)>
Door ajar warning buzzer
Ignition key reminder tone alarm switches>
Power window timer function switches>
Sunroof timer function
Headlamp automatic shutdown function door switch (RH)>
Keyless entry system
Timer lock
Dome lamp
Interior lamp automatic-shutdown function door switches>
Ignition key hole illumination lamp switch (RH)>
Door-ajar indicator lamp
.
TECHNICAL DESCRIPTION (COMMENT)
If the signal is not normal, the functions or systems
described in "CIRCUIT OPERATION" do not work
normally. If the signal is not normal, the front or rear
door switches or the ETACS-ECU may be defective.
.
TROUBLESHOOTING HINTS
Refer to circuit diagrams GROUP-90
Refer to configuration diagrams GROUP-80
The front or rear door switches may be defective
The wiring harness or connectors may have
loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector
The ETACS-ECU may be defective
