CHASSIS ELECTRICAL
54A-809
Inspection Procedure 8: ETACS-ECU does not receive any signal from the rear door switch (RH).
.
TECHNICAL DESCRIPTION (COMMENT)
If there is an error to the rear door switch (RH) input
signal, the rear door switch (RH) signal is no longer
output to the communication line.
.
TROUBLESHOOTING HINTS
• The rear door switch (RH) may be defective
• 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
Required Special Tools:
• MB991223: Harness Set
• MB992006: Extra Fine Probe

STEP 1. Check rear door switch (RH) connector D-07 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is rear door switch (RH) connector D-07 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 rear door
switch (RH) is normal.
STEP 2. Check the rear door switch (RH).
Remove the rear door switch (RH). Then check the continuity
between the switch terminals and the switch body.
Q: Is the rear door switch in good condition?
YES : Go to Step 3.
NO : Replace the rear door switch (RH). Check that the
input signal of rear door switch (RH) is normal.
STEP 3. Measure at the lower metal part of the rear door
switch (RH) in order to check the ground circuit to the rear
door switch (RH).
NOTE: Check that the rear door switch (RH) is grounded to the
vehicle body by means of its mounting screw.
Remove the cap, and measure the resistance value between
the lower metal part and the ground.
• The resistance should equal 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
YES : Go to Step 4.
NO : Check the fit of the switch, and repair if necessary.
Check that the input signal of rear door switch (RH) is
normal.
STEP 4. Check ETACS-ECU connector C-313 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector C-313 in good condition?
YES : Go to Step 5.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
. Check that the input signal of rear door
switch (RH) is normal.

STEP 5. Check the wiring harness between driver's door
switch connector D-07 (terminal 3) and ETACS-ECU
connector C-313 (terminal 8).
Check the input lines for open circuit and short circuit.
Q: Is the wiring harness between rear door switch
connector D-07 (terminal 3) and ETACS-ECU connector
C-313 (terminal 8) in good condition?
YES : Replace the ETACS-ECU. Check that the input signal
of rear door switch (RH) is 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. Check that
the input signal of rear door switch (RH) is normal.
