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 

P.00E-2

. 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 

P.00E-2

. 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.

Inspection Procedure 9: ETACS-ECU does not receive any signal from the liftgate switch.

TECHNICAL DESCRIPTION (COMMENT)

If there is an error to the liftgate switch input signal, 
the liftgate switch signal is no longer output to the 
communication line.

.

TROUBLESHOOTING HINTS

• The liftgate switch 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 liftgate switch connector F-12 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector. 
Q: Is liftgate switch connector F-12 in good condition?

YES : Go to Step 2.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Check that the input signal of liftgate switch 

is normal.

STEP 2. Check the liftgate switch.
Remove the liftgate switch. Then check the continuity between 
the switch terminals and the switch body.

Q: Is the liftgate switch in good condition?

YES : Go to Step 3.
NO :  Replace the liftgate switch. Check that the input signal 

of liftgate switch is normal.
