STEP 5. Check the wiring harness between ETACS-ECU
connector C-317 (terminal 10) and theft-alarm sensor
connector D-136 (terminal 1).

• Check the power supply line (battery supply) for open circuit

and short circuit.

NOTE: Also check intermediate connector C-36 and D-135 for
loose, corroded, or damaged terminals, or terminals pushed
back in the connector. If intermediate connector C-36 and
D-135 is damaged, repair or replace the connector as
described in GROUP 00E, Harness Connector Inspection

P.00E-2

.

Q: Is the wiring harness between ETACS-ECU connector

C-317 (terminal 10) and theft-alarm sensor connector
D134 (terminal 1) 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.

STEP 6. Check the wiring harness between ETACS-ECU
connector C-316 (terminal 1) and theft-alarm sensor
connector D-136 (terminal 2).

• Check the communication line for open circuit.

NOTE: Also check intermediate connector D-135 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector D-135 is damaged, repair
or replace the connector as described in GROUP 00E, Harness
Connector Inspection

P.00E-2

.

Q: Is the wiring harness between ETACS-ECU connector

C-316 (terminal 1) and theft-alarm sensor connector
D-136 (terminal 2) 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.

STEP 7. Recheck for diagnostic trouble code.
Check again if the DTC is set to the ETACS-ECU.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Ensure that the ignition switch is at the "LOCK" (OFF)

position.

(2) Start up the personal computer.
(3) Connect special tool MB991827 to special tool MB991824

and the personal computer.

(4) Connect special tool MB991910 to special tool MB991824.
(5) Connect special tool MB991910 to the data link connector.
(6) Erase the DTC.
(7) Turn the ignition switch to the "ON" position.
(8) Check if the DTC is set.
(9) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?

YES : Replace the power window main switch.
NO : A poor connection, open circuit or other intermittent

malfunction is present in the LIN bus lines between
the power window main switch and the ETACS-ECU
(Refer to GROUP 00, How to Cope with Intermittent
Malfunction

P.00-15

).

DTC U150B: Column SW checksum error

.

TROUBLE JUDGMENT

The ETACS-ECU will set DTC U150B when abnor-
mal signals are received from the column switch (col-
umn-ECU).

.

TROUBLESHOOTING HINTS

• The column switch (lighting switch) may be

defective.

DIAGNOSIS

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicles Communication Interface (V.C.I.)

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A (Vehicles with

CAN communication system)
