TROUBLE JUDGMENT
The  ETACS-ECU  will  set  DTC  U1515  when  no
communication has been carried out for more than a
certain period after the slave task received last valid
data.

TROUBLESHOOTING HINTS

｠

The ETACS-ECU may be defective.

｠

The slave ECU may be defective.

｠

LIN bus lines shorted to power supply

｠

LIN bus lines shorted to ground

DIAGNOSIS

Required Special Tools:

｠

MB991223: Harness Set

｠

MB992006: Extra Fine Probe

｠

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)

STEP 1. Check the following connectors.
Check the following connectors:

｠

Column switch connector C-212

｠

ETACS-ECU connectors C-301 and C-316

｠

Sunroof motor assembly connector D-04

｠

Power window main switch connector E-19

Q:Are all the connectors 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.

DIAGNOSIS

STEP 2. Check the following wiring harness.
Check the wiring harness between the following connectors:

｠

Wiring harness from ETACS-ECU connector C-301 (terminal
1) to column switch connector C-212 (terminal 3)

｠

Wiring harness from ETACS-ECU connector C-301 (terminal
1) to power window main switch connector E-19 (terminal 7)

｠

Wiring harness from ETACS-ECU connector C-316 (terminal
1) to sunroof motor assembly connector D-04 (terminal 7)

NOTE: 

Also check intermediate connector C-127 for loose,

corroded, or damaged terminals, or terminals pushed back in
the connector. If intermediate connector C-127 is damaged,
repair or replace the damaged component(s) as described in
GROUP 00E, Harness Connector Inspection P.00E-2.

Q:Are all the wiring harness wires in good condition?

YES:

 Go to Step 3.

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 3. Measure the voltage at the LIN bus lines.
Check the LIN bus lines for short to power supply.

(1)

Disconnect all the connectors which are connecter to the LIN
bus lines.

(2)

Turn the ignition switch from "LOCK" (OFF) to "ON" position .

Connector C-212 
(Harness side)

(3)

Measure  the  voltage  between  column  switch  connector
C-212 (terminal 3) and ground.

｠

The voltmeter needle does not swing.

NOTE: 

If the LIN bus lines are short to power supply,

the voltmeter indicates a constant value.

ZC5010400025

Connector D-04 
(Harness side)

(4)

Measure  the  voltage  between  sunroof  motor  assembly
connector D-04 (terminal 7) and ground.

｠

The voltmeter needle does not swing.

NOTE: 

If the LIN bus lines are short to power supply,

the voltmeter indicates a constant value.

Q:Is the check result normal?

YES:

 Go to Step 4.

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 4. Measure the resistance at the LIN bus lines.
Check the LIN bus lines for short to ground.

(1)

Disconnect all the connectors which are connecter to the LIN
bus lines.
