STEP 10. Check the wiring harness between ETACS-ECU 
connector C-219 (terminal 3) and ground.

NOTE: Also check  connector C-211, check the wires. If  con-
nector C-211 is damaged, repair or replace them. Refer to 
GROUP 00E, Harness Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between ETACS-ECU connector 

C-219 (terminal 3) and ground in good condition?
YES : 
There is no action to be taken.
NO :  Repair the wiring harness. Confirm that diagnostic 

tool MB991958 communicates normally.

STEP 11. Check the CAN_H line (communication line 
including the ETACS-ECU) between joint connector (3) and 
the ETACS-ECU connector for a short to the power supply. 
Measure the voltage at joint connector (3) C-02.

CAUTION

A digital multimeter should be used. For details refer to 

P.54C-4

.

CAUTION

The test wiring harness should be used. For details refer to 

P.54C-4

.

(1) Disconnect joint connector (3) C-02, and measure the 

voltage at the wiring harness side of joint connector (3) 
C-02.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between joint connector (3) terminal 5 

and body ground.

OK: 4.0 V or less

Q: Does the voltage measure 4.0 V or less?

YES : If the voltage measures 4.0 V or less, go to Step 14.
NO :  If the voltage measures more than 4.0 V, go to Step 

12.

STEP 12. Check ETACS-ECU connector C-218 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.

CAUTION

The strand end of the twisted wire should be within 10 cm 
(4 inches) from the connector. For details refer to 

P.54C-4

.

Q: Is ETACS-ECU connector C-218 in good condition?

YES : Go to Step 13.
NO :  Repair the damaged parts.

STEP 13. Check the CAN_H line (communication line only) 
between joint connector (3) and ETACS-ECU connector for 
a short to the power supply. Measure the voltage at joint 
connector (3) C-02.

CAUTION

A digital multimeter should be used. For details refer to 

P.54C-4

.

CAUTION

The test wiring harness should be used. For details refer to 

P.54C-4

.

(1) Disconnect joint connector (3) C-02 and ETACS-ECU 

connector C-218, and measure the voltage at the wiring 
harness side of joint connector (3) C-02.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between joint connector (3) terminal 5 

and body ground.

OK: 1.0 V or less

CAUTION

Strictly observe the specified wiring harness repair proce-
dure. For details refer to 

P.54C-5

.

Q: Does the voltage measure 1.0 V or less?

YES : If the voltage measures 1.0 V or less, diagnose CAN 

bus lines thoroughly by referring to 

P.54C-31

 without 

multi-centre display or 

P.54C-81

 with multi-centre 

display.

NO :  If the voltage measures more than 1.0 V, repair the 

wiring harness between joint connector (3) and the 
ETACS-ECU connector.
