STEP 1. Check ETACS-ECU connectors C-218 and C-219 
for loose, corroded  or damaged terminals, or terminals 
pushed back in the connector.
Q: Are ETACS-ECU connectors C-218 and C-219 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

. The system should communicate with the 

ETACS-ECU normally.

STEP 2. Check the battery power supply circuit to the 
ETACS-ECU. Measure the voltage at ETACS-ECU 
connector C-219.
(1) Disconnect ETACS-ECU connector C-219 and measure the 

voltage available at the junction block side of the connector.

(2) Measure the voltage between terminal 20 and ground.

• The voltage should measure approximately 12 volts 

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
YES : 
Go to Step 4.
NO :  Go to Step 3.

STEP 3. Check the wiring harness between ETACS-ECU 
connector C-219 (terminal 20) and the battery.

NOTE: Also check joint connector C-01 and junction block con-
nector C-214 for loose, corroded, or damaged terminals, or ter-
minals pushed back in the connector. If joint connector C-01 or 
junction block connector C-214 are damaged, repair or replace 
the damaged component(s) as described in GROUP 00E, Har-
ness Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between ETACS-ECU connector 

C-219 (terminal 20) and the battery 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. The system 
should communicate with the ETACS-ECU normally.

STEP 4. Check the ground circuit to the ETACS-ECU. 
Measure the resistance at ETACS-ECU connector C-219.
(1) Disconnect ETACS-ECU connector C-219 and measure the 

resistance available at the junction block side of the 
connector.

(2) Measure the resistance value between terminal 3 and 

ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 6.
NO :  Go to Step 5.

STEP 5. Check the wiring harness between ETACS-ECU 
connector C-218 (terminal 56), C-219 (terminal 3) and 
ground.

NOTE: Also check junction block connector C-211 for loose, 
corroded, or damaged terminals, or terminals pushed back in 
the connector. If junction block connector C-211 is damaged, 
repair or replace the damaged component(s) as described in 
GROUP 00E, Harness Connector Inspection

.

Q: Is the wiring harness between ETACS-ECU connector 

C-218 (terminal 56), C-219 (terminal 3) and ground 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. The system
