STEP 3. Check ETACS-ECU connector D-222 and D-224 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Are ETACS-ECU connector D-222 and D-224 in good 

condition?
YES : Go to Step 4.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. The system should communicate with the 

SWS monitor normally.

STEP 4. Check the ground circuit to the ETACS-ECU. Test 
at ETACS-ECU connector D-222 and D-224.
(1) Disconnect ETACS-ECU connector D-222 and D-224, and 

measure the resistance available at the junction block side 
of the connector.

(2) Measure the resistance value between ETACS-ECU 

connector D-222 terminal 20 and ground, and also between 
ETACS-ECU connector D-224 terminal 23 and ground.

• The resistance should equal 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 D-222 (terminal 20) or D-224 (terminal 23) and 
the ground.

NOTE: Also check junction block connector D-209 for loose, 
corroded, or damaged terminals, or terminals pushed back in 
the connector. If junction block connector D-209 is damaged, 
repair or replace the damaged component(s) as described in 
GROUP 00E, Harness Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between ETACS-ECU connector 

D-222 (terminal 20) or D-224 (terminal 23) and the 
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 
should communicate with the SWS monitor kit 
normally.

STEP 6. Check data link connector D-118 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is and data link connector D-118 in good condition?
