SYMPTOM PROCEDURES

Malfunction of ETACS-ECU power supply circuit

.

TECHNICAL DESCRIPTION (COMMENT)

If the ETACS-ECU functions do not work at all, the 
ETACS-ECU power supply system, ground system, 
or ETACS-ECU may have a problem.

.

TROUBLESHOOTING HINTS

• The wiring harness or connectors may have 

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

• The ETACS-ECU may be defective

DIAGNOSIS

Required Special Tools:

• MB991223: Harness Set

• MB992006: Extra Fine Probe

STEP 1. Check ETACS-ECU connectors C-315 and C-317 
for loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Is ETACS-ECU connectors C-315 and C-317 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

.

STEP 2. Check the ground circuit to the ETACS-ECU. 
Measure the resistance at ETACS-ECU connectors C-315 
and C-317.
(1) Disconnect ETACS-ECU connector C-315 and C-317 and 

measure the resistance available at the wiring harness side 
of the connector.

(2) Measure the resistance value between ETACS-ECU 

connector C-315 terminal 17 and ground.

• The resistance should be 2 ohms or less.

(3) Measure the resistance value between ETACS-ECU 

connector C-317 terminal 15 and ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 4.
NO :  Go to Step 3.

STEP 3. Check the wiring harness between ETACS-ECU 
connector C-315 (terminal 17) or C-317 (terminal 15) and 
the ground.

• Check the ground wires for open circuit.

Q: Is the wiring harness between ETACS-ECU connector 

C-315 (terminal 17) or C-317 (terminal 15) 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.
