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
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.
