STEP 1. Measure the voltage at ETACS-ECU power supply.
(1) Disconnect ETACS-ECU connector D-11 and measure the
harness side.
(2) Measure the Voltage between terminal 2 and ground.
• The measured value should be approximately 12 volts
(battery positive voltage).
Q: Does the measured voltage correspond with this range?
YES : Replace the ETACS-ECU. The functions, which are
described in the "Technical Description (comment),"
should work normally.
NO : Go to Step 2.
STEP 2. Check ETACS-ECU connector D-11 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector D-11 in good condition?
YES : Go to Step 3.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. The functions, which
are described in the "Technical Description
(comment)," should work normally.
STEP 3. Check the harness wires between ETACS-ECU
connector D-11 (terminal No.2) and fusible link No.8.

NOTE: After checking junction block connector D-01 and OD or
storage connector A-54X, check the wires. If junction block
connector D-01 and OD or storage connector A-54X are dam-
aged, repair or replace them. Refer to GROUP 00E, Harness
Connector Inspection
.
Q: Are the harness wires between ETACS-ECU connector
D-11 (terminal No.2) and fusible link No.8 in good
condition?
YES : There is no action to be taken.
NO : Repair them. The functions, which are described in
the "Technical Description (comment)," should work
normally.
