STEP 12. Check the wiring harness between ETACS-ECU
connector C-301 and body ground for a short to power
supply. Measure the voltage at ETACS-ECU connector
C-301.
(1) Disconnect ETACS-ECU connector C-301, and measure

the voltage at the wiring harness side of ETACS-ECU
connector.

(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between ETACS-ECU connector

terminal 6 and body ground.

OK: 4.7 volts or less

(4) Measure the voltage between ETACS-ECU connector

terminal 7 and body ground.

OK: 4.7 volts or less

Q: Do all the voltages measure 4.7 volts or less?

YES : Go to Step 23.
NO : Go to Step 13.
