."
Step 2. Connector check: C-219 ETACS-ECU
connector
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Repair the connector.
Step 3. Voltage measurement at the C-219
ETACS-ECU connector.
(1) Remove the ETACS-ECU, and measure at the
junction block side.
(2) Check the voltage between the C-219
ETACS-ECU connector terminal No.2 and body
earth.
OK: Battery positive voltage
Q: Is the check result normal?
YES :
Go to Step 5.
