Q: Is ETACS-ECU connector C-317 in good condition?
YES : Go to Step 2.
NO : Repair or replace the damaged component(s). Check that the input signal of ignition switch (ACC) is normal.
STEP 2. Check the ignition switch (ACC) line of the power supply circuit to the ETACS-ECU. Measure the voltage at ETACS-ECU connector
C-317.
1. Disconnect ETACS-ECU connector C-317 and measure the voltage available at the junction block side of the connector
2. Turn the ignition switch to the "ACC" position.
3. Measure the voltage between terminal 7 and ground.
-
The voltage should measure approximately 12 volts (battery positive voltage).
Q: Is the measured voltage approximately 12 volts (battery positive voltage)?
YES : Go to Step 5.
NO : Go to Step 3.
STEP 3. Check the ignition switch.
Remove the ignition switch. Then check continuity between the switch terminal.
