Lancer L4-2.4L SOHC (2005)
Q: Is the wiring harness between ETACS-ECU connector C-226 (terminal 8) and the ignition switch (IG1) 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. If the functions or equipment, which are described in "CIRCUIT OPERATION", work normally,
the interior light loaded signal should be normal.
STEP 6. Check the ignition switch (ACC) line of the power supply circuit to the ETACS-ECU. Measure the voltage at ETACS-ECU connector
C-226.
1. Disconnect ETACS-ECU connector C-226 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 4 and ground.
-
The voltage should equal approximately 12 volts (battery positive voltage).
Q: Is the measured voltage approximately 12 volts (battery positive voltage)?
YES: Replace the ETACS-ECU. If the functions or equipment, which are described in "CIRCUIT OPERATION", work normally, the interior
light loaded signal should be normal.
NO: Go to Step 7.
