Lancer L4-2.4L SOHC (2005)
Q: Is ETACS-ECU connector C-226 in good condition?
YES: Go to Step 2.
NO: Repair or replace the damaged component(s). Refer to Harness Connector Inspection. If the functions or equipment, which are described in
"CIRCUIT OPERATION", work normally, the interior light loaded signal should be normal.
STEP 2. Check the battery 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. Measure the voltage between terminal 20 and ground.
-
The voltage should equal approximately 12 volts (battery positive voltage).
Q: Is the measured voltage approximately 12 volts (battery positive voltage)?
YES: Go to Step 4.
NO: Go to Step 3.
