Lancer LS L4-2.0L SOHC (2002)
YES: Go to Step 6.
NO: Repair or replace the connector. 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 6. Check the wiring harness between ETACS-ECU connector C-226 and the ignition switch (IG1).
NOTE: Also check junction block connector C-211. If junction block connector C-211 is damaged, repair or replace the connector as described in
Harness Connector Inspection.
Q: Is the wiring harness between ETACS-ECU connector C-226 and the ignition switch (IG1) in good condition?
YES: No action to be taken.
NO: Repair the wiring harness. If the functions or equipment, which are described in "CIRCUIT OPERATION", work normally, the multi-purpose
fuse number 17 loaded signal should be normal.
STEP 7. Measure at ETACS-ECU connector C-226 in order to check the ignition switch (ACC) line of the power supply to the ETACS-ECU.
1. Disconnect ETACS-ECU connector C-226, and measure at the junction block side.
2. Turn the ignition switch to the "ACC" position.
3. Measure the voltage between terminal 4 and ground.
-
The measured value should be approximately 12 volts (battery positive voltage).
Q: Does the measured voltage correspond with this range?
YES: Replace the ETACS-ECU. If the functions or equipment, which are described in "CIRCUIT OPERATION", work normally, the
multi-purpose fuse number 17 loaded signal should be normal.
