Lancer L4-2.4L SOHC (2005)
Q: Is ETACS-ECU connector C-226 and C-228 in good condition?
YES: Go to Step 4.
NO: Repair or replace the damaged component(s). Refer to Harness Connector Inspection. The system should communicate with the SWS monitor
normally.
STEP 4. Check the ground circuit to the ETACS-ECU. Measure the resistance at ETACS-ECU connectors C-226.
1. Disconnect ETACS-ECU connector C-226 and measure the resistance available at the junction block side of the connector.
2. Measure the resistance value between terminal 3 and ground.
-
The resistance should equal 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
YES: Go to Step 6.
NO: Go to Step 5.
