Lancer L4-2.4L (4B12) (2009)
STEP 25. Check the wiring harness for line-to-line short. Measure the resistance at ETACS-ECU connector C-301
CAUTION: Disconnect the negative battery terminal.
1. Disconnect ETACS-ECU connector C-301, and check that there is continuity at the harness side of ETACS-ECU.
2. Check that there is continuity between ETACS-ECU connector terminals 6 and 7.
OK: No continuity
Q: Is the check result normal?
YES : Go to Step 37.
NO : Go to Step 26.
STEP 26. Check the wiring harness between joint connector (CAN1) C-06 and combination meter connector C-04 for line-to-line short.
Measure the resistance at joint connector (CAN1) C-06.
1. Disconnect joint connector (CAN1), and check that there is continuity at the harness side of joint connector (CAN1).
2. Check that there is continuity between joint connector (CAN1) terminals 3 and 14.
OK: No continuity
Q: Is the check result normal?
YES (vehicles with KOS) : Go to Step 27.
YES (vehicles with WCM) : Go to Step 28.
NO (vehicles with KOS or WCM) : Go to Step 48.
STEP 27. Check the wiring harness between joint connector (CAN1) C-06 and KOS-ECU connector C-31 line-to-line short. Measure the
resistance at joint connector (CAN1) C-06.
1. Disconnect joint connector (CAN1), and check that there continuity at the harness side of joint connector (CAN1).
