Lancer L4-2.4L SOHC (2005)
1. Remove the combination meter.
2. Remove the seat belt warning light bulb. Then measure the resistance value between the bulb terminals.
3. Install the bulb to the combination meter, and then measure the resistance value between connector C-01 (terminal 9) and connector C-02 (terminal
35). The measured resistance value should be roughly the same as the value measured in Step (2).
Q: Are these two resistance values extremely different?
YES: Repair or replace the combination meter (printed circuit board). Verify that the seat belt warning light illuminates normally.
NO (much the same) : Go to Step 8.
STEP 8. Check combination meter connector C-01 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
Q: Is combination meter connector C-01 in good condition?
YES: Go to Step 9.
NO: Repair or replace the damaged component(s). Refer to Harness Connector Inspection. Verify that the seat belt warning light illuminates normally.
STEP 9. Check the ignition switch (IG1) circuit to the combination meter. Measure the voltage at combination meter connector C-01.
