Lancer L4-2.4L SOHC (2005)
1. Remove the combination meter.
2. Remove the high-beam indicator 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 terminals 4 and 5. 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 headlight-beam indicator light illuminates normally
NO (roughly the same) : Go to Step 7
STEP 7. Check the battery power supply circuit to the combination meter. Measure the voltage at combination meter connector C-01.
1. Disconnect combination meter connector C-01 and measure the voltage available at the wiring component side of the connector.
2. Measure the voltage between terminal 4 and ground.
