What are the symptoms of a faulty LCM?

Several indicators may suggest a malfunctioning Light Control Module (LCM) in your vehicle:

  1. Intermittent or non-functioning lights: Lights controlled by the LCM, such as headlights, taillights, or interior lights, may work inconsistently or not at all.

  2. Flickering lights: If your lights flicker unexpectedly while driving, it could be a sign of LCM trouble.

  3. Lights staying on: Even when the vehicle is turned off, lights may remain illuminated due to LCM issues, draining the battery.

  4. Failure of multiple lights: If several lights fail simultaneously, it could indicate a problem with the LCM rather than individual bulbs or wiring.

  5. Dimming or unusually bright lights: Inconsistent brightness levels of lights controlled by the LCM may signal a malfunction.

If you notice any of these symptoms, it's advisable to have your vehicle inspected by a qualified mechanic to diagnose and address the issue promptly.
