Toyota C-HR DRL Not Working? Replacement Guide (2021-2023)

Toyota C-HR DRL not working: what is actually inside

The 2021-2023 C-HR does not use a serviceable bulb for the daytime running light. The DRL output comes from LED boards mounted behind the headlight lens. The product photos in this guide show the boards and their connectors, including the left and right markings.

Does this match your symptom?

Toyota C-HR DRL not working

The DRL is out while the main beam still works. That pattern points at the DRL board or its supply, not at the headlight as a whole.

One side dim or patchy

Part of the board has stopped producing light. Compare the two sides before ordering: the boards are handed, so the left and right units are not interchangeable.

DRL flickers on bumps or after warm-up

Intermittent output before it fails completely is a board or connector symptom. Check the connector seating first, then test the board.

Confirm the part before you order

• Fitment: Toyota C-HR, model years 2021-2023.
• The boards are handed. Match the connector and the board shape to the unit you are replacing.
• If the lens is cracked or there is standing water in the housing, the board is not the whole repair: the housing needs to be dried and sealed as well.

What the repair involves

Reaching the boards normally means removing the headlight and opening the housing. The exact bumper and headlight removal sequence, the sealant specification and the curing time are model-specific, so follow the service manual rather than a generic sequence.

If you are not comfortable opening a headlight, a workshop can swap the board once you have the correct part.

FAQ

Q: Both C-HR daytime running lights are out. Is it a fuse or the boards? A: Check the fuse and the DRL supply first. A board failure normally takes one side down; both sides at once points at the shared supply, so rule that out before buying boards.

Q: There is condensation in the headlight. Will a new board fix it? A: A board is only part of the repair if water is getting in. Dry the housing, check the seal and the vent, and fix the leak before fitting a new board, otherwise the same moisture will damage the replacement.

Q: Can I replace only the failed side? A: Yes. The boards are handed, so order the side that failed. Match the part to the model year before ordering.

Standards

The daytime running lamp is governed by UN ECE Regulation 148 in most markets and by FMVSS 108 in the United States. These rules define when the lamp runs and at what output; a replacement board has to restore the output the vehicle was built to.
