Hi guys, I have a weird problem with my low beam. they doesn't work but my high beam do. I've already check both of fuses for low beam and everything is fine. To be honest,they we're working fine before I tried LED light bulbs. After that I've lost my low beam

ACURA TSX 2009 2.4l


thank you for any kind of help!

 

You have LED low beams..? :

 

I bought those :

 

I've put back my halogen bulbs if it what you asked.

 

Hum - Halogen low beams? Do you have one of the Canada-only "super-base" models without the shark fin antenna? I think it's the only model that has halogens, all others have HIDs.

 

TSX's had HID standard I thought.

 

nope, TSXV6Guy is right. the lowest model in Canada (up until MY11 or MY12.. not sure) did not come with HIDs.

 

and judging by his S/N he's probably from Montreal area or something If OP's could provide more information like where they're located, we could stop acting like internet 's and more easily help them

 

I'm from montréal guy! sorry for the delay I was working. SO! Today I bought two more hallogen bulbs. Low beam still doesn't work..

 

Did you check the fuses with your eyes or with a volt meter? Many fuse failures are missed checking them by eye.

 

With a voltmeter,

 

This is probably a dumb question but do my headlight for the HighBeam are the same for the low beam? Go the car a few day's ago.

 

There are separate bulbs for the low and high beam. My bet is that something wrong with one or both of the MICU (Multiplex Integrated Control System) - See description further below.

Start by checking the No. 1 (10 A) fuse in the passenger’s under-dash fuse/relay box.

Otherwise you need to get a hold of the service manual (send me a PM for more details), but you may want to have the dealer diagnose this, as it involves a complex set of tests etc.

System Description Headlights System Description

The headlight system is composed of the driver’s MICU, the passenger’s MICU, the headlight and dimmer/flash-to- pass switches (inside the combination light switch), the left and right headlights, and the high beam indicator. Each MICU controls each side of the front parking/side marker light and headlights. The taillights and license plate lights are controlled by the driver’s MICU only.

Low Beams

When you move the headlight switch to the ON position and the dimmer/flash-to-pass switch to the low position, a ground signal is supplied to the No. 8 terminal of the driver’s under-dash fuse/relay box connector R (24P). The driver’s MICU then energizes the low beam control circuit, supplying battery voltage to the low beam of the left headlight, turning it on. Also the driver’s MICU sends the message to the passenger’s MICU by B-CAN communication lines. The passenger’s MICU then energizes the low beam control circuit, supplying battery voltage to the low beam of the right headlight, turning it on.

NOTE: If there is a B-CAN communication failure, the headlight back-up circuit commands the right low beam to come on when the ignition is on and the headlight switch is in the headright position. The right high beam does not come on if there is a B-CAN system failure.

High Beams

When you turn the headlight switch to the ON position and the dimmer/flash-to-pass switch to the high position, ground signals are supplied to the No. 8 and No. 22 terminals of the driver’s under-dash fuse/relay box (driver’s MICU) connector R (24P). The driver’s and passenger’s MICUs then energize the each side of the high beam headlight control circuits, supplying battery voltage to the high beam headlights, turning them on.

 

HIGHBEAMS are also your DAY TIME running lights.
LOW BEAM-are the headlights that you turn on at night.

our American TSX run 9005 as HIGH BEAMS..your link is showing 9005 bulbs and looks like you are trying to run them as LOW beam?

I don't know what bulbs are your low beams over there on your part of the country. BUT ours are HID D2S, I am assuming your low beam might be a 9006 like the Honda Accords.
