warning lights on dash. ECU fault? help.....

**virgoz** · 27-02-2014 11:58 AM

Hi guys,

sorry, noob here.

My wife has an '05 Euro Luxury. when driving now, the dash warning lights (ABS, Brake, VSA, etc) come up and stay on. Sometimes only after 10 min of driving, but the car still continues to handle normally. Then the Engine warning light comes on and the car starts running bad and "surging" when stopped at the lights and idling.
Any ideas?
Is the ECU knackered? (where on earth is it???) . Got a Honda mechanic telling me he can replace it for $3000. That scares the hell out of me.
thx
Tim

Don't take it to Honda
Go see Josh @ Sleeping performance
He owns a garage south east of melbourne and can help you with your car

Jesus Christ. Yeah I've heard good things about Josh @ Sleeping Performance. He is a user on here as well - 'stndrd' or something is his name.

I will find out this afternoon when I see my mechanic. I need to find out where it is anyway as well because I'm getting it reflashed next week.

thx man! may be exactly what i need...

Most likely behind/under the glove box

The ECU is located under the centre console compartment area.

Access is via the plastic panel in sides of footwell.

Here's a guide:

Just a note that's the American TSX so the ECU placement is flipped
Meaning the plugs "side" of our ECU is on the passenger side footwell etc.

dont thing thats an ECU/Engine problem..... cause if it is you should be getting the CEL not the ABS/brake lights

do a code read, probably the braking system has issue somewhere

generally with hondas, make sure you get the HDS codes. not normal obd2 P0xx codes (they dont tell you much). then HDS code in relation to the make n model of the car will tell you the problems same models have had issues with in the past.

^^^As above.Sounds like it's the accelerator pedal position sensor.A short term fix is to disconnect the positive terminal on the battery for 5-10 mins then reconnect.
