please help ecm

engine light came on ,brought it to a shop and he checked code ,it said replace the ecm,just wondering if this would be right or something else causing it to say this??? i read threads saying that its strange for these ecm to just go ???? after he scanned it engine light went off??? and if i keep driving it will i have more problems with the truck\???? thanks for your input guys.....

 

what was the code?..what truck and engine?

 

not sure ,he checked scan reader and told me ecm needed to be replaced and to call toyota and check for warranty,did and not covered.....and its on back order and would take a few weeks to get one in

 

its a 2006 v6 tacoma

i just purchased an obd2 reader ,hooked it to the truck ,no codes come up and truck will just click??? im stumped????

 

double checked connections ,tested battery ,all good , think its starter??? i put on new alternator few months ago ,and when it starts it holds charge....

 

If it were my truck, I wait until a new code is produced and seek a second opinion before replacing an expensive ECU. It could be something as simple as a voltage spike or a loose connector. If the existing lug does not fit the battery post, I would replace it as soon as possible with one that does. If the cable is damaged or undersized, then I would replace it as well. The battery is a voltage stabilizer and filter for the power produced by the charging system.

 

the code finally came up p0606, it said replace ecm ,this will be the 3rd one since new.....

 

Are you still driving? I'd go till it went completely out. Seems like truck needs a carburetor, since it keeps burning ECM!

 

sometimes it starts ,sometimes it wont ,toyota said the ecm i need is on back order and it will take 4 to 5 weeks to get it ,so im putting in a used one ,hopefully have it in by thursday .....

 

I would have went used as well. I wonder why it keeps killing the ECM?

 

Hi,
Are you saying that the ECM has been replaced twice or that this is the third time the code has come up?

If the ECM has already been replaced twice then there is something else causing this to happen. The ECM is pretty much bullet proof. Maybe someone else with more knowledge will hop into the conversation. Urban myth true or not was that jump starting was not good for ECM.

Something has to be wrong?

 

this is the 3rd ecm that has been put in this truck since 2006 ,but this time warranty is out and with a 4 to 5 week wait ,im getting a used one !!!!!

 

This seems to be an ongoing problem, one definition of insanity is doing the same thing over and over and expecting different results. Its not the ecm!

If this is the third ecm, two of them covered under warranty then I'd be asking Toyota to replace this one under warranty also or give me a reason why its your fault that they are failing! Something is wrong with the vehicle to cause this to happen. US has a lemon law and I think this would definitely fit the criteria, a major problem that they can't fix after multiple attempts. If the dealer won't help call directly to Toyota Canada.
