Please I need help. I was doing diy with my car this morning and I fried some things up.
The car was very ok. One of the three wire of
the coil 2 was naked so I use black tape to tape it up.
Hmmm I was curious to no the voltage on each of the three wire. I try use my multimeter but discover the battery was dead.
so I decide to use test lamp. I put one end of lamp wire to the ground and the other to number 1 coil wire, no voltage. I reverse it this time one to positive on the battery why the other end to the coil wire the test light light up. I was still curious because I want to no the signal wire among the three wire. I did this test in 1 and 2 plugs.
Before I no ,the car started misfiring .
I new the coil was not firing again so swap coil 1 and 2 to coil 3 and 4, the coil was working fine but 1 and 2 was not firing.. i off the car remove battery head same problem went online to see how to reset ecu, which I try same wahala.
Off the car jejely enter house go sleep.
Wahala don come .
Though I regret my action but I am the kind of guy that like doing things my self.
I scan for code which give me
P0603.
I my going to replace the ecu ?
If so will I program it ?
How much is the ecu..



Make I off my phone cry small
Lol.

Sort out the ignition coils and clear the code. With some luck, your ECU should relearn.

Check cylinder 1 & 2 coil wiring

Try checking your wire harnesses to the coil... Just might be it. Maybe not properly tighten

If the coil driver (IC)in the ecu is damaged ,u either locate and change the driver or Change the ecu, to Change the ecu ,just get a scan tool and reprogram the key once that is done the new ecu will be coded in. Best of luck, I love DIY, I learnt everything I know that way, but I don't try anything I have not learnt online from other people experience

[color=#006600][/color] thank you
Have actually open the ecu and trace the coil line . The only thing I see that might be bad is the resistor.
I show it to tv repairer but he said the resistor can't be removed because it is imprinted resistor. I don't no how through this is

What usually goes bad are ics, send pictures of the board

[color=#000099][/color]ok I send the picture tomorrow
