Michael Dande says:

thanks for the video

now here is my story

i drive a 2007 Toyota Mark x its has the 4GR engine this Engine is similar OR almost Similar to the engine in Lexus is250,

many years ago i developed a minor problem with transmission Which seemed to clear away by itself

the car Would REV so high(4000RPM) and the rev will not match the speed it was engaging gears 1, 2, 3 but omitting 4 ,5,6

reported to mechanic .. all he did was disconnect the negative side of the battery terminal and reconnect it back then the car performed well with no problem

Many months later this problem came once in a while and i did resolve it by disconnecting the battery terminal

the problem became more and or routine service i asked the dealer to service my gear box by changing the ATF which was done and problem still persisted,

one day on routine battery service the technical told me my battery voltage is low(9.0)V There was no Check engine light , no Battery flashing all good) He Said "U NEED TO REPLACE YOUR ALTERNATOR SOON"look like the alternator is not charging well, he allowed me to drive

Few weeks later the Starter died and we had to replace it

after replacing the STARTER 2 months passed by and the second STARTER ALSO died

we replaced it with a new STARTER thereby after 3 months the ALTERNATOR "DIED/FAILED"

question

1 WAS THE POOR OR LOW VOLTAGE FROM THE ALTERNATOR CAUSING THE STARTERS TO DIE?

2. WAS THE LOW VOLTAGE ALSO CAUSING THE COMPUTER TO MALFUNCTION

we replaced THE ALTERNATOR and on that replacement we got a volt reading of 12.4V

now back to the Transmission

the problem became more common NOW I HAD to always reset the ECU by disconnecting the negative side of the battery every time i want to drive and when i switch off the car if i have to drive it i have to reset by the same procedure and this became annoying

on diagnostic no error code was captured

THEN gear box dealer decided we replace the shift solenoid which we did all 8 of them

same problem car shift 123 not 456 Very annoying

he then decided its an electrical problem

then we took to electrician he Scanned said error codep0176( shift body solenoid c remain open)

learning

p603 engine stall history

He said he cannot fix my car because

which

2 " am not sure if its the gear box or ECU OR WIRING" GAVE ME MORE HEADACHE

3.Imay be forced to strip off the car and that is too much of a job to do

I just got my surf registered. On the 25th I went to repco on a 35 degree day and went to start the car. Shattered idled and then shut off. Thought might be the primer pump as it the wrong size or switch as it was a old one. NOPE.

Check the ECU. Can see one of the capacitors has shorted out and leaked over a resistors. Bout to send it out to get repaired.

Before this happen I was wondering why I was getting crap fuel economy and such.

Great video Kelvin, I was wondering what type of shop would repair and ECU ?, here in Australia the mechanics don't know , and I really don't want to go to the toyota dealer

I've got a 2005 Toyota estima that slips and shudders in reverse if you stab the accelerator on a hill. But if you accelerate gently it doesn't slip. Could ecu do this? Trying to avoid an expensive pull down.

Hey Kelvin. Does this only apply to the UZs or all Toyota ecus? Very handy info you have shared with us all. Thank you
