Hello and welcome. My name is ***** ***** you for visiting the site, I am reviewing your question and will reply shortly, thanks.
Thank you but you have to accept the offer.
have you changed the relay?
thats the first step
GENERAL DESCRIPTION The HIVEC Automatic Transmission supplies the power to the solenoid valves by way of a control relay. When the TCM sets the relay to ON, the relay operates and the battery power is supplied to all the solenoid valves. When the TCM sets the relay to OFF, all solenoid valve power is shut off and the transmission is held in the 3rd gear position. (Fail Safe Mode)DTC DESCRIPTION The TCM checks the A/T control relay signal by monitoring the control signal. If, after the ignition key is turned on, an unexpected voltage value, which is quite a bit lower than battery voltage is detected, the TCM sets this code.
change the at control relay................... thats the answer
so it does not run? why would you not say that from the start?
so why tell me after the fact....you tell half the story and expect the correct answer.... does it have spark ? compression? injector pulse? fuel pressure?
so if it has all of the above it will run....
how many psi of fuel pressure? and what is the compression?
well you answered yes ...these are the questions i need answers to ...in order to solve your issue...
Hello and welcome to JustAnswer!
Do you still need help?
Have you checked for spark?What were the fuel pressure and compression readings?
What fault codes are setting in the engine controller?
If it doesn't have spark there is little chance that no fault codes are setting. Give the starter a solid ten seconds of cranking without letting up and then check for codes again.
Let me know what you find and we can go from there.
It's an actual scan tool?
What is the brand and model of what you're using?
But is it a generic OBDII code reader or an actual scan tool? A scan tool is a multi thousand dollar tool that will allow for the monitoring of data and perform actuator tests.
Do you have a compression gauge?
Have you checked fuses? If fuses are good and you don't see a visual wiring issue you're going to need testing equipment to be able to diagnose the problem.
Unless you'd like to start replacing likely parts you're going to need to need the ability to do testing to proceed.
Let me know if you need any more help.
