Thanks for choosing Just Answer . I'm Wolfgang here to help!!Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail. Do not rate yet, just reply. Put yourself in my shoes, I can not see, smell, hear, feel or touch your car, nor do I know any history on it. So take into consideration I am doing my best based on what you tell me. Also understand fixing cars often requires sophisticated tools, that you may not own. So even if you can not do what is outlined in my answer, that does not mean my answer is wrong deserving to be rated negative.
first I do need your vin # ***** the vehicle and second do you have a volt meter to make checks?
Did you scan the module for codes?
ok checking on this just an update!! thanks
ok the pcm relay fault there is a rewire that needs to be done on that . but lets make sure by checking the powers at the relay (red wires) make sure you have 12 volts on both . that relay is located in the ecm box
please let me know!!
both codes come back after a clearing of the ecu?
ok i need you to perform a voltage drop check from pin 62 of the ecu to pin 1 of the J271 relay (86a circuit). and then voltage drop from pin 4 of J271 to pin 21 of the ecu (85 circuit) . this is need to be done with the relay in the socket and engine running and then engine cranking.
that will be fine!!
