2017 Infiniti Q60 Intermittent No Start Diag & Fix

In this video I show the process that it took to fix the intermittent no start condition. It would log multiple codes in different modules and could have easily made the wrong call a few times. But sticking to a diagnostic process I was able to pinpoint the issue.
Some of the misleading codes:
In the ECM: P062F Which relates to internal EEPROM error and service info describe possible bad computer (ecm)
In the BCM: B26F4 for starter control relay
B2562 for low voltage
both of those can point out to possible faulty bcm itself or ipdm
In the IPDM: B2098 Ignition relay on circuit
B210C Starter motor control relay off circuit
B210E Starter motor relay off circuit
Those 3 codes could point to the ipdm itself or bcm

This could have been a multiple module parts canon situation, I wanted to post the codes here that I forgot to put in the video that could lead you to make those calls.

We are in the same job and i learned from you a lot.
after you spent many hours to diagnose this problem some one need to pay you for all your time how can you explained this for the owner?
Some owners can tell "but is just a fuse" this is one of the big problems in our diagnosis job how you deal with that?

[@humbertocorado5750]

Wow just for one fuse can cause all those problems but you didn't give up find the cause of the problem you are really good in this field good technician good blessed you sadel

Thank you for watching

Thank you for all the diagnoses, it's crazy what some people will do to their expensive cars. AS FOR ME, I do not trust a floating voltage or ghost voltage, or voltage fluctuation on a scope or multimeter as these devices are high-impedance tools and do not load the circuit or do not pull amperage enough to load a circuit. When I see these funky voltages, I then touch my normal test light to the line and if the voltage drops down near ground, I know the circuit in question cannot carry a load to light a normal test light as seen as a loss of voltage on the meter or scope. Now I can trace a weak contact, splice, fuse box problem, corroded fuse terminal??
In this case, I would have backfeed 12V one junction at a time towards the fuse box until I found the VD. In the end, as it always is, finding the actual problem as the very last step, an improper type fuse inserted into the fuse box, OMG

Painful, I've telling my techs for 40 years now when you see a relay always to straight to it, all the relevant circuits are right there. It will always provide guidance on what direction to go.

Great tip!

I think the green 30amp fuse would have worked good if they have used a fuse holder and if they have crimped two female spade connectors. Always enjoy your diags ,but its somehow a long video for this simple problem. No offense i love this channel ,but you maybe will get more views if the videos dont exceed 30-35min. Have a good day man 😊

[@DTEAuto]

I definitely understand, it's always hard to decide on putting out content that is long like this situation. I still wanted to present it to anyone that would have interest, the fact of the matter is that I tried to condense it down in the matter and steps I took the best way I could. This was a 10-hour process that I cut down to an hour. Thanks for the input and hope to keep your views as best as I can.

Nice job

[@GraditelMacedonia]

Bravo.

[@markferraro5250]

Phenomenal video SADEL. make a load pro with 1156 bulb im parallel with you double stacked scope or dvom test leads

[@DTEAuto]

good point and thank you for watching

[@aksgarage3230]

Check out the qx56 I'm working on ak's garage. I'm trying to figure it out.

[@weldingjunkie]

Hey brother do you know what video you made of the in cylinder capture with the spark that was blatantly off and was moved over from TDC? I can’t find it for life of me

[@DTEAuto]

Hey, do you have a little more detail that you might remember which could help me try to narrow it down?

[@weldingjunkie]

@@DTEAuto I think it was a bmw, it was a phenomenal show of quick glance that the timing was off. I watched many of your videos I can’t remember which one it might of been older. I’m pretty positive it was a bmw you had 2 in the shop at same time I think

[@DTEAuto]

I'll have to try to go through the videos and see if I can find it also

[@micku9954]

wow that was crazy ..

[@djosbun]

Wow…….makes you shake your head on why in the hell someone would purposely put that incorrect fuse in there.

[@DTEAuto]

Definitely very frustrating for sure

[@IamReadyToRock]

Quién puso eso ahííí? 😅😅😅

[@DTEAuto]

🤷‍♂️
