Hi everyone, i got problem with my vehicle, just yesterday everything was fine my 2016 Lexus ES300H was driving without any problems next day when i tried to start my vehicle it's started normal after i switched to Drive i got message on dashboard-- , Vehicle does not drive forward on dashboard not showing ''D'' but Transmission is in Drive position, Reverse working properly Vehicle going rear and on the dashboard showing ''R'' also Neutral position working properly and on the dashboard showing "N", I towed Vehicle to mechanic diagnostics showing code P0705, mechanic replaced neutral transmission safety switch but problem not gone, he checked for a cut and short circuit on the wires now he asking to change Hybrid Vehicle Control Module and he not guarantee that the problem will be solve, maybe someone has the same problem and know how to solve please let me know thanks.

 

There must be additional codes set, did the mechanic tell you what they are? What is "Hybrid Vehicle Control Module" that is a generic name. We need more information to know what is going on.

 

thanks for the quick answer LeX2K but there is no other error code only shows P0705, Hybrid Vehicle Control Module located under driver side it’s computer unit for Hybrid, how mechanic explaining there is signal going to the Hybrid Control module from neutral transmission safety switch (sensor) but there is no output signal to the transmission computer and because not recognize D position on the transmission

 

89981-33150 does not appear to be a Toyota or Lexus part number. Google shows 4 total results. What's up with that?

 

oh it's another problem this module on the picture is my Vehicle Hybrid Vehicle Control Unit, but today i was in Lexes dealership in Brooklyn New York they also can't find this part number in the system with vin number it's shows 89980-33030 i don't know what is wrong with this module, only part what i find with a similar number was on Ebay 2017-2018 LEXUS ES300H HYBRID VEHICLE CONTROL MODULE 89981-33170

 

89981-33170 does not show as a Lexus part number, 89980-33030 does come up as a Lexus part number called COMPUTER ASSY, HYBRID VEHICLE CONTROL. Such a module is not likely to fail it's possible the neutral safety switch is not adjusted properly.

Failing that don't know what else to offer.

 

If the mechanic checked correctly the wiring for short or cut, replaced the shift lever sensor then he should check voltage coming out from specific pins from the hybrid control module with ignition on per manual. I assume he did that and the hybrid control module needs to be replaced.

The shift lever switch was probably fine and it did not need replacement. Unfortunately this is how mechanics work. They start changing parts hoping they will fix it. Then they claim more than one parts broke at the same time. What are the chances though?

You can try to repair the hybrid control module for $100.

So which code is it? They have different troubleshooting process. So you're not replacing for the sake for replacing. Have you spilled water or drink into the shift lever? 2016+ models come with a boot shifter so its not an issue.

P0705 757 Logical inconsistency in shift sensor output values

• Wire harness or connector
  
• Shift lever position sensor
  
• Hybrid vehicle control ECU assembly

Hi,
My vehicle also has the same issue. Did you happen to fix your car?

 

I have the same issue coming on my dashboard but it was fine an hour ago I was working on fuse fuses in my hood and underneath the - because my GPS and radio - screen is out so I'm trying of fixed that and then I must have touch the fuse that created this issue does anyone have any answers for that? I definitely caused the problem because it like I said I was working on fuse Box checking for fuses to fix my GPS radio - screen and cause this issue now

 

Did you find the fix to this problem?
