05 rl with 175k

drove car to a friends house no lights on dash after sitting for the day while we were at work came back and started my car
the car started fine but kicked on all the lights


check emissions
vsa
the triangle. /!\
sh-awd

hooked up scanner and had the following

p0385
83-1

clear codes and they come back as soon as the car starts

swapped out the crank sensor (did timing belt and water pump while in there) still have the problem lights

i have driven the car over 200 miles and still drives fine with the lights on

only thing i have noticed is making a low speed turn and coasting the chugs/bucks a little bit once i get back on the throttle to continue driving it’s fine
this happened 2 times in one day

what else can i test and look for please help

 

It's not the battery?

 

I wouldn’t think so i have no issues starting the car

 

DTC 83 is "No VSP signal", Looks that VSP is vehicle speed signal. Going through the SM to see what it means. You have a TPMS light on?

 

yes the tpms does come on after driving for 2-3 min
this has been like this for years i thought this was for tire pressure?

 

Does the HUD say system ok?

 

Yes it is, but the TPMS unit has communication with the PCM. That is what code 83 is. Your gauges and navi normal?

 

yeah Navi and gauges all work as should

what do you mean by does the HUD say everything ok?

 

On the LCD in the gauge. There should be a TPMS section. In the section it should say "Tire Pressures OK/Abnormal" and something like "Systems Normal". You might have to press the trip button on that screen to get it.

 

I think the 2 codes are unrelated. There might be a wiring issue by the TPMS computer. Same might be true of the P0385.

 

last time i cycled thru that i remember it just showing the 4 wheels and the psi of each wheel
in orange it shows check tpms

 

OK though without a lot of posts on this forum yet, you may not be aware that a sketchy battery, (yes, they occur often on these cars.....while still cranking the car just fine) can give you a load of false warnings and odd indications. You may want to have it checked out. Just sayin'....

 

i will look into this

 

Well, send a pic, but I'm gonna say that it is 83. If this has been going on for years, then 83 won't be solved by a battery.

 

Thanks guys I’ll be able to get back to the car tomorrow and look into these things

 

this is what i got

 

Huh. She driven till the light came on or is it a cold start?

 

Also the AFS light may be part of the cause of the VSA light. I think it relies on the level sensor for inputs. Here is a link for the level sensor.

 

this is a cold start
I’ve swapped that sensor before and it does not fix anything
light has been flashing for years
when i start the car at night you see it move and adjust but doesn’t do anything while driving
light always flashing

 

Quick update
went and had the battery checked out gentleman at AutoZone, hooked it up to the tester. It tested fine. We stood there. Spoke for a minute then he decided to hook the tester back up to check something else to see if the alternator and starter were working properly ……. the battery failed the test. The second time he hooked the terminals to it. They swapped out the battery, so I have a new battery now lights are still on.

 

Idk if anyone is paying attention to this thread but……


update::::::

took it to a local Honda/acura shop

gave them the run down of what i have done and replaced

shop comes back to be with….
So we ran the codes and see you have multiple lights on
we recommend to replace crank sensor ( which i already explained i did that )

they insisted that i need to use Honda oem parts so they need to start with replacing that @ $888.63 for the part and labor

i ask if they do this and find nothing will i have to pay for the part

short answer is yes i get stuck with the bill

in at a loss for words here and tell them go for it cause i need to have this fixed

fast forward couple days later

sir we replaced the part and same issue ( well no duhhh i told you i did this already)

we would like for you to come down so we can show you what we found….

well I’m at work and it would be too late for me to get there before you close
ok well we found a bunch of wires chewed up
we will send pictures
quote for harness over $7000

well looks like I’m going to be doing some soldering and eBay shopping

 

OOF. That'll cause a few issues. Very unusual damage. They look melted. I think someone jumped it backwards. Well good luck in both finding all the matching color wires and all the solder you are going to use.

 

crazy right who knows how long it’s been like that
Thanks for the luck 😂 I’ll keep it posted what’s going on

 

Hehehe. Get ready for some pain.

 

I have a 05 RL myself and it is throwing all system lights as well. So you found out it was the wiring harness? I’ve been trying to figure out what is wrong because I just bought mine a week and a half ago and on the way home with it all system lights came on 🤦🏼‍♀️ but also my navigation screen is out. But it is back light so idk. Feel like I got completely screwed over on this car.

 

What lights? .

 

VSA
SH-AWD
TP
ABS
Air bag system
but no check engine lights
it’s all safety lights

 

I'd clear the codes first and then see which ones return. Also check the battery. It will do weird shite like that when its almost ded.

 

I started having problems starting on Sunday and yesterday. But it would start just fine if we moved the battery cables a little so we went and got post caps and put on it but still doing it. So yeah I’m going to go have the battery checked today. I was going to just sale the car and find something else.

 

I'd replace the cable and then clear the codes. It should not move at all when tightened. Don't jerry rig a cable. Get OEM if you can. Also, to clear the codes you need a scan tool through the OBD II port. Disconnecting the battery won't erase some codes.

 

Wowsers @Buddha823 ! It looks like bite marks ... like a rat got in there and just chewed some random things !!!

 

You might have some animals chewing on your cables...mice, squirrels, etc.
