Code P3000

Hi Bruce,

I suggest that you download the relevant repair manual pages from techinfo.toyota.com or else the equivalent toyota-europe site, for detailed troubleshooting advice.

DTC P3000 is logged by the hybrid vehicle ECU. If the battery ECU did not log any codes, this would provide evidence that there might be a communication problem between the hybrid vehicle ECU and the battery ECU.

Following is a list of INF subcodes associated with DTC P3000 (per the Ecrostech miniscanner user manual):

P3000 - HV Battery Malfunction​

123 ​

​

Input of abnormal signal from battery ECU (HV Battery System Malfunction)​

124 ​

​

Input of abnormal signal from battery ECU (high voltage fuse blown out)​

388 ​

​

Discharge Inhibition Control Malfunction. When charged battery is low due to
leaving the vehicle in N position, gas shortage or HV system malfunction​

389 ​

​

Drop of high voltage. When main battery is dead or main battery is dead due to HV system malfunction​

 

Hi Bruce,

See p. 4-12 of the following document; however it is not too helpful: http://www.autoshop101.com/forms/Hybrid14.pdf

Here's the Toyota Europe website; their pricing is in Euros. Perhaps this site will allow you to subscribe:
Toyota Service Information

The three-digit subcodes mentioned in my prior msg are visible only to the Toyota proprietary diagnostic laptop or handheld tester.

I no longer have my 2001 repair manual. This problem is thorny, so if you are not able to access the Toyota repair manual info it probably will be necessary to rely upon the Prius specialist at your dealer.

Good luck.

 

Hi Bruce,
I realize this is an old thread and you may no longer be here but this is the only place on the internet I've been able to find an exact description of what's happening to my 2006 prius. I'm just curious,what ended up being the issue? Was it the hybrid battery or something else?

 

Does techstream via mini vci show the subcodes to your knowledge or is it still toyota dealer only info?

 

tech stream is what the dealer uses, and is fine on mini vci.

 

any updates one the outcome of this? i just got this on my 2008 and after using dr.prius app i can see that block one of my voltage is enough below the others to trigger some malfunction... going to switch out that block and let y'all know...

 

Hi Priusvid,

I am getting the P3000 set as an historical code on my 2007. What did you do to correct the low block? Did you have the battery recalibrated? When you said "switch out the block", did you mean swapping out the cells in the battery itself?

Thanks.

 

ok .. checked other system called " HV BAT " ... getting P0a80 'replace hybrid bat. pack'

block voltages all seem to be 16- 16.3 with the exception of
1 at 15
4 at 14.98
8 at 15.98 ( not really a concern)

.: blocks 1 and 4 are an issue being 1v lower than the rest .. i beleive its 1.5 dif. between blocks that trips the unhappy triangle ..
