It all started with an ABS issue - drove it from Orlando to Miami with a bad ABS due to i was far from home and it be 3 AM.

Once i was home i took out the ABS relays and this is where my life went to hell.

the Relays caused a drain - killed my 12v - no biggie i can recharge and find the drain.
a week went on and the Hybrid battery got a malfunction too AWESOME!

finally replaced the ABS and tried starting it up - car stalled. immediately. - This is the BIG issue!!


codes said it was the ECU - which was caused by the drain i assume

c1259 and C1310- toyota gave me a diag and it pointed to the "Power Management ECU"

SO. i fixed the ABS - Fixed the Drain - Fixed the Hybrid Battery - Replaced the ECU ( not the SKID ECU )
and the car STILL does not want to stay on!

THIS is what the Toyota mechanic gave to me : https://imgur.com/a/4vhfA
These are the codes AFTER the everything was done : https://imgur.com/a/N5AbV ( same thing)


my next idea is to check to replace the SKID ECU

i know im asking for a miracle - car has been sitting there since AUGUST - im afraid if i take it to the dealer they will just backtrack on the ECU and not be the issue.

 

Just guessing.

The skid control and ECU seemed to be linked. Removing the relays may have caused a lack of communication with the HV control ECU. Did you turn on the ign with the relays removed? If so, these codes could then be triggered.

Other issues:
Are the HV battery cables connected OK?
Is the HV battery taking a charge?
Is the 12 volt battery OK?
Any blown fuses?

If the car has been sitting a time the HV battery may dead.

 

i actually had a toyota mechanic come and check it out.

a fuse. the hybrid battery fan fuse was out. it would stop the car from turning on

 

Thanks for posting back with the fix!

These systems are interconnected. A problem in one area can cause another area to set a code not related.

It is NOT easy to run down the problem.
