little help. pcs and abs message flashing .........

whats up everyone, hoping to get some help , 21 limited . smelled some burning wires . noticed this happened.

1. PCS AND ABS flashing to call dealership.
2. rear brake lights ,running lights and turn signals not working
3. hazard lights worked .

went to dealership they said diode was bad because i installed the plug and play rear pillar lights without a relay. okay no problem.

hear is a pic (burnt diode) can anyone help with a part number or wear to get this ?

driver side front kick panel is location of these pics.

i checked the the fuses under the hood and under the driver side dash. the pillar lights i unplugged checked all the wires and lights with this system and they still work the only damage i seen was this diode.

when picked this up at dealer the manager said it was not covered under warrenty and that he was told not to work on my runner any longer... unless i wanted to pay 10,000 plus they wanted for the fix . ( assuming they were going to replace the whole wire harnes this belongs to. )

thank you for any help
