Volvo m4.4 wont enter bootmode

Post by Dedspool »

I applied 14.5v to oin b8 of a 98 s70 NA ecu. Part munbers are the 607 243 ? The wiki says it works for this. The oem ecu took a dive.

Does this mean ecu is bad or i need 15v or so? I read different things but im pretty sure this is my issue. It goes to erase and cant. :(

I have injectors and maf. Etc in so cant tell if the codes are normal stuff or what. (Harness is untouched and car fires up. I know stuff well enough to say.).

LOOKS LIKE BOOTMODE ISSUE. anyone have advice after all this. Idk what to do. I need ti flash it to drive.
