Hello everyone,
I have an issue with this module. Module came in from someone else trying to clear the crash data. Client says originally module just had crash data in it when scanned. When I received it from someone else trying to reset the module and hooked it up diag it already had B1163 B1164 B1165 Airbag Malfunction which is internal failure. I try flashing with AST Can and same errors appear. I then try with CPT and loaded files another post There is no communication after writing the crash. - CarProTool .
Originally when I receive the module it was reading 89170-12J10 and not 89170-12J00 like on the sticker of the module. I don't know if this is because someone flashed it with the incorrect firmware. I try with other files from DK and also still B1163. I wrote c flash with 89170-12J0 and now shows correct part number with diag.
I do believe that initially the module did not have airbag malfunction but now after someone else has tampered with it now it does. I have spent countless hours on this and I'm only doing this to just try to figure out if it's fixable after having B1163 internal. I see other users have also encountered this internal failure in toyota modules after write.
I have written c flash and d flash and did not help. I read also that this module perhaps has 95M01 memory. Maybe stores B1163 there and cannot be cleared?
Does someone have a working set of files to try that is tested? C and D Flash and possibly 95M01?
Attached are original reads from the computer and pics of the module
Thank you
