2AB4 DME Code

[mcleansc]

Internal error: RAM checksum.

I recently used Protool to code out airbag faults after fitting an aftermarket hub and wheel. Code wasn't present before hand.

Went out to the car today to remove the airbag control module (d/c'd the battery to do this) and checked the codes after and this code had appeared.

Cleared the code, started the car and everything was fine.

Google hasnt really revealed much, I'm just wondering if Protool is the culprit or if it's just a massive coincidence? Anyone had the code before or know what it could mean?

Would give me an excuse to go Syvecs if it was bricked.......

In the Bentley Service Manual, it states DTC 2AB4 as Internal Control Module Checksum Fault in Non-Volatile Memory. Don't ask me what that means but that is what it states.

That's definitely technobabble only BMW technicians are trained in so us muggles can't read their manuals I've found a few posts of people having it but not what caused it. Ill take the car a drive on Saturday and see how it performs. I'm hoping it's linked to the battery, I've had it out a few times to charge and d/c'd it a few times to remove airbags.

Anything ever come of this? I'm having a similar issue.

No mate sorry. I deleted the code and it hasn't come back.

Have you been playing about with your battery of late at all?

Nope, and I realized this likely has no association with my issue. I appreciate your response though my man.
