Frequently Asked Questions

Can a software update fix P2810?

Often yes. Module software updates can correct data output formatting and communication timing issues between the TCM and other modules.

What happens when stability control gets wrong gear data?

Incorrect gear data can cause the stability system to over or under-react to wheel slip, since its calculations depend on knowing the current gear ratio.

Is data corruption on the CAN bus common?

Intermittent data corruption can occur from wiring damage, loose connections, or electromagnetic interference near CAN bus wiring.
