U-Codes - Dealer Invoice - Any Ideas?

[harv1000]

Hi All,

Just got my 300C back from the dealer. They were checking for a slipping tranny. Replaced a connector and topped up fluid. They mention doing a starscan and getting the following codes: U1408, U140A, U1409. Says they are stored as DTC's. Does anyone know what these mean? I'm just curious as the dealer (service rep) couldn't tell me.

Thanks.

U1408 - Implausible Brake Signal Received

U140A - Implausible Right Front Wheel Speed Signal Received

U1409 - Implausible Left Front Wheel Speed Signal Received

Don't know what this means, but these are the descriptions of those codes.

Just digging into the service manual, those codes are definately NAG1 transmission related and from what I gather were most likely a TCM problem.
