Why has the transmission light come on in my 2012 Mazda BT-50?

Asked by Michael

I have a Mazda BT-50 2012 manual and the transmission light came on, what would cause it to come on?

I’ve had a flick through the BT-50 owner’s manual (and I suggest you do the same) and all I can find relating to a transmission warning light is a single 'powertrain warning lamp' which suggests something is not right somewhere along the length of the powertrain. Sometimes this light will come on in conjunction with the 'check-engine' light and it indicates that either a sensor has failed or there’s an actual problem with the hardware. Beyond that, the light doesn’t offer any suggestions on what might be wrong, but bear in mind that the four-wheel-drive system in this vehicle is electronically operated, so there’s lot of scope for errors.

A scan at a workshop should offer up some answers, but before you do that, just check that you haven’t bumped the rotary four-wheel-drive selector dial and have triggered the system into a mode it doesn’t like being in right now.
