Toyota 30CM6101.cuw Firmware for 2014 Tundra
Toyota 30CM6101.cuw is an updated 2014 Tundra engine control calibration associated with a P2610 malfunction indicator light concern.
30CM6101.cuw is a Toyota engine control calibration associated with a P2610 malfunction indicator light concern on the 2014 Tundra. Toyota service bulletin T-SB-0146-16 lists calibration ID 30CM6101 as an updated calibration for that concern.
What the calibration relates to
The engine control module manages engine operation and monitors emissions-related systems. P2610 concerns the module’s internal engine-off timer performance. That timer helps the controller track how long the engine has been shut down, information used in onboard diagnostic checks.
The bulletin identifies 30CM6101 as an updated calibration in connection with the malfunction indicator light and P2610. It does not establish that the calibration changes the engine’s driving characteristics or adds a driver-selectable feature.
Diagnostic context
A malfunction indicator light can result from many different faults. P2610 gives a technician a more specific starting point than the warning light alone, while the current calibration ID helps identify the software installed in the controller. The presence of this updated ID in the bulletin does not by itself establish compatibility with every 2014 Tundra configuration.
