Toyota 30CM2200.cuw Firmware for 2014 Tundra
Learn how Toyota 30CM2200.cuw relates to a 2014 Tundra engine control update for diagnostic code P2610 and the malfunction indicator light.
30CM2200.cuw is an engine control calibration associated with a 2014 Toyota Tundra. Toyota lists calibration ID 30CM2200 as the updated calibration in service bulletin T-SB-0146-16, which addresses a malfunction indicator light and diagnostic trouble code P2610.
What the calibration controls
The engine control module manages engine operation and monitors systems for faults. P2610 concerns the module’s internal engine-off timer performance. That timer tracks elapsed time after the engine is switched off and supports the controller’s diagnostic monitoring. A detected problem can illuminate the malfunction indicator light, commonly called the check engine light.
Toyota identifies 30CM2200 as an updated calibration for the condition covered by the bulletin. The record supports its association with the P2610 warning-light issue, but does not specify every software change in the revision. A P2610 code should be assessed in the context of the applicable Toyota diagnostic procedure rather than treated as proof that this calibration alone will resolve the condition.
Catalog and vehicle context
The catalog filename is 30CM2200.cuw, while the service record lists the calibration identifier without the file extension. The documented vehicle is the 2014 Toyota Tundra. The record does not establish compatibility with every configuration of that model year, and it does not name a modified variant.
