B2190 on Nissan by model: symptoms, diagnosis and fix
A documented no-start condition on push-button-start Rogues can occur when the electronic steering column lock (ESCL/steering lock unit) fails and the vehicle will not transition to READY/ON normally. Owners report the key fob is recognized but the ignition stays stuck, often with a steering lock warning or inability to turn the vehicle on. Nissan's ESCL warranty extension (6 years/unlimited miles, 2013) covered only 2009 Altima and Maxima and explicitly does not apply to other models such as the Rogue, but owner complaints filed with NHTSA include Rogue vehicles in this generation.
Common Symptoms
- Vehicle will not start with push button
- Key fob recognized but ignition does not turn on normally
- Steering lock warning or security indicator illuminated
- Intermittent no-start that becomes permanent
- Need to repeatedly press start button before vehicle responds
How to Fix
Diagnosis typically includes confirming battery condition, checking Intelligent Key operation, and scanning BCM/IPDM/steering lock related data for lock status. Repair usually involves replacing the steering lock assembly and performing initialization/reprogramming as required; in some cases the lock is bypassed or a fuse workaround is discussed by owners, but proper repair is replacement and registration of the unit.
Owner tips & cautions
- TipOwners commonly recommend scanning BCM data with a Nissan-capable scan tool to confirm steering lock status before replacing parts.
