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 issued service information and extended coverage on related steering lock failures across Nissan platforms, and owner complaints/forum reports 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.
