Key finding
Current steering-lock/start-authorization fault detected
The scan found one current BCM fault related to the steering-lock/start-authorization system. Several older communication and low-voltage codes were also stored. These findings point toward the vehicle's electronic start-authorization/control system as the main area requiring further diagnosis. The scan does not prove that the starter, BCM, steering-lock unit, or any other single component has failed.
Reported condition
Why the vehicle was scanned
- Ignition powers on normally
- Engine does not crank
- No starter engagement
- Cluster displayed a KEY SYSTEM warning during the start attempt
Owner reported that previous work had already been attempted in the steering-column / steering-lock area. Exact prior work was not available for review at the time of this report.
Prior work is context only. This report does not claim that it caused the present condition.

Primary / complaint-relevant findings
B26EF Steering lock relay off Current Details
Exact scan evidence
BCM | B26EF | Steering lock relay off | Current
What it means
Research interpretation
The Body Control Module reported that the steering-lock relay was off when this module was scanned.
Why it matters
This is the only supplied code marked Current. It concerns the steering-lock and start-authorization system, which closely matches the no-crank and KEY SYSTEM complaint.
What this code does not prove
It does not prove that the steering-lock unit, BCM, starter, relay, wiring, or another single component has failed.
Common diagnostic areas
- Steering-lock and start-authorization system
- Power supply and grounds
- Related wiring, connectors, relay control, and module communication
These are source-supported areas for a technician to evaluate, not identified causes.

Exact scan evidence
BCM | B2193 | Chain of BCM-ECM | Past
What it means
Research interpretation
The vehicle previously recorded a communication or start-authorization issue between the Body Control Module and Engine Control Module.
Why it matters
This code belongs to the immobilizer and start-authorization relationship and provides context for the no-crank complaint.
What this code does not prove
It does not prove that either the BCM or ECM is defective. Some applicable service information notes that the code may also be stored during key-registration procedures.
Common diagnostic areas
- BCM-to-ECM authorization communication
- Immobilizer and key registration context
- CAN communication
These are source-supported areas for a technician to evaluate, not identified causes.
Sources, confidence and applicability
- Model-specific service contextInfiniti security-system service information

The cited service examples explain the system relationship but are not confirmed as exact diagnostic procedures for this 2011 Infiniti M37.
U1000 CAN communication Past Details
Exact scan evidence
BCM | U1000 | CAN communication | Past
What it means
Research interpretation
The vehicle previously recorded a communication problem on the network used by its electronic control modules.
Why it matters
Infiniti service guidance says CAN communication codes should be evaluated before downstream network-related codes. Low voltage can also interrupt module communication.
What this code does not prove
It does not prove that the module storing U1000 is faulty. Manufacturer guidance notes that the reporting module may still be operating normally while the network error is external to it.
Common diagnostic areas
- CAN network communication
- Module power and grounds
- Battery voltage, connectors, wiring, and configuration
These are source-supported areas for a technician to evaluate, not identified causes.
Sources, confidence and applicability

B2562 Low voltage Past Details
Exact scan evidence
BCM | B2562 | Low voltage | Past
What it means
Research interpretation
The Body Control Module previously recorded a low-voltage condition.
Why it matters
Historical low voltage can help explain why several electronic modules stored communication or control-related codes.
What this code does not prove
It does not prove the battery is currently weak or identify the source of the earlier voltage condition.
Common diagnostic areas
- Battery condition at the time of diagnosis
- BCM power and ground
- Charging and power-distribution context
These are source-supported areas for a technician to evaluate, not identified causes.
Sources, confidence and applicability

Interpretation
What the scan suggests
The strongest current finding is B26EF in the Body Control Module, related to the steering-lock/start-authorization system. Historical BCM-to-ECM communication, CAN communication, steering-lock relay, and low-voltage codes provide additional context. Because the engine does not crank at all, these findings support further diagnosis of the electronic start-authorization / steering-lock / power-and-communication path before replacing components based on guesswork.
What the scan did not establish
- A failed starter
- A failed BCM
- A failed ECM
- A failed steering-lock unit
- A failed IPDM
- A failed battery
- The exact root cause of the no-crank condition
