Diagnostics Guide
Interpret runtime control, telemetry, CAN, and system panels to identify behavior mismatches quickly.
Panel Purpose
- Control: mode, controller enabled, broadcast, generation.
- Spec / Act: requested lock versus measured engagement.
- Vehicle: speed, rpm, throttle, boost, clutch reports.
- CAN: readiness, bus status, last frame ages.
- Haldex TX Frames: generated frame diagnostics and payload snapshots.
- System: uptime, STA/AP info, hostname, internet reachability.
Triage Flow
- Check CAN readiness and stale-frame indicators first.
- Compare Spec/Act during known engagement events.
- Validate network/system before assuming control-path failures.
- Escalate to CAN View + logs for detailed capture if mismatch persists.
