Documentation and scope
94 alarm headings extracted from Thermo King SR-3 Truck Multi-Temperature Diagnostic Manual TK 54293-1-OD-EN, Revision F (June 2024), Section 5. This manual includes detailed diagnostic procedures for most listed alarms. For 75 alarms, numbered diagnostic tests from the OEM manual are displayed as interactive steps; the other 19 link to their OEM sections. Some tests reference additional service procedures, tables, or wiring diagrams and must be completed using the original manual. No unverified resistance, voltage or pressure thresholds are supplied.
The separately bundled 2015 TK 40933-8-CH alarm chart is a cross-model quick reference, not an OEM model-specific troubleshooting procedure. Other SR-4 and Precedent alarm trees require their own manuals and validation.
