Next, apply Clearing Procedures Guidelines to erase relevant codes only after confirming safety verification checks are satisfied, ensuring all modules report no active faults. Maintain traceability by documenting codes read, actions taken, and the final confirmation of a clean readout.
Fault Code Readout Steps
Fault code readout is the starting point for diagnosing SRS wiring issues: you’ll connect the scanner, retrieve stored and current codes, note the exact codes and freeze frame data, and prepare to clear codes only after verifying mechanical and electrical conditions meet safety and repair standards.
- Use diagnostic tools properly to capture all active and historical fault data.
- Record fault code definitions clearly, distinguishing between P-, B-, C-, and U-codes for precise direction.
- Verify freeze frame data reflects current conditions before proceeding.
- Confirm no conflicting codes remain and that power, grounding, and sensor integrity meet standards.
This disciplined approach guarantees you preserve safety margins while you prepare for the next steps in clearing procedures.
Clearing Procedures Guidelines
Clearing fault codes should only occur after you’ve verified that mechanical repairs and electrical conditions meet all safety and performance standards. You perform fault code readout with structure, then proceed to clearing using documented steps and limits. You confirm fault presence, document codes, and guarantee no pending or intermittent faults remain. You then clear per procedure, re-scan to confirm reset success, and log outcomes for traceability. If codes return, reassess wiring harness maintenance and SRS wiring integrity before reattempt. Maintain strict sequence to avoid masking faults. This approach reflects SRS troubleshooting techniques and emphasizes disciplined, repeatable actions. Expect consistency, not guesswork, and preserve system readiness through careful validation and controlled testing.
