Reset Process Details

Bench Reset Procedure

Our bench reset service involves:

1. Module Reception: Secure packaging inspection and module identification
2. Bench Connection: Module connected to specialized programming hardware
3. Memory Reading: Complete EEPROM/Flash memory backup created
4. Crash Data Identification: Location of crash flags and event data in memory map
5. Data Clearing: Surgical removal of crash data while preserving calibration
6. Virgin State Restoration: Module returned to pre-crash configuration
7. Verification: Multiple read cycles confirm successful clearing
8. Testing: Functional validation on test bench before return

OBD Reset Capability

This module supports OBD-level diagnostics, but crash data clearing typically requires bench access for complete reset. OBD tools can clear some fault codes but often cannot remove hard crash events from non-volatile memory.

What Gets Reset

• ✓ Crash event counter (deployment history)
• ✓ Hard fault flags (permanent codes)
• ✓ Crash sensor activation data
• ✓ Module lock status (if applicable)
• ✓ Error counters and diagnostic status

What Remains Unchanged

• ✓ VIN coding (vehicle identification)
• ✓ Calibration data (deployment thresholds)
• ✓ Module serial number
• ✓ Hardware configuration
• ✓ Manufacturer programming

Post-Reset Requirements

After module reset and reinstallation:

• Clear any remaining DTCs using manufacturer scan tool
• Perform airbag system self-test (procedure varies by vehicle)
• Verify all sensors and components communicate correctly
• Road test to confirm airbag light remains off
• Some vehicles may require steering angle sensor calibration
