Preparation

Verify vehicle registration and inspection requirements for electric vehicles in your jurisdiction
Ensure vehicle battery has sufficient charge (at least 20%) for diagnostic procedures
Position vehicle on level surface in well-lit inspection area
Verify VIN matches registration documents

Procedure

1
Verify Vehicle Identification
Confirm the vehicle is a 2023 Chevrolet Bolt EUV battery electric vehicle. Check VIN plate on driver's side dashboard and door jamb sticker. Verify zero-emission vehicle (ZEV) classification on emissions label under hood or in door jamb.
2
Perform Visual Underhood Inspection
Open hood and verify presence of electric motor assembly, high-voltage battery system, and power electronics. Confirm absence of internal combustion engine components. Check for emissions control information label indicating zero-emission vehicle status.
3
Connect OBD-II Diagnostic Scanner
Locate OBD-II diagnostic port under driver's side dashboard. Connect OBD-II scanner to port. Turn vehicle to ON/READY mode without pressing brake pedal to power up vehicle systems.
4
Retrieve Diagnostic Trouble Codes
Use scanner to check for any active or pending diagnostic trouble codes (DTCs) related to high-voltage battery system, electric motor, power electronics, or vehicle emissions systems. Record all codes present. Note that zero active emissions-related codes should be present for inspection pass.
5
Verify Readiness Monitors
Check OBD-II readiness monitors status. For electric vehicles, verify that applicable monitors (typically limited to battery system and evaporative system if equipped) show 'Ready' or 'Complete' status. Most traditional ICE emissions monitors will not be supported on this BEV.
6
Inspect Evaporative Emissions System
Check for presence of small evaporative emissions control system for cabin climate control refrigerant. Verify no visible leaks or damage to A/C system components. This is typically the only emissions-related system on a fully electric vehicle.
7
Document Zero-Emission Status
Document that vehicle produces zero tailpipe emissions. Record VIN, odometer reading, and OBD-II scan results. Complete jurisdiction-specific emissions inspection certificate noting electric vehicle status and exemption or automatic pass criteria.
8
Disconnect Scanner and Complete Inspection
Turn vehicle off and disconnect OBD-II scanner. Close hood and verify all inspection documentation is complete. Apply inspection sticker or certificate as required by local regulations.

Reassembly

Ensure hood is properly closed and latched
Return vehicle to customer with emissions inspection documentation

Verification

Confirm no active diagnostic trouble codes are present in vehicle computer systems
Verify emissions inspection documentation correctly identifies vehicle as zero-emission battery electric vehicle
Ensure inspection certificate or sticker is properly completed and displayed per local requirements
