B0100 Error: Short in D Squib Circuit - 2005 Chevrolet Cobalt | SRS System Issue
I recently shut off my 2005 Chevrolet Cobalt while parked on a hill in reverse. After attempting to restart the vehicle and placing it in park, the check engine light illuminated, and the car would not turn over at all. The diagnostic tool displayed code B0100, which reads 'short in D squib circuit'. I'm unsure how this relates to my situation, but I'd like to know what steps I should take to troubleshoot this issue. Any insights or recommendations for a safe and effective fix? Thanks in advance!
Code B0100 is an SRS (Supplemental Restraint System) fault, indicating a potential short in the D squib circuit. This typically points to an issue within the clockspring or steering wheel wiring harness. While it's possible this could affect engine startability, the primary concern is safety related to airbag deployment. I strongly recommend having a certified professional inspect and diagnose this issue—DIY repairs on SRS components are not advised due to serious safety risks. Could you confirm if there are any other diagnostic codes present? Also, were there any specific actions taken during parking or shifting that might have contributed to the fault?
