Left Front Impact Sensor Circuit Range/Performance Problem
There’s a problem with the left front impact sensor circuit.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The airbag control module isn't getting the right signals from the left front impact sensor, which detects collisions to deploy airbags.
What the computer is actually seeing
The airbag control module monitors the voltage from the left front impact sensor, expecting specific voltage readings during normal operation and crash conditions. A significant deviation indicates a fault.
What a healthy reading looks like
Normal voltage readings from the left front impact sensor should be between 0.5V and 4.5V under normal conditions.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the wiring and connectors for the left front impact sensor. Look for frays, corrosion, or disconnections. Decision: If damaged, repair or replace wiring/connectors. If okay, proceed.
- 22. Measure the voltage on the impact sensor using a multimeter while hitting the sensor or simulatively applying impact. Expect 0.5V-4.5V under normal conditions. Decision: If voltage out of range, replace the sensor. If within range, proceed.
- 33. Check for any additional DTCs stored in the airbag control module. Decision: If other codes are present that relate to the airbag system, address those as well. If only B006C is present, proceed to next step.
- 44. Test the airbag control module functionality using a scan tool. Decision: If module shows failure, replace it. If it tests good, the issue may be resolved. Check for proper resets.
Common causes
- Damaged wiring or connectors in the impact sensor circuit.
- Faulty left front impact sensor.
- Airbag control module malfunction.

Frequently asked questions
Is it safe to drive with this code active?
Yes, but it may affect airbag deployment in a collision. Get it checked soon.
Will the code come back after clearing it?
It may return if the underlying issue isn't resolved.
Why did this code appear after a minor accident?
Impact sensors may trigger faults even in minor collisions if they detect abnormal signals.
