Dealing with Wonky Readings
Inconsistent or erratic readings from your scan tool? That’s a real buzzkill when you’re hunting down airbag issues. Faulty sensors might be sending wacky signals to the airbag control module. Check those sensors, wires, and connections to get to the bottom of it.
Electromagnetic interference (EMI) could also be messing things up. Shield your tool and wires, and ensure the car’s electrical system is well-grounded. If the airbag control module’s acting up, scan for error codes and update its software. Problem solved!
Checking Pins and Wiring Like a Pro
Good pin connections and solid wiring are the backbone of accurate airbag diagnostics. I’ve seen it all—loose pins or damaged wires can throw everything off. Start by inspecting the scanner’s pins and the car’s wiring harness. Look for anything bent, broken, or loose.
- Examine all pins and terminals in the SRS system—they’re plated for low-energy circuits, so treat ’em gently.
- Use a repair kit (like the J-38125 SIR/SRS) to fix any damaged bits.
- Slap on some dielectric grease (GM P/N 12345579) when reassembling for solid contact.
After repairs, clear those Diagnostic Trouble Codes (DTCs) and check for stragglers. If codes pop back up, dig deeper into the troubleshooting steps.
| DTC Code | What It Means |
|---|---|
| B0012 | Left B-Pillar Sensor – Circuit High |
| B0013 | Left B-Pillar Sensor – Circuit Low |
| B0015 | Right B-Pillar Sensor – Circuit High |
