🛠️ Typical diagnostic steps (short version)

1. Scan with G-IDSS or a capable bi-directional tool.
2. Check for any other SRS codes (e.g., B101A30, B101B30).
3. Visually inspect the front impact sensor harness for chafing or water damage.
4. Measure voltage at the sensor connector – should not be battery voltage when ignition is ON.
5. Compare resistance values with known good sensor.
6. Clear code and test drive – if returns, replace impact sensor or repair short.

Step 1: Clear & Retest

• Use a professional scanner (e.g., Launch X431, Autel MaxiCOM, or Isuzu GDS).
• Clear codes and test drive until “hot” (30+ minutes in Thai traffic).

Prevention Tips for Hot Climate

• Park in shade or use a windshield sunshade – reduces heat stress on steering wheel electronics.
• Avoid rotating steering wheel excessively when engine is off.
• Never use silicone-based lubricants near airbag connectors.
