Tech is replacing a clockspring on a 2013 Accord.

Mistake Ranking (most to least critical):

1. Probing the yellow airbag connector with a test light — This is the most dangerous error. Test lights can send voltage/current into the airbag circuit, potentially triggering deployment. Airbag systems must only be tested with a proper diagnostic scanner or ohmmeter (power off). Serious injury/death risk.

1. Setting the airbag face-down on the bench — Airbags are stable only when properly mounted. If it deploys while face-down, the force can cause it to rocket off and explode, sending shrapnel. Always place airbag face-up on a flat, stable surface, away from flammable materials.

1. Not waiting after battery disconnect before handling airbag — Airbag systems retain backup power via capacitors. Disconnecting the battery isn’t enough; you must wait at least 10–15 minutes (per most OEM service manuals, including Honda) to allow capacitors to discharge before removing the airbag.

1. Unbolting the airbag immediately after battery disconnect — Same as above. Rushing this step risks accidental deployment due to residual energy.

Correct Procedure Summary:

• Disconnect battery negative.
• Wait 10–15 minutes.
• Remove airbag carefully, place face-up on bench.
• Never use a test light on airbag circuits—use a diagnostic tool or multimeter (with power off).
• Follow torque specs when reinstalling.

This job requires strict adherence to safety protocols—airbag systems are unforgiving. If unsure, consult the factory service manual or defer to a certified technician.

Ranked by severity (1 = most dangerous):

1. Probing the yellow connector with a test light (Critical). SRS circuits are extremely sensitive to induced voltage/current. A test light applies battery voltage/current directly to the inflator squib. This can deploy the airbag instantly, causing severe injury or death. Honda SRS Service Manual: "Do not use a test light... use only the SCS service connector and HDS." (Ref: 2013 Accord SRS Section, "Precautions").

1. Setting the airbag face-down on the bench (Critical). If the module deploys (static, induced voltage, or mistake #1), the module becomes a projectile. The plastic horn pad/cover becomes shrapnel. Standard Industry Practice (I-CAR/SAE): "Always place airbag module face up on a clean, flat surface."

1. Immediately unbolting the airbag after battery disconnect (Procedural Violation). The SRS capacitor backup power supply requires time to discharge. Honda specifies a wait time (typically 3 minutes minimum) after battery disconnect before touching SRS connectors. Honda Service Manual: "Wait at least 3 minutes after disconnecting the battery negative cable before starting work."

1. Disconnecting only the negative battery terminal (Incomplete Isolation). Best practice for SRS work is disconnecting both terminals (negative first, then positive) and isolating them to prevent accidental reconnection or ground paths through the chassis.

Correct Procedure Summary: Disconnect (-) then (+) battery → Wait 3+ mins → Remove airbag (face UP on bench) → Use HDS/SCS tool only for diagnostics. Never probe yellow connectors with a multimeter or test light.
