Accurate Left Rear Seat Belt Switch Circuit

There's an issue with the left rear seat belt switch.

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)

This code means the computer isn't getting a proper signal from the left rear seat belt switch, which tells whether the seat belt is buckled or not.

What the computer is actually seeing

The computer expects a near zero-volt signal when the seat belt is unbuckled and around 5 volts when buckled.

What a healthy reading looks like

0V (unbuckled) to 5V (buckled) from the seat belt switch.

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.

  1. 1Check seat belt switch wiring for damage or disconnection.
  2. 2Inspect the connector at the seat belt switch; ensure it's clean and secure.
  3. 3Measure the voltage at the seat belt switch connector while buckling and unbuckling; expect 0V unbuckled and near 5V buckled.
  4. 4If voltage readings are off, replace the seat belt switch. If readings are good but the code persists, suspect a faulty SRS control module.

Common causes

  • Wiring issue or short to ground in the seat belt switch circuit
  • Faulty seat belt switch
