U0153

Lost Communication With Side Restraints Control Module - Right

Network / communication Generic OBD-II Medium

What it means

U0153 means the restraints system has lost communication with the right-side restraints control module — the controller for the passenger-side airbags and side restraint devices. It turns on the airbag warning light and can disable right-side deployment, so the protection may not work in a crash even though the car drives normally. It is usually caused by a wiring or connector fault, a lost power or ground feed, or a failed module, and should be treated as a safety-priority repair.

Medium

Can I keep driving? The car drives, but the airbag light is on and the right-side restraints may not deploy in a crash — a real safety risk, so repair it promptly.

How to diagnose & fix

Work through it in order

Scan the SRS system and confirm whether the right side restraints module responds.
Check power and ground at the module and any dedicated fuse.
Inspect the module's connector and wiring for corrosion, damage, or water, especially in the sill area.
Check the bus circuits between the module and the restraints controller for opens or shorts.
If power and wiring are good but the module stays silent, replace it, then clear and re-test with a proper SRS scan tool.

FAQ

Quick answers

Is it safe to drive with U0153?+

The vehicle drives, but the right-side airbags may not fire in a crash while this code is present, so it's a genuine safety issue that should be fixed promptly.

Can I just clear U0153?+

You shouldn't rely on that — if the module or wiring is faulty the airbag light and disabled protection return; SRS faults need to be properly repaired, not just cleared.
