U0152 — Lost Communication With Side Restraints Control Module Left
vehicle network
Is it safe to drive?
Drive with caution The car drives normally, but with the SRS light on the airbags may not deploy in a crash. Treat it as a safety-critical repair: fine to drive to the shop, not fine to ignore for months.
How to diagnose with an OBD scanner
- Read the code and freeze frame Connect an OBD2 scanner, confirm U0152 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
- Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many U0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
- Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the airbag / restraint system (SRS) for damage, corrosion, chafing or poor contact.
- Subsystem check Read the SRS module with a scanner that supports airbag systems — generic OBD2 readers cannot see these codes.
- Subsystem check Inspect under-seat connectors — they are often disturbed by seat movement or cleaning.
- Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm U0152 does not return.
Approximate repair cost
Repair cost depends on which component actually failed. Typical scenarios for U0152 (parts and labor, USD, independent shop rates): SRS module reset or replacement: $300–$1,000; Reconnect or repair SRS wiring/connectors: $80–$250; Replace a sensor or clockspring: $150–$500. Overall, fixing U0152 usually costs between $80 and $1,000. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.
Common questions
Will U0152 clear itself?
Sometimes U0152 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.
How much does it cost to fix U0152?
SRS module reset or replacement — $300–$1,000; Reconnect or repair SRS wiring/connectors — $80–$250; Replace a sensor or clockspring — $150–$500. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What are the symptoms of U0152?
Drivers most often notice: airbag (SRS) warning light on, no other driving symptoms, airbag system disabled message.
How do I diagnose U0152 myself?
Start with a scan: confirm U0152, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the airbag / restraint system (SRS), and verify the suspect component against live data before buying parts.
What does U0152 mean?
When U0152 appears on a scan, it means the control module has flagged a problem in the airbag / restraint system (SRS): lost communication with side restraints control module left. The fault sits in the vehicle network group of the OBD2 standard.
To set U0152, the control module compares live readings of the airbag / restraint system (SRS) against calibrated limits, usually over several drive cycles. Alongside the code it stores a freeze frame — a snapshot of rpm, load, coolant temperature and vehicle speed at the moment of failure. Reading that snapshot first saves diagnostic time.
What causes U0152?
- faulty impact or occupancy sensor
- depleted backup battery or low system voltage
- damaged wiring under seats or in the steering column
- failed clockspring (driver airbag circuit)
Common symptoms of U0152
- airbag (SRS) warning light on
- no other driving symptoms
- airbag system disabled message
