APDTY 601313 is a brand-new front impact crash sensor for select 2003–2004 GM full-size SUVs and pickups, mounting on the radiator support at the front left or front right — for models WITHOUT a factory 2" body raise. It replaces GM numbers 85598001 and 15057506.
Key Takeaways
- What it is: a front impact/crash sensor — an SRS airbag-system component that mounts on the radiator support.
- Critical fitment check: this sensor is not compatible with models that have a factory 2" body raise. Those models use a different sensor, APDTY 601316.
- Fits: 2003–2004 Escalade, Avalanche, Silverado 1500/2500/3500, Tahoe, Denali, Sierra 1500/2500/3500, and Yukon — front left or front right position.
- Safety: this is an airbag (SRS) part. Diagnose with a scan tool and follow factory SRS procedures.

What does a front impact crash sensor do?
A front impact (crash) sensor detects the severity and characteristics of a frontal collision and reports that information to the airbag control module, which uses these signals to decide whether and how to deploy the airbags. It mounts to the radiator support, on either the front left or front right, depending on the specific application.
What are the symptoms of a failed crash sensor?
A faulty or damaged front impact sensor may cause:
- An illuminated airbag / SRS warning light
- A stored SRS trouble code referencing a front impact sensor circuit
- SRS faults after front-end collision damage or corrosion at the mounting location
A crash sensor is commonly replaced after collision damage or when diagnosis traces an SRS code to that sensor or its circuit. Proper diagnosis is required before replacement.
Does APDTY 601313 fit models with a body lift?
No — this is the most important fitment check. APDTY 601313 is not compatible on models with a factory 2" body raise. If your truck has the factory 2" body lift package, you need APDTY 601316 instead. Confirm which configuration your vehicle has before ordering.

- Follow SRS safety steps. Disconnect the battery and wait the manufacturer-specified time.
- Access the sensor at the radiator support, left or right per application.
- Install the new sensor, torque the fastener to factory spec, and fully reconnect the connector.
- Reconnect the battery, clear codes, and confirm the SRS light goes out.
Important safety warning
APDTY 601313 is a supplemental restraint system (SRS) component. Incorrect diagnosis, wrong parts, or improper installation can prevent proper airbag deployment. Use a scan tool capable of reading SRS codes and follow factory service procedures. If you are not equipped to service the airbag system, have the part installed by a qualified technician.
