Frustrated by flickering dashboard lights or doors that won’t lock in your 2015 Chevrolet Silverado? These glitches often point to a failing body control module, disrupting everything from power windows to security systems. Over my 20+ years fixing GM trucks, I’ve tackled hundreds of BCM failures, many triggered by moisture ingress or voltage spikes during rough off-road hauls. If you’re asking, “how to diagnose BCM issues in a 2015 Silverado,” start with scanning for codes like U0140 or B1325 using an OBD-II tool. This pre-programmed BCM, part number 13587704, resolves those headaches by cloning data from your original unit. We handle the programming after you ship us your old module, ensuring seamless integration without dealership costs. Compatible with numbers like 13592137, 13506935, 13506936, and 13594764, it fits various GM models. This approach saves you $200-500 compared to new units, plus it restores reliable performance for daily drives or towing jobs.

Body control modules in 2015 Silverados commonly fail due to electrical shorts or corrosion, especially in high-humidity areas. Symptoms include intermittent wipers, non-functional remote starts, or persistent airbag lights. In my shop, I’ve seen over 300 cases where voltage fluctuations from faulty alternators accelerated BCM wear, leading to no-start conditions.

This cloned BCM directly addresses these by transferring your vehicle’s exact configuration, eliminating communication errors with other modules like the ECM.

• Erratic lighting: Restores stable relay control, preventing random dimming.
• Security system faults: Re-syncs immobilizer data to avoid theft deterrent lockouts.
• Accessory failures: Fixes power distribution for windows, locks, and mirrors.

Real Customer Story: A fleet owner with a 2015 Silverado 1500 reported constant door lock issues during deliveries. After cloning and installing this BCM, his truck ran flawlessly, cutting downtime by 80%.

This BCM arrives cloned to your specs, backed by a one-year warranty. We contact you post-purchase to arrange shipping your original unit; once received, we program and return it with tracking.

Benefits include cost savings—no need for expensive dealer programming—and quick turnaround, often within days. It supports features like optional AVF model year breakpoints in compatible SUVs.

Pro Tip: Before replacement, check for water damage under the steering column, a common culprit in Silverados; sealing harnesses can prevent future failures.

Replacing the BCM in your 2015 Silverado takes about 30-60 minutes with basic tools. Locate it under the steering column, disconnect the battery, and swap units carefully to avoid static damage.

Post-install, perform these relearn steps for GM standards:

1. If no-start occurs, do a theft relearn: Insert key, turn to ON for 10 minutes, off for 5 seconds; repeat three times.
2. Reset airbag warning: Use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ procedure.
3. Recalibrate brake pedal if needed: Follow your manual or tech guidance for optimal safety.

Steps vary by model; consult a pro if unsure. This ensures full functionality, from braking response to system sync.

Compatible with:

• 2015 Chevrolet Silverado (under steering column, ID 13587704)
• Other GM models like 2015 Sierra 1500, Tahoe with opt AVF, Impala 2015-16 (VIN 1, LH dash), and more.

Verify part numbers; provide VIN for confirmation. No core charge required.
