B1325 on Chevrolet
Device / Control Module Power Circuit Voltage Out of Range
B1325 on Chevrolet vehicles indicates device / control module power circuit voltage out of range. Au7o has documented this code across 1 Chevrolet model — most commonly on Suburban. This is a manufacturer-specific body code (common on GM and others) indicating a control module detected its supply voltage outside the acceptable range, typically too low or too high. Modules need a stable voltage (roughly within battery/charging norms); readings that drop too low or spike too high trigger this code. The most frequent real-world cause is a weak battery or charging problem, especially in cold weather. Symptoms depend on the affected module, and the charging system and battery should be checked first. Typical repair costs on Chevrolet range from $150 to $800, depending on the specific model and root cause.
Common Causes of B1325
- •Weak, discharged, or failing battery
- •Charging system/alternator fault (over- or under-charging)
- •Corroded or loose battery terminals and grounds
- •Poor power or ground connection to the module
- •Damaged wiring in the module power circuit
- •High resistance connections causing voltage drop
B1325 on Chevrolet by Model
Chevrolet Suburban(1 issue)
- Steering Column Lock and Click Noise2015-2025
The 2015+ Suburban uses an electronic steering column lock that can malfunction, causing a clicking noise from the steering column, failure to recognize the key fob, or preventing the vehicle from starting. The electronic lock module replaces the traditional key-cylinder lock and communicates with the body control module (BCM) to verify the key fob is present before allowing the engine to start. When the lock module fails, it may click repeatedly without unlocking, or it may not engage at all, leaving the steering unlocked even when the vehicle is off.
