About B0160

The B0160 code indicates that the body control module has detected a push button start switch circuit malfunction condition. This relates to the vehicle's body electrical systems, which control comfort, convenience, and safety features. When this code is stored, the affected system or component may not operate correctly, potentially impacting safety or comfort features. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: Airbag warning light illuminated on dashboard. Audio system not powering on. Turn signals flashing rapidly or not at all. Door locks not responding to remote or switch. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: Corroded battery terminals. Faulty SRS/airbag control module. Failed window/lock/seat motor. Water intrusion into electrical connectors. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Connect an OBD-II scanner and read all stored body control module trouble codes. Inspect the affected circuit fuse and relay; replace if blown or faulty. Check the wiring harness and connectors for damage, corrosion, or loose pins. Test circuit voltage and ground with a multimeter at the affected component. Verify battery voltage is within specification (12.4V+ engine off). If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
