What Does B2795 Mean?
B2795 indicates the Body Control Module (BCM) or Suspension Control Module has detected an electrical fault in the suspension control select switch circuit. This switch allows the driver to manually select different suspension modes (sport, comfort, normal, etc.) on vehicles equipped with adaptive or electronically adjustable suspension systems. The malfunction could be an open circuit, short to ground, short to power, or loss of communication between the switch and control module.
Common Causes
40%
Faulty suspension mode selector switch with internal contact failure or worn components
30%
Damaged or corroded wiring harness and connectors between switch and control module
20%
Failed Body Control Module (BCM) or Suspension Control Module with internal circuit damage
10%
Blown fuse or faulty relay in the suspension control switch circuit power supply
Diagnostic Steps
1
Step 1: Perform visual inspection of the suspension mode selector switch for physical damage, loose mounting, or worn button contacts. Check for signs of liquid intrusion or debris in the switch assembly.
2
Step 2: Use a digital multimeter to test for proper voltage supply at the switch connector (typically 5V or 12V reference voltage). Verify ground circuit continuity with less than 0.5 ohms resistance to chassis ground.
3
Step 3: Disconnect the switch connector and measure resistance values across switch terminals while actuating each mode position. Compare readings to manufacturer specifications (typically range from 0 to 10k ohms depending on position).
4
Step 4: Inspect wiring harness from switch to control module for chafing, pinching, or corrosion. Pay special attention to areas where harness passes through firewalls or near moving suspension components. Test for continuity and shorts using multimeter.
5
Step 5: Check fuses and relays associated with suspension control system in both underhood and interior fuse boxes. Test fuses for continuity and relays for proper operation.
6
Step 6: If all circuits test normal, perform control module communication test using advanced scan tool. Monitor live data for switch position inputs while operating selector. Replace switch if signal is erratic or missing, or replace control module if no communication exists.

The most common cause of B2795 (Suspension Control Select Switch Circuit Malfunction) is: Faulty suspension mode selector switch with internal contact failure or worn components
Typical repair costs for B2795 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive as the suspension system will default to a predetermined mode (typically comfort or normal). Driving dynamics and ride quality may be affected, but vehicle stability and safety are not compromised. Repair at earliest convenience.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2795 to identify the root cause.
