What Does B2368 Mean?
DTC B2368 indicates that the Body Control Module (BCM) has detected a voltage or resistance signal from the steering column switch assembly that falls outside the expected operating range. This code affects the steering column-mounted controls, which may include turn signals, wipers, cruise control, and multifunction switches. The BCM monitors the switch circuits and sets this code when it detects a short circuit, open circuit, or signal value that doesn't match any programmed switch position.
Common Causes
45%
Faulty multifunction switch or clockspring assembly with internal short or open circuit
30%
Damaged, corroded, or loose wiring harness connector at steering column switch
15%
Corroded or damaged pins in the Body Control Module connector related to steering column circuits
10%
Failed Body Control Module with internal circuit fault
Diagnostic Steps
1
Step 1: Perform visual inspection of all steering column switch connectors for corrosion, pushed-out pins, or water intrusion. Disconnect and inspect the multifunction switch connector and clockspring connector for damaged terminals or signs of overheating.
2
Step 2: Using a digital multimeter, measure the resistance values at the steering column switch connector (BCM side disconnected) while cycling through all switch positions. Compare readings to manufacturer specifications, typically ranging from 0 ohms to several thousand ohms depending on switch position.
3
Step 3: With ignition on and switch connector reconnected, use a multimeter to backprobe the signal wires at the BCM connector and verify proper voltage reference (typically 5V or 12V) is being supplied to the switches. Check for voltage drops or intermittent signals while manipulating the steering column and switches.

Step 4: If all wiring and voltage checks are normal, test the multifunction switch assembly in isolation by connecting it to a bench power supply with appropriate voltage and measuring output signals through each switch function. Replace the switch assembly if values are out of range.

Step 5: Clear the code and perform a functional test of all steering column switches including turn signals, wipers, cruise control, and any other integrated functions. Road test the vehicle while monitoring live data to ensure the code does not return and all switch functions operate correctly.
Estimated Repair Cost

The most common cause of B2368 (Steering Column Switch Circuit Out of Range) is: Faulty multifunction switch or clockspring assembly with internal short or open circuit
Typical repair costs for B2368 range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The vehicle is generally safe to drive, but critical functions like turn signals, wipers, or cruise control may be inoperative or function intermittently, which creates a safety hazard especially in poor weather or traffic conditions. Repair should be completed within a few days to restore full vehicle functionality and safety systems.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2368 to identify the root cause.
