What Does B2222 Mean?
This code indicates that the Body Control Module (BCM) has detected an excessive current draw from the passenger rear window motor circuit, exceeding the programmed threshold. This typically occurs when the window motor or its circuit is drawing more amperage than normal during operation, suggesting mechanical binding, a short circuit, or a failing motor. The BCM monitors current feedback to protect the circuit from damage and prevent component failure.
Common Causes
35%
Binding or seized window regulator mechanism causing excessive motor load
30%
Failing or shorted window motor with internal winding damage
20%
Short to ground in window motor wiring harness or connector
10%
Debris or obstruction in window track causing mechanical resistance
5%
Faulty Body Control Module power output circuit
Diagnostic Steps
1
Step 1: Perform visual inspection of passenger rear window operation - manually operate window while listening for binding, grinding, or slow movement. Check for visible obstructions in door panel and window track.
2
Step 2: Using a digital multimeter, measure current draw on the window motor circuit during operation (normal draw is typically 3-8 amps depending on vehicle). Compare to manufacturer specifications and note if current exceeds 10-12 amps.
3
Step 3: Disconnect the window motor connector and inspect pins for corrosion, damage, or signs of overheating. Measure resistance across motor terminals (should be 2-6 ohms typically) and check for short to ground on both motor wires.
4
Step 4: Remove door panel and inspect window regulator for binding, broken cables, worn rollers, or misalignment. Check window track for debris, damage, or poor lubrication that could cause excessive resistance.
5
Step 5: If mechanical components appear normal, perform a BCM output test using scan tool to command window operation while monitoring live current feedback data to isolate BCM versus motor/circuit fault.
6
Step 6: After repairs, clear codes and cycle window through full up/down operation multiple times while monitoring current draw to verify repair and ensure no excessive feedback is detected.
Estimated Repair Cost

The most common cause of B2222 (Window Passenger Rear Current Feedback Exceeded) is: Binding or seized window regulator mechanism causing excessive motor load
Typical repair costs for B2222 range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This is safe to drive as it only affects passenger rear window operation. The window may become inoperative or the BCM may disable the circuit to prevent damage. Non-urgent repair, but should be addressed to restore full vehicle functionality and prevent potential water intrusion if window becomes stuck in open position.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2222 to identify the root cause.
