What Does U0219 Mean?
The control module has lost communication with door switch E on the vehicle's network bus. This indicates a network communication failure between the body control module and a specific door switch module, typically affecting a rear passenger door.
Common Causes
35%
Wiring harness damage, chafing, or connector corrosion in door jamb area
30%
Failed door switch module or control unit
20%
Poor ground connection at door module
10%
CAN bus network fault or termination resistor issue
5%
Body control module software or hardware fault
Diagnostic Steps
1
Step 1: Inspect door jamb wiring harness for visible damage, breaks, or chafing where door opens and closes
2
Step 2: Check all connectors at door switch module for corrosion, pushed-out pins, or water intrusion
3
Step 3: Using scan tool, attempt to communicate directly with door switch E module and check for response
4
Step 4: Measure voltage and ground at door switch module connector; verify power supply (typically 12V) and clean ground (less than 0.1V)
5
Step 5: Check CAN bus continuity and resistance between door module and body control module (should read 60-120 ohms with modules disconnected)
Estimated Repair Cost
$150 - $600
Parts + labor, varies by vehicle and location
The control module has lost communication with door switch E on the vehicle's network bus. This indicates a network communication failure between the body control module and a specific door switch module, typically affecting a rear passenger door.
The most common cause of U0219 (Lost Communication With "Door Switch E") is: Wiring harness damage, chafing, or connector corrosion in door jamb area
Typical repair costs for U0219 range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
No direct safety concern, but may affect door lock/unlock functions, interior lighting, and window operation. Vehicle remains safe to drive.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0219 to identify the root cause.
