What Does U0506 Mean?
Door Control Module G (typically right sliding door in vans/minivans) is transmitting invalid or corrupted data on the vehicle network. Communication exists but the data content is unreliable or out of specification.
Common Causes
35%
Defective right sliding door control module needing replacement
25%
Connector corrosion or terminal damage at right slider module connection
20%
Broken wires in right sliding door harness from repeated door cycles
12%
Voltage supply issues during power door motor activation causing data corruption
8%
Module programming error or sensor calibration fault
Diagnostic Steps
1
Step 1: Measure voltage at right sliding door module during all phases of door operation; check for drops or spikes
2
Step 2: Carefully inspect harness routing through door track for pinched, chafed, or broken wires
3
Step 3: Command right sliding door functions with scan tool while monitoring data parameters for inconsistent values
4
Step 4: Test CAN bus resistance and signal voltage at module G connector; compare to left side if applicable
5
Step 5: Perform module initialization/programming procedure; replace module G if invalid data transmission persists
Estimated Repair Cost
$200 - $800
Parts + labor, varies by vehicle and location
Door Control Module G (typically right sliding door in vans/minivans) is transmitting invalid or corrupted data on the vehicle network. Communication exists but the data content is unreliable or out of specification.
The most common cause of U0506 (Invalid Data Received From "Door Control Module G") is: Defective right sliding door control module needing replacement
Typical repair costs for U0506 range from $200 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Right power sliding door may malfunction or operate unpredictably. Manually secure door if automatic operation fails to prevent unintended opening during vehicle operation.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0506 to identify the root cause.
