What Does U0508 Mean?
The receiving control module has detected invalid or corrupted data from the moveable roof control module. This communication error prevents proper data exchange on the vehicle's network bus.
Common Causes
35%
Moveable roof control module failure or internal circuit malfunction
30%
Corroded or damaged connectors and wiring in roof control circuit
20%
Voltage supply or ground circuit fault to moveable roof module
10%
CAN bus communication line short or open circuit condition
5%
Module programming error or incompatible software version
Diagnostic Steps
1
Step 1: Monitor moveable roof control module data parameters using scan tool to identify which data is invalid
2
Step 2: Verify power and ground circuits to moveable roof control module meet specifications
3
Step 3: Inspect all connectors and wiring associated with moveable roof module for water intrusion, corrosion, or physical damage
4
Step 4: Test CAN bus communication lines for proper voltage, resistance, and continuity between modules
5
Step 5: Replace or reprogram moveable roof control module if all circuits test normal
Estimated Repair Cost
$150 - $1,500
Parts + labor, varies by vehicle and location
The receiving control module has detected invalid or corrupted data from the moveable roof control module. This communication error prevents proper data exchange on the vehicle's network bus.
The most common cause of U0508 (Invalid Data Received From Moveable Roof Control Module) is: Moveable roof control module failure or internal circuit malfunction
Typical repair costs for U0508 range from $150 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Primarily a convenience issue. Moveable roof may not operate, potentially leaving occupants exposed to weather. Roof could potentially open or close unexpectedly if communication is intermittent.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0508 to identify the root cause.
