What Does U0532 Mean?
The control module receiving data from the rain sensing module has detected corrupted or illogical information on the vehicle's communication network. This affects automatic wiper operation based on rain detection.
Common Causes
40%
Faulty rain sensor module or contaminated sensor optical surface
25%
Damaged wiring or connector to rain sensor behind rearview mirror
20%
CAN bus communication fault on interior network
10%
Poor power supply or ground connection to rain sensor module
5%
Body control module configuration or software calibration issue
Diagnostic Steps
1
Step 1: Check rain sensor module communication status and verify sensor reading values in live data
2
Step 2: Inspect rain sensor optical surface on windshield for contamination, adhesive issues, or damage
3
Step 3: Test rain sensor connector behind rearview mirror for proper connection and terminal integrity
4
Step 4: Measure CAN bus signals at rain sensor module location for proper voltage levels
5
Step 5: Clean sensor lens area and replace rain sensor module if communication fault persists
Estimated Repair Cost
$150 - $400
Parts + labor, varies by vehicle and location
The control module receiving data from the rain sensing module has detected corrupted or illogical information on the vehicle's communication network. This affects automatic wiper operation based on rain detection.
The most common cause of U0532 (Invalid Data Received From Rain Sensing Module) is: Faulty rain sensor module or contaminated sensor optical surface
Typical repair costs for U0532 range from $150 to $400, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Automatic wiper function will not work properly. Driver can still manually operate wipers, minimal safety impact if driver is attentive to weather conditions.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0532 to identify the root cause.
