What Does U1137 Mean?
This code represents a duplicate or secondary detection of invalid or missing telltale data on the SCP network. It often appears when multiple modules detect the instrument cluster communication failure or indicates a different aspect of telltale data loss.
Common Causes
35%
Instrument cluster module failure
25%
SCP network circuit fault affecting multiple modules
20%
Body Control Module not receiving telltale acknowledgment
12%
Cluster connector corrosion or terminal damage
8%
Software corruption in instrument cluster
Diagnostic Steps
1
Step 1: Determine which module set U1137 versus U1136 to identify data flow direction
2
Step 2: Compare telltale status between scan tool data and actual cluster display for mismatches
3
Step 3: Check for intermittent connections by wiggle-testing cluster and network connectors
4
Step 4: Verify SCP bus voltage remains stable during telltale activation sequences
5
Step 5: Attempt cluster software reflash or initialization if supported by manufacturer
Estimated Repair Cost
$150 - $900
Parts + labor, varies by vehicle and location
This code represents a duplicate or secondary detection of invalid or missing telltale data on the SCP network. It often appears when multiple modules detect the instrument cluster communication failure or indicates a different aspect of telltale data loss.
The most common cause of U1137 (SCP (J1850) Invalid or Missing Data for Telltales) is: Instrument cluster module failure
Typical repair costs for U1137 range from $150 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Critical warning indicators may fail to alert the driver, potentially masking serious mechanical failures. Driver awareness of vehicle status is compromised.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U1137 to identify the root cause.
