What Does U1173 Mean?
This is a companion code to U1172 indicating continued or intermittent loss of communication with the remote button control system. Multiple codes suggest a persistent network communication fault rather than a temporary glitch.
Common Causes
40%
Failing clockspring with intermittent circuit breaks during steering operation
25%
Intermittent connector issue at steering wheel control module
20%
Intermittent open circuit in remote control wiring harness
10%
Remote control module internal intermittent fault
5%
Loose mounting or vibration causing intermittent connection loss
Diagnostic Steps
1
Step 1: Perform steering wheel rotation test while monitoring control module communication on scan tool
2
Step 2: Wiggle and flex steering column connectors while watching for communication dropouts
3
Step 3: Measure voltage drop across clockspring circuit under load to identify high resistance
4
Step 4: Inspect clockspring for visible damage, wear, or broken ribbon cables
5
Step 5: Use oscilloscope to monitor SCP bus signals during steering wheel movement for signal degradation
Estimated Repair Cost
$200 - $700
Parts + labor, varies by vehicle and location
This is a companion code to U1172 indicating continued or intermittent loss of communication with the remote button control system. Multiple codes suggest a persistent network communication fault rather than a temporary glitch.
The most common cause of U1173 (SCP (J1850) Invalid or Missing Data for Remote Button Control) is: Failing clockspring with intermittent circuit breaks during steering operation
Typical repair costs for U1173 range from $200 to $700, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Potential safety concern if clockspring is failing, as it may affect airbag and horn circuits. Recommend prompt diagnosis and repair.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U1173 to identify the root cause.
