What Does U1058 Mean?
The control module cannot receive valid transmission gear position (PRNDL) data from the transmission control module over the SCP network. This prevents other modules from knowing the current gear selector position.
Common Causes
35%
Transmission Control Module (TCM/PCM) communication fault or module failure
30%
Faulty transmission range sensor not providing position data to TCM
20%
SCP network wiring issue between TCM and other modules
10%
TCM power or ground circuit problem preventing data transmission
5%
Transmission mechanical issue preventing range sensor operation
Diagnostic Steps
1
Step 1: Use scan tool to monitor transmission range sensor data from TCM/PCM directly
2
Step 2: Check for transmission-related DTCs in the PCM or TCM that might indicate range sensor fault
3
Step 3: Verify TCM/PCM has proper power and ground at all times with multimeter
4
Step 4: Test transmission range sensor operation by moving shifter through all positions while monitoring live data
5
Step 5: Inspect transmission range sensor connector and wiring for damage or corrosion
6
Step 6: Monitor SCP network communication to verify TCM is actively transmitting PRNDL data
Estimated Repair Cost
$150 - $900
Parts + labor, varies by vehicle and location
The control module cannot receive valid transmission gear position (PRNDL) data from the transmission control module over the SCP network. This prevents other modules from knowing the current gear selector position.
The most common cause of U1058 (SCP (J1850) Invalid or Missing Data for Transmission / Transaxle / PRNDL) is: Transmission Control Module (TCM/PCM) communication fault or module failure
Typical repair costs for U1058 range from $150 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May prevent proper transmission operation, affect backup lights, or disable cruise control. Vehicle may not start if system cannot verify Park position.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U1058 to identify the root cause.
