What Does U1195 Mean?
The mirror control module is not communicating properly over the SCP (Standard Corporate Protocol) J1850 network bus. Either the module is not sending required data, or other modules cannot receive mirror position/adjustment information.
Common Causes
35%
Driver or passenger door module (DDM/PDM) communication failure or internal fault
30%
Damaged or corroded wiring/connectors in door harness or hinge area
20%
SCP network bus fault affecting multiple modules
15%
Failed mirror control switch or mirror motor module
Diagnostic Steps
1
Step 1: Monitor live data stream to identify which module is not transmitting mirror data on the SCP bus
2
Step 2: Inspect door wiring harness and connectors, especially at hinge flex points, for damage or corrosion
3
Step 3: Test door module power and ground circuits with multimeter (B+ and chassis ground)
4
Step 4: Check SCP bus voltage (should be approximately 0-7V square wave) at door module connector
5
Step 5: Replace door module if power/ground/bus signals are present but module still not communicating
Estimated Repair Cost
$150 - $600
Parts + labor, varies by vehicle and location
The mirror control module is not communicating properly over the SCP (Standard Corporate Protocol) J1850 network bus. Either the module is not sending required data, or other modules cannot receive mirror position/adjustment information.
The most common cause of U1195 (SCP (J1850) Invalid or Missing Data for Mirrors) is: Driver or passenger door module (DDM/PDM) communication failure or internal fault
Typical repair costs for U1195 range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
No direct safety impact. Mirror adjustment functionality may be limited or inoperative, which could affect visibility during lane changes.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U1195 to identify the root cause.
