What Does B2310 Mean?
This diagnostic trouble code indicates that the Body Control Module (BCM) has detected a fault in the driver's side power mirror memory position system. The memory feature, which stores and recalls preferred mirror positions linked to driver seat settings or key fob identification, has failed to save, retrieve, or execute the stored position correctly. This suggests a communication error, mechanical binding, actuator failure, or corrupted memory data within the mirror adjustment system.
Common Causes
35%
Faulty mirror actuator motor or position sensor providing incorrect feedback to BCM
25%
Corrupted memory data in BCM or memory module requiring reprogramming or reset
20%
Wiring harness damage, connector corrosion, or poor ground connection to driver mirror
15%
Mechanical binding or obstruction preventing mirror from reaching stored position
5%
Low voltage or battery issues during memory recall operation
Diagnostic Steps
1
Step 1: Manually operate the driver mirror adjustment controls in all directions (up, down, left, right) and verify smooth operation without binding, unusual noise, or hesitation. Attempt to store and recall a memory position using the memory buttons to determine if function is completely non-operational or intermittent.
2
Step 2: Using a digital multimeter, test for proper voltage supply (typically 12V) and ground at the driver mirror connector with key on. Check for voltage changes on the motor control wires when adjusting the mirror position to confirm BCM is sending commands.
3
Step 3: Inspect the driver door wiring harness for damage, pinching, or wear at flex points between door and body. Remove mirror connector and inspect pins for corrosion, bent terminals, or moisture intrusion. Clean and apply dielectric grease if corrosion is present.
4
Step 4: Access BCM configuration using advanced scan tool functions and attempt to clear memory settings and re-initialize mirror memory system. Test memory store and recall functions after reset to verify if corrupted data was the issue.
5
Step 5: If all electrical tests pass, remove mirror assembly and inspect internal actuator motors and position sensors for mechanical wear, broken gears, or failed potentiometers. Replace mirror assembly if internal components are damaged.
6
Step 6: After repairs, clear the DTC, program new memory positions, and cycle through all memory recalls multiple times to confirm proper operation and verify code does not return.

The most common cause of B2310 (Mirror Driver Memory Position Error) is: Faulty mirror actuator motor or position sensor providing incorrect feedback to BCM
Typical repair costs for B2310 range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This code does not affect vehicle safety or driveability and the vehicle is safe to operate normally. The only impact is loss of convenience features related to automatic mirror positioning for different drivers, requiring manual adjustment of mirrors.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2310 to identify the root cause.
