B2600

What does B2600 mean?

B-code B2600 means "Double Locking Door Motor Frozen". It is a generic OBD-II diagnostic trouble code (DTC) in the body electronics. The double locking door motor frozen is mechanically or electronically stuck and cannot move to the commanded position. This code can be monitored, but service is recommended to prevent escalation. This code applies to OBD-II compliant electric and hybrid vehicles.

Possible Causes

• Mechanical obstruction preventing movement to the commanded position
• Actuator motor failure or binding due to wear
• Ice or debris accumulation blocking mechanical travel
• Faulty position feedback sensor incorrectly reporting stuck position

Recommended Actions

1. 1 Note the alert and schedule a diagnostic appointment when convenient
2. 2 Scan for all DTCs with an OBD-II scanner — note any related codes stored alongside B2600
3. 3 Inspect the mechanical component for physical obstruction, ice, or debris
4. 4 Manually operate (if safe) to check for binding or unusual resistance
5. 5 Clear the DTC, road-test the vehicle, and re-scan to confirm whether the fault returns
6. 6 If the fault persists after inspection and clearing, consult an EV-certified technician for component replacement
