CS75 PLUS power tailgate not responding: check protection and initialisation first

CS75 PLUS power tailgate not responding: check protection and initialisation first

If a CS75 PLUS power tailgate reverses partway through closing or stops responding after repeated operation, do not immediately order a pair of powered struts. Establish whether there was an obstruction, whether it had just been opened and closed repeatedly, and whether power had been disconnected or the controller replaced. This helps distinguish a state requiring recovery from an actual component fault.

Reversal after an obstruction is a documented response

The CS75PLUS NEW handbook on the Russia website states that an obstacle or substantial resistance during opening or closing triggers the anti-pinch function. The tailgate reverses for a distance and then stops. [Factory tailgate explanation][S17]

Reversal alone is therefore insufficient evidence of strut failure. First establish whether there was an obstacle and adequate movement space, rather than repeatedly pressing the switch until the tailgate closes. The handbook also stresses that anti-pinch is only an aid. It cannot replace attention to people and obstacles; do not test it with fingers.

Repeated operation can trigger a protective state

The handbook describes another condition: more than 10 consecutive opening and closing operations within a certain period may activate protection against repeated operation. The tailgate stops responding to controls and exits this state after approximately 10 seconds. [Repeated-operation protection][S17]

These figures explain the conditions described for this handbook version; they are not an instruction to repeat operations as a test. A record saying only that the tailgate does not move should include what happened beforehand, so temporary non-response during protection does not automatically become a controller or strut order.

Initialisation differs after power interruption and controller replacement

The handbook states that if the tailgate is open when the battery is reconnected, it must be fully closed to complete initialisation. If it is already closed, that action is unnecessary. After power-tailgate ECU replacement, opening-position learning must also be initialised by an authorised service centre. [Initialisation guidance][S17]

Changes after power interruption and work following controller replacement should be checked against the relevant requirements. Installing a new part does not establish completed initialisation. Equally, a state that has not yet been restored correctly is insufficient evidence that the new part is defective.

Verification and parts enquiry

This article is limited to power-tailgate-equipped configurations in the Apr 2025 CS75PLUS NEW handbook on the Russia website. No public data were available for detailed fault diagnosis, left/right struts, permitted component-level repairs, force values, OE numbers or interchangeability. The handbook prohibits dismantling powered struts because their internal high-pressure springs may cause injury. Repair requirements need separate verification. [To be verified] Compatibility and interchangeability must be checked using the VIN and local factory parts catalogue.

For tailgate parts after damage and repair scope are established, use the parts enquiry page.
