If your electric step no longer extends or retracts, there may be several reasons for this. In many cases, the cause can be narrowed down with simple tests and minor problems can be rectified directly.
Here are a few reasons why the step is no longer working properly:
Soiling
Deposits such as dirt, salt or dust can impair the mobility of the step or cause contact or door switches to no longer respond reliably.Defective fuse
If the fuse for the step is damaged, it will no longer be supplied with power correctly. This can prevent automatic retraction when the motor is started.Mechanical defect
Unusual noises such as a repeated "clack-clack" may indicate a defect in the end switch, motor, drive pinion or other mechanical components.
With this step-by-step guide, you can quickly narrow down the most common causes.
Step-by-step check
1. Check buffer position
Battery: Is the leisure battery charged?
Battery disconnect switch on the EBL: Is the battery disconnect switch on the EBL switched on?
Check and replace fuse: Check the fuse of the step on the EBL, which is located under the passenger seat or behind the driver's seat, depending on the vehicle. Make sure that the 25 A fuse is undamaged and replace it if necessary.
The most common causes of failure are a lack of voltage or a blown fuse.
Tip: Always carry a suitable spare fuse with you when travelling - this way, small problems can be rectified quickly.Important: A defective fuse can result in the step not retracting automatically when the engine is started.
2. Ignition & safety
Some vehicles automatically retract the step when the ignition is switched on.
If it does not respond at all, this may indicate an electrical problem in the system.
3. Check shim situation
A faulty door contact often prevents the step from being released.
Open/close the door completely.
Check the door contact switch for dirt or blockages. Thoroughly remove dirt, dust and deposits from the step.
4. Clean the mechanics
Dirt, salt or dust can block the mechanism.
Clean the step and lubricate moving parts carefully (e.g. Silicone spray). Do not use highly adhesive grease, as this attracts additional dirt and can block the mechanism in the long term.
Assess the mechanical defect: If you hear a recurring "clack-clack" sound when operating the switch, this may indicate a defective end switch, a problem with the motor or the mechanics. In this case, do not keep the switch pressed permanently as this may cause the fuse to blow again.
Tip: If the clicking noise occurs continuously, it may be advisable to pull the fuse as soon as the step is fully retracted or extended to avoid consequential damage.
5. Test switch & automatic function
Operate the step switch manually.
Does it work in one position but not in another? Check the reactions carefully.
Ensure emergency assistance on the road
If the step cannot be fully retracted and cannot be repaired immediately, secure it temporarily.
Use a safety bracket or sturdy cable ties, for example, to secure the step firmly in the retracted or extended position.
Before continuing your journey, check that the secured step is firmly in place and cannot come loose during the journey. An unsecured step poses a safety risk.
Small problems can often be solved simply by cleaning and checking the fuse. If there is no improvement after all these steps, there may be a faulty motor, cable break or control unit error - then contact your Carado dealer and service partner.
