Function test
Check the function of remote keyless entry (RKE) by locking or unlocking the car using the remote control.
The receiver functions as a receiver for both the remote control and the keyless functions in the vehicle.
Note! Depending on which customer settings are made, it cannot be guaranteed that the same doors unlock on different vehicles. To reprogram the customer settings, select cancel. To retrieve fault-tracing faster select Pause and save a bookmark.
Is the function OK?
Yes - Fault-tracing information
No - Checking the power supply
-------------------------------------------------
Fault-tracing information
The keyless vehicle module (KVM) has previously registered a fault but the fault no longer exists. The diagnostic trouble code (DTC) was probably caused by an intermittent fault. If the fault persists, fault-tracing according to this diagnostic trouble code (DTC) must be carried out despite no fault symptoms being found. The fault is evaluated depending on how it occurs.
You can choose to view the information again or exit the fault-tracing.
Do you want to view the information again?
Yes - Function test
No - No Fault Found
-------------------------------------------------
Checking the power supply
- Ignition off.
Check the wiring for the power supply and ground between remote keyless entry (RKE) and the central electronic module (CEM). Check for an open-circuit. Check for a short-circuit to supply voltage. Check for a short-circuit to ground.
The voltage must be 12 V when the ignition is off.
Remedy as necessary.

Was a fault detected?
Yes - Verification
No - Checking communication
-------------------------------------------------
Checking communication
- Reconnect cables and switches
- Ignition on.
Check communication with remote keyless entry (RKE) by clicking the VCT2000 symbol.
Note! The results of the communication check display what the control modules determine as faulty. Fault-trace the cable if the result of the test is that there is an open-circuit, a short-circuit to supply voltage or a short-circuit to ground in the signal cable to remote keyless entry (RKE). Check the type of fault displayed.
Remedy as necessary.
Was a fault detected?
Yes - Verification
No - Replacing the control module
-------------------------------------------------
Replacing the control module
The fault is probably an internal fault in remote keyless entry (RKE) as no other faults were detected. The module should be replaced in this case.

Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off
- Reinstall the connectors, components etc.
- Ignition on.
Check the function of remote keyless entry (RKE) by checking the communication with the receiver. Click the VCT2000 symbol to begin.
The result should be OK.
