Diagnostic procedure

There is communication on the VR-bus as long as there is +54 current. This DTC is generated if response is missing from the relay in question.

The cause of the problem could be power supply, grounding or that bus connection is missing.

• Try replacing the fifth bow latch relay with, for example, the relay for the right front window.
• Activate the relay with the button for the right front window on the center console.
• The latch motor should lock or unlock the fifth bow.
• If the fifth bow locks or unlocks, the problem is likely in the latch relay
