Introduction
This guide provides information on how to access and troubleshoot the courtesy light switch in the rear door of a Prado, specifically addressing situations where the courtesy lights fail to activate when the rear door is opened. The issue can also affect the central locking system, causing the doors to relock if only the rear door is opened.
Problem
The courtesy lights do not activate when the rear door is opened, even though they function correctly with other doors. This may also be accompanied by the central locking system relocking the vehicle if only the rear door is opened.
Solution
The courtesy light switch for the rear door is integrated within the door latch mechanism itself. Accessing the switch requires disassembling the door panel and potentially the latch mechanism.
Possible causes include:
- Faulty switch: The switch within the latch mechanism may have failed.
- Wiring issue: Broken or damaged wires where they pass from the door to the vehicle body can interrupt the signal.
