DRL Control Module Inspection

WARNING: This page is about a different car, the 2004 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.

Measure the voltage at the DRL control module terminals as indicated below.
Disconnect the DRL control module connector before inspecting for continuity at terminal 1E.
- If not as specified, inspect the parts listed under "Action."
- If the parts and wiring harnesses are okay but the system still does not work properly, replace the DRL control module.
