4WD Clutch Relay Circuit Failure or Open Circuit
When the Mazda P1825 code is triggered, it usually indicates a failure or open circuit in the 4WD clutch relay. This relay is responsible for the engagement of the 4WD system when the driver attempts to switch the system on. To diagnose this issue, it is important to inspect the wiring and connectors for any defects or loose connections. If any are found, they must be repaired in order to fix the issue.
PCM Has Failed
The Powertrain Control Module (PCM) is responsible for controlling the 4WD system as well as many other systems within the vehicle. If the PCM has failed, it can cause the Mazda P1825 code to be triggered. The only solution to this problem is to replace the PCM or have it reprogrammed to the latest software version.

If any of the hoses become clogged, it can cause the system to become malfunctioning and trigger the code. In order to fix this issue, the vacuum hoses must be cleaned to remove any clogs or blockages.
Conclusion
The Mazda P1825 code can be caused by a variety of issues, ranging from a failure or open circuit in the 4WD clutch relay to a faulty Powertrain Control Module or clogged vacuum hoses.
