Apply a light coating of dielectric grease to keep moisture out, then reconnect the plug firmly. 2. Validate Power, Ground, and CAN Signal

Here's where things get technical. Using a multimeter, measure the resistance between of your OBD-II diagnostic socket: nissan u1025-00

When any module fails to send or receive the required data from another specific module, the U1025-00 code is triggered. In simple terms, the vehicle's main computer has detected that it cannot properly "talk" to one of its supporting modules.
