In this video i show you how to read and analyze wiring diagram on nissan. i explain how to find the components, wire colors, pin numbers, connector details. Hold the paper clip on the bracket to ground it. hold it there. the tpms light will light up for 5 seconds, go off for 5 seconds, then start flashing a 2 digit code. the longer flashes are the first digit, the shorter flashes are the second digit. to stop the diagnostic, just release the paper clip from ground.
The wire colors are never shown on the circuit diagrams. you have to go by the connector number and pin number. then, refer to the connector listings which are in the pages after the circuit diagrams. on the connector listings they have the wire colors and a drawing of the connector. Black: ground or chassis connection. yellow: constant power, even when the ignition is off. blue: headlight circuit or other exterior lighting. green: ignition controlled circuit (power only when the key is on) white: auxiliary circuits or instrument cluster lighting. brown: rear lighting (taillights, brake lights, etc.). By decoding the purpose of these wires, technicians can diagnose and troubleshoot electrical issues more effectively. the communication wires in nissan wiring diagrams are typically color coded for easy identification. common colors used for communication wires include green, blue, yellow, and black. Pin 47 mass air flow sensor input (0 5v signal) pin 48 mass air flow sensor ground. pin 49 sensor power supply output 5v. maf harness wires: signal wire orange (shielded) ground white. power supply orange (no shield) hope that helps! let us know how it goes!.

The rf door trigger is red blue in pin 12. the lr door trigger is red yellow in pin 48. the rr door trigger is red white or gray in pin 13. use all four wires and diode isolate each. dome supervision blue bcm to right of column, pin 63. notes: the blue wire is for the dome lights and puddle lights. I have a wiring diagram for the accessory connectors for a 2023 (should be the same as 2022) frontier. the # 3 and #6 pins don't appear on either sides connector for the vehicle side of the harness, and there are more pins used on the driver side than the passenger side of the harnesses. i hope this is helpful.
