Screw

4‑way valve coil

4‑way valve body

Install and tighten the screw to fix the 4‑way valve coil.

Route the 4‑way valve coil harness towards the appropriate PCB.

Connect the 4-way valve connector to the appropriate PCB.

WARNING

When reconnecting a connector to the PCB, make sure to connect it on the correct
location and do NOT apply force, as this may damage the connector or connector
pins of the PCB.

Fix the 4‑way valve coil harness using new tie straps.

Is the problem solved?

Action
