DIAGNOSTIC TECH Figure 5 - Connectors of interest Figure 8 - Five-way coolant valve stripped gear Figure 6 - Tesla SI - Connector location guide Figure 9 - High voltage information Figure 7 - Five-way coolant valve calibration failure Figure 10 - Model 3 with heat pump I checked the harness connector, and all looked fine, so I ordered a new actuator and replaced it. After replacement, I performed a cooling system bleed procedure where the fiveway valve went through a calibration routine resulting in the error message disappearing. I decided to do a post-mortem onhttp://www.VehicleServicePros.com
