On DEC.8, 2021 I posted my question "H-KEY 2020 TOYOTA RAV4 LE EVO ONE WITH T-HARNESS REMOTE STARTER INSTALLED - SYSTEM MALFUNCTION" and got answer. I did what recommand to do, evnen hardwiring CAN HIGH/LOW two wires and use RAV4 CAN connector plugged in ECU, no luck.
My rav4 remote start problem more like this after a few weeks oberservation
Use OEM remote or RFK442 remote, the low fuel yellow light show up after remote started, When going in the car, key in the key cylinder and turne to ON position, press brake, key taking over. The yellow low fuel light disappear, and fuel display needle moving up to level.
After a few times remote starting, when you try another remote starting, the check engine light show up, and screen also shwing "AWD System Malfuntion. 2WD Mode Engaged, Visit you r dealer"
The CHECK ENGINE light was P2067: generic fuel level sensor "B" circuit low. I am wondering that low fuel level sensor B dosen't powered up when remote started, then ECU set the CHECK ENGINE light. I reset it by OBDII, but it keep coming. If no remote starting, RAV4 going normal by the OEM key and no warning light.
Is this could be a communication issue between EVO ONE and RAV4 ? The IGNITION signal from EVO ONE should go power up fuel level sensor B when remote starting, but it doesn't.
Any idea? Could you please look at 2020 RAV4 LE AWD(Canadian version) wiring diagram, see how.
Thanks in advance!
