This page is dedicated to use of Toyota inverters (Lexus / Camary / Gen3 Prius / Auris / Yaris) unmodified via the serial protocol (REQ, CLK, HTM, MTH). This page also contains wiring and connector information for the various models of Toyota Inverters.
Toyota Protocol
- REQ Request line from hybrid controller to Inverter
- CLK Clock signal from hybrid controller to Inverter (Constant 500KHz)
- HTM Hybrid controller to Inverter data frame
- MTH Inverter to Hybrid controller data frame
Bus Transfer Sequence starts with the REQ line changing state
