Ok can someone explain to me what all the points in the engine bay diag box do?
This would be good tech information to have (as the answers become apparent I will try and update this thread, or construct a PDF with all the information in it )
(JZZ30 Engine Diag box DLC1)
Fp -> Fuel Pump
W -> Check engine light (note that the actual pin is missing great, why toyota leave it out is beyond me)
E1 -> Ground
CC0 -> Exhaust Gas Temperature (The Witzl)
TE1 -> Ground to transmit codes out W
TE2 -> Ground to transmit serial data out VF1
+B -> ECU Switched Battery voltage
VF1 -> Learned Voltage Feedback (TE1 OFF)
Voltage Feedback (TE1 ON, IDL/CTP off)
Serial Data when TE2 is grounded (if OBD with serial)
