This is a connector on the head unit that feeds in the vehicle speed. Note this is for a 2.4 10 series hybrid , your wiring will probably be different.

Thanks, but I have adapted a script from another menu .html file and now the wiring menu works. Sounds a bit dodgy buying from a Russian in crypto 🤔

C1310 is a traction control malfunction, this normally occurs when there is a hybrid issue the computer stops regenerative braking and stability control via the rear motor. P3009 When the insulation resistance between the high voltage circuit and the body is below the standard value. 10M ohm. Defective parts listed include the inverter and all the cables that might have been disturbed during the sensor change. How ever, suggest clearing code switch off ignition then on again, not start, and after 2 mins check codes. P3009 relates to the main battery, HV, cables within the battery assy, which I guess you did not disturb apart from the service grip. It could be the main battery cables at the inverter which you disconnected. Has the sensor replacement fixed that issue?

Power output sockets are 110v ac 1500w max, american style 2 pin plug. To use engine must be on, READY light on, 110v select push button, to the right of the steering wheel, push in and the advisory light in the switch will light. Use a continental adaptor to charge phone, laptop, air fryer, induction hob etc with regard to max power and voltage applicable.

Hi Chris I have this CD but would not install onto my windows 11 computer, so I just had to copy the files manually and open index2.html. I also tried installing it under windows XP, that didn't work either. I have translated most of the disc but some reason the wiring diagram menu doesn't work due to a Javascript function that is missing, I think. "function FC(WO)" Can you search your disc to see if is present. Most of the .gif images in the description section have a .pdf version as well but I can't get this to load instead. Next is to find a program that will open, translate scanned .pdf files then save automatically!

Yes, unfortunately. Secondary pulley rotation speed sensor that detects the output shaft rotation speed is placed on the secondary pulley shaft (reduction drive gear), which is NOUT. This the top one on the diagram to the rear of the square shape bit of the gearbox. rab0711c.pdf

DTC P0500 is a vehicle speed fault, not a gearbox speed sensor issue. Gearbox speed sensor faults are DTC P1820 and P1825. The speed signal comes from the wheel speed sensors to the skid control computer then to the combination meter, from there is a wire to the engine ECU, head unit, power amplifier and cruise control. Possibly in that line also is a chip to convert kph to mph. As the issue occured after installing your new head unit I would look at the speed signal wire to that. Grey connector, pin 3, violet colour

What about the cruise control you fitted, has that done something to the speed signal?

Hi There is no alternator on the hybrid, the aux battery is charged from the inverter / converter, 13.6v seems reasonable if the aux battery is fully charged. You have replaced the aux battery so the terminals should be good, check the earth straps, battery to body and body to engine. Anything wrong with the hybrid system would throw up codes. Could be the engine ECU, clutching at straws now without codes.

P3101-548 Abnormal signal received from engine control computer (CVT system abnormality) The hybrid vehicle computer performs fail-safe control based on an abnormality signal from the engine control computer (when the engine control computer detects an abnormality that may affect THS control). This points to the speed sensor on the gearbox as the signal goes to the engine ECU, then the hybrid ECU goes into limp mode. P1825 is the speed sensor circuit NOUT (speed out), wiring or the sensor, there are no other connectors in the circuit. Did you check the NIN circuit to ensure you have the correct connector and pins? Just to rule out the engine ECU being faulty!!

when driving

Do you have the data page for the HYBRID CONTROL ECU which will show gearbox speeds

As above, 12v is very important for the ecu's on starting. The READY light when on means it is ready to drive, flashing - it is starting up from total power off state. You don't need to hold the key in the start position, it is beneficial when the battery is low is to turn the key from off to start in one go. Issues could be the inverter or the combined power steering / gearbox oil pumps are driven by an a/c motor, has failed. Need to get the codes / sub codes read

do you have any sub codes for P3120- xxxx as this will narrow down the fault

You could double check you have the correct pins on the connector, I have had this issue, by checking the good speed sensor in the transmission. Same connector as above but check between pins 12 and 19; Using a Toyota electrical tester, check the resistance between the engine control computer's vehicle side connector D12 (NIN+) terminal and D19 (NIN-) terminal. Reference value: 560-680Ω (20°C) If you get this resistance but nothing on the NOUT pins then you know it is either the sensor or wiring. I had a look at my engine to see if I could see the sensors, but no luck with the inverter cables, hoses and other cables in the way.
