Under the passenger seat on a hybrid is the battery cooling fan, relays, battery ECU and one end of the hybrid battery assy. The aux 12v battery on mine is under the drivers seat the original fitted by CampervanCo was a Optima Red Top Starting only 44Ah 730A which was a mystery to me because the Hybrid does not need a high Ampage battery as the hybrid battery starts the engine, but it does need a high capacity. I managed to squeeze in a slightly larger battery Exide AGM 62Ah, 680A part number EK620. L02 size 242 x 175 x 190. There is quite a high drain on the battery when parked up for any length of time from various ecu's alarm radio central locking, and once the battery has been discharged it won't be able to supply enough power for the hybrid ecu to start the engine. on turning on the ignition I have found the voltage can drop by nearly 2 v.

Who did your conversion?

I have another picture for the location of the 2-way compressor control amplifier and it is to the side of the blower, possibly get access by removing the two passenger storage bins and the trim panel. From the manual, which I have nearly finished translating, It outputs a compressor drive signal to the A/C inverter according to the operation enable signal from the HV control computer and the signal from the dual automatic air conditioning computer. In addition, when belt drive is used, it inputs a variable capacity signal from the dual automatic air conditioning computer to control the compressor control valve. The computer is built into the control panel. There is a self test that can be performed on the panel; While simultaneously pressing the "AUTO" switch and the "Inside/Outside Air Change" switch on the control panel, change the IG switch from the OFF position to the engine start position. When panel diagnosis is activated, an indicator check is performed automatically. Check that all indicators and setting display sections light up and go out four times at 1 second intervals. Once the indicator check is complete, a sensor check will be performed automatically. Press the “inside/outside air change” switch to perform an actuator check. After the actuator check is completed, press the “AUTO” switch to perform a sensor check again. The result of the sensor check is displayed on the set temperature display. To end the panel diagnosis, press the “OFF” switch. [Electronic Technical Manual] AC fault codes.pdf

Try Amazon.us I got a 110v air fryer from them, free postage as well!

Hi, is the 12v battery good? monitor the voltage when the ignition is turned on if it drops below 10-11 v this will affect the ECU's, they won't play. The HV battery cells are all connected in series so only as good as the weakest cell, just like a chain. If there was a problem with block 10 you would get code P3020 P3004 depends on what the sub code is: -131 When the EV battery fuse is blown, the service plug grip is dislodged, or the high voltage wiring resistance is broken. -132 Inverter voltage sensor abnormality or high voltage wiring resistance increase -133 Abnormal signal received from battery computer ASSY -268 Inverter voltage signal is out of sync with HV battery voltage

Are you sure it is P1325 as inverter faults are P3123-xxx, if so, you need to find the sub code (-xxx) to identify the part in the inverter or wiring to the ECU's.

Because of its small capacity of 44Ah, it is important to keep it charged up if not regularly using the vehicle, at least once a week. I plug in the AC hook up every week ,with a dehumidifier running inside as well when not using the van after the roads have been gritted or a foot of snow as we have now.

Check with your conversion company to see what battery they installed. It has to be low enough to clear the underside of the seat, I guess it is raised up slightly with a swivel base. If it is a CampervanCo conversion they installed a Red top AGM battery in mine.

You don't need to power down the HV to clean the Hybrid ECU. From the description of what is happening and the lights it looks like a HV battery issue, one bad block is all it takes. If the capacity of the block reduces, it will charge up quicker then discharges quicker than the rest. You also have a HV battery temp warning on and a motor generator temp warning on as well, is the HV battery cooling fan on max. Check behind the front passenger seat forward trim in the footwell for water, the HV battery ECU connector is there. You need to get a code reader to find out what is going on.

Finger trouble!! just replace the bad pair of cells. A few hybrid battery repair companies around that can test and repair your battery.

Hi, I presume it is, a better performing with smarter charging than the gen 2. You have to replace all the modules within the battery. The battery is only as good as the weakest cell, so you could

A power seat mechanism and side lift-up mechanism are available on the left side of the captain's seat as a manufacturer option. Approx dimensions; Ground to floor - 52cm Rear door lower opening trim to top of rear opening - 120cm As Rojie has already mentioned the tail gate hangs down a bit when open

If you are removing the engine ECU to clean the contacts and harness connectors, the hybrid ECU is the box forward and at right angles to it. While you are in there, it would be worth cleaning those contacts /connectors as well.

They are on facebook which gives you some idea of the different work they do plus reviews.
