Hi Peter, In total agreeance with Mickey and kiev. I originally bought a iCarsoft i620, worked OK with the OBDZero App and caniON App, however would'nt work with the Car Scanner App or Hob Drive (it wouldn't allow DTC error resets) so I bit the bullet and bought the OBDLink MX + which functions...

Bonjour Peter, Your English is far better than my French …. ha ,,, “Data Out” is just my terminology for the feedback pulse (Pin 2 WPN) from the pump to the EV-ECU so the ECU can monitor that the pump is working (210-230Hz), if it doesn’t receive this signal then it triggers a P0C73 error...

Hi Peter, I suggest that you purchase a OBD dongle (I use OBDLinkMX+) and download the CarScanner App and it will report DTC Codes, it also allows you to clear some of them. The code I was getting was "Code P0C73 Water pump error”. I haven't done any more work on the old pump, apart from scrape...

Thanks MickeyS for the comment/feedback. After reading many pages on the Forum regarding OBC failure it seems to me that heat has a large part to play in many of the fails, I used to work in an industry where we were told the Air-conditioning was not for our “comfort” it was there for the...

Hi, Finally installed the new coolant pump, topped up the system and purged the air according to the instructions (attached). 1st of all I reset the DTCs P0C73 using the “Car Scanner” App I mis-read Step 2. “Set the electric motor switch to “ON” position” and actually turned it to the “START”...

Thanks for the feedback philsuth, interesting outcome, yours appears to be of a different nature to my fault, however as I have set out below I haven’t installed the new pump yet ….. and yes the P0C73 alarm does come up when charging ..... Status on my P0C73 Fault : So that I could keep...

Hi Don, Wayne Rooney (of AMMMO Group New Zealand) has done an excellent translation of the MiniCab User Manual which may help. and I have also attached a photo of whats under the passenger and drivers seats.

Hi Don 12v aux battery is under rear floor 40B19L or equivalent 30 aph . Wait for a least 2 minutes after turning OFF 'ignition key' before removing terminals to allow data to be written into ECU. Lift floor mat undo 2 screws and lift battery cover. Small Panel on top of dash is for access to...

Thankyou All, I have left the pump on the car and ordered a new one, probably a month before it arrives, will resume the conversation then. In the meantime I have learnt a 'lot' but probably just a 'little' about how the little car works ..... interesting exercise. I must have upset the "pump...

Another thought : Here in Aus we have Mitsubshi PHEV (Plug In Hybrids) using the 10.5kw iMiev battery, I wonder how they keep the OBC cool when charging ? Any PHEV experts out there ??

Thanks kiev, I did try applying power directly to the pump socket, unfortunately with nil result. 12v +ve to pin 3 Vbatt 12 -ve to pin 4 eth 12v =ve to pin 1 (wp) Vbatt also measured voltages on plug with key to Aux position 12v pin 3 with key to On position 14v pin 3 so appears as if Volts are...

Excellent Thanks Joe , more appropriate in the future to be able to search on P0C73 .. thanks bruce

Thanks I'll go with the Penrite .... when I get round to it. I jacked the Van up today , removed back wheel to access pump, and thought I'd try to see if pump worked by just applying Batt and Eth to pins 3 and 4 (no go) .... didn't read your message fully Phil ... or didn't understand it ...

Wow .... Thankyou all I spent time yesterday looking at circuit diagrams (I'm an "old" Tech) like to see how it all operates before I start "operating". I did a 'test' with the ASC switch ( TCL in MiniCab) to see if the pump would turn on , as per instructions on changing the coolant fluid. ie...

Thankyou All, I'm glad I'm not the only one who is experiencing P0C73 codes ... ha ... that information and research is invaluable thankyou. I have only had a cursory look so far , removed the floor panel and had a quick look at wiring, all appears Ok, its been stinking hot here so not too keen...

Thankyou, I'll start today doing some investigating. Reservoir, Fluid , pump working , then from there ... more to come . Quite hot here ... 30c already 0900 am

I've loaded CarScanner App and it will report DTC Codes, the code I'm getting is "Code P0C73 Water pump error (low speed)" ? So I assume this means that my water pump may not be circulating enough fluid to keep the OBC cool ? I have checked the fluid bottle and it does have fluid in it . Next...

Thanks Mickey No haven't tried either of these Apps , however on your advice will now. Thanks for the prompt reply Bruce

Hi, I’m a new member and have been searching thru posts to see if I can find a way to read DTC Codes. I own a MiniCab iMiev 2012 model and have been experiencing the dreaded “! car” error after approx 5 minutes of driving, and around the same time after starting to charge with a EVSE charger...
