Re: Not able to drive. P1A15 error.

@Gencis You have several CAN buss errors, but i think the P1A15 is real in your case. The MCU is coded with the VIN number, otherwise it would be somewhat easy to just swap it out with another unit. The function of the little hybrid isolation measurement board seems to be degrading over time in your...

Re: Not able to drive. P1A15 error.

@BlindMoose, All of your errors are CAN buss related. The MCU is not continuously connected to the CAN buss and is throwing 3 codes, 1 for no CAN, 1 for too slow to charge the main capacitor, 1 for too slow to discharge the main capacitor, both of the last 2 are reported by CAN, and if CAN is not wo...

Re: Not able to drive. P1A15 error.

Here's my ideas for something to try. With a known good and fully charged aux battery, measure OCV and when loaded in ACC or ON position too. First clear all the codes with the icarsoft tool, then try to start and see if goes to READY. If not then read the DTCs and write then down. Clear the DTCs ag...

Re: iCarsoft i909 Diagnostic Tool

i think the owner's manual has instructions on how to configure the display for km or mph. It was also posted on the forum by someone but i don't recall which thread, maybe JoeS recalls this? AFAIK, The scannr tool doesn't do this, it is done by the operator in the car.

5V buss on the control board

That 5V relay is held closed constantly during a charging session; the ceramic resistors provide an inrush by-pass circuit to precharge the 3 caps, then when they meet the full condition, the controller commands the 5V to close the relay contacts. The microcontroller chip, IC701, pin 38 drives the b...

Low Voltage Supplies link

@Sandrosan, i found the discussion section about the low voltage power supplies on the control board, http://myimiev.com/forum/viewtopic.php?f=23&t=4079&start=70#p36876 i have to review my notes to see if i hand-sketched the schematic, seems like i would. Can you monitor your 12V output of t...

Re: Gen1 DCDC Converter Troubleshooting and Repair

i would guess that you do need to clear the fault codes--do you know what DTCs were thrown? Do you have an OBDII scann tool to read and clear DTCs?

Re: Troubleshooting and repair for On-board Charger (OBC)

No don't send me any personal messages about the ceramic resistors, there is a 20 message limit and my inbox is full--just post your questions for everyone to see. If i or anyone else can contribute something useful, then we will respond. There are already plenty of discussions about these resistors...
