Hi guys and girls. I bought myself a beautiful hybrid - 2007 GS450h President with radar option. 180k km on it, with full service history. The car was sitting on the market parking lot for a while (maybe up to 8 months). Well, week after the purchase I went on a highway and floored it. First I accelerated to 140 km/h, took my leg off the gas pedal and then I pushed the PWR hybrid button and on 120 km/h I floored the gas pedal again - but this time after few seconds there was a mild bang, smoke under the hood, dashboard showed all of its lights and car shut down. I now have the car in my garage. First, we found out that the fuse before battery pack was done. Then we found out that the inverter was totally burned (we opened it, it was ashes). I bought a new fuse and a used inverter (got it cheap, right-hand drive model - just to test). We tested MG1 and MG2 with megger (ohm meter?), just to make sure that they are still there When I replaced the fuse and inverter I managed to get the car into Ready mode. But ICE wouldnt start, 10 seconds after Ready mode appeared I got hybrid battery error on my dashboard with VSC and others. It appeared that the hybrid battery was totally empty (soc 0%, voltages around 10 for a 2module pack). I thought that maybe when the inverter failed the battery was sucked dry when there was the fire inside the inverter until connections melted there (because maybe no control mechanism was working at the time of malfunction) Now, i disassembled the battery pack and charged (cycled couple of them) all individual batteries one by one. I assembled everything back together, battery soc is 60% voltages are nice. But now the car won't go to the ready mode. I have these codes currently: Under Hybrid control: P0A1B Drive Motor "A" Control Module U0110 Lost Communication with Drive Motor control Module "A" Under ABS/VSC,TRC: C1259 HV Control System Regenerative Malfunction C1310 HV System Malfunction I found out that the last two codes should be just informative messages and the problem should be the first one P0A1B. And the P0A1B is directing the problem towards inverter, based on my google skill (but not much information about this code out there :/ ) Now, what should I do next, getting quite hopeless here... It is possible that the right-hand drive used inverter is also bad, but don't forget that I had the car on Ready mode for a short time (but at that time the hybrid battery was totally empty) Also the 12V battery is changed, good and full. Hope you guys have some good ideas.
