Just an update on this - might help someone in the future. I had the p0a93 code and check hybrid system error. Was fairly sure it was the inverter cooling pump . After removing the pump, it appears that some of the internal electrics on the pump were heavily coroded. I replaced it with this 'similar' pump used in various Lexus and Toyota hybrids (but still reasonability priced) https://www.auto-doc.ie/ackojap/13701334 I have clocked up about 1400km in last month without issue - so fingers crossed....

I know it’s a few years ago but any chance you remember where you got the pump

I have the basic paid version and it has "clear DTC" options once you scan the ECU. Obviously the error will come back until the underlying problem is fixed - in my case, the water pump for the inverter replacement

I am currently also facing the 'Check Hybrid System' . In my case, I am using a cheapo OBD2 code reader and "EODB-Facile' and Dr Prius apps. Both work fine on my car. I can clear the "Check Hybrid" and Dr Prius can monitor all the individual cells in the hybrid battery. I'm waiting on a new Inverter cooling pump so won;t know for sure it that fixes it for me for a few weeks.

Hi I have a 2008 GS450h that is giving the 'check hybrid system' and error code p0a93 I think it is the pump failure as the wiring, fuses and connectors are in reasonable shape. There is coolant in the resevoir and I dont see any movement in fluid when the engine is running. Car will run ok for 10-15mins and then throw the check engine.... The Lexus dealer pricing for the replacement pump is nearly €600 (Dublin, Ireland) - and thats just for the part. G9040-30010 Is there any other parts that might fit - or cheaper parts suppliers. Thanks Dan

Its usually handy when you have slowed down and want to hit resume... Most other cars I've had in the past had been like this. Wife has a Rav4 which does have it. Saw it the owners manual - but it might be just for the radar version....

Hi I have a 2008 GS450h. It notice that when cruise control is set that there does not seem to be a display of what the currently set speed is ? Cruise works fine, the "cruise" message comes on and off as it should. But I thought I should see a speed display on dash
