Toyota Prius High Voltage System Fault Technical Refere Technical reference. this toyota prius had malfunction warning lights illuminated and two faults relating to the high voltage system stored. p3000 battery control system. intermittently the vehicle would not enter “ready mode” and the high voltage system would remain inactive as the high voltage contactors (system main relay smr 1, 2 and 3. Touring. for the gen 2, the p0a0d code signifies one of the hv safety interlocks is triggered. there are 2 interlocks, hopefully the info is the same for gen 3. the orange interlock on the hv battery (designated as "#2 interlock switch" in the manual). this interlock is made up when the third step of the plug installation procedure is completed.
Toyota Prius High Voltage System Fault Technical Refere Snap on diagnostics has released a technical reference for a toyota prius high voltage system fault. this toyota prius had malfunction warning lights illuminated and two faults relating to the high voltage system stored. module. code. hybrid control module. p3000 battery control system. hv battery control module. Volt fault brings prius to a holt. this toyota prius had malfunction warning lights illuminated and two faults relating to the high voltage system stored. module. code. hybrid control module. p3000 battery control system. hv battery control module. p0afa hybrid battery system voltage low. intermittently the vehicle would not enter “ready mode. Strawbrad said: ↑. there is a high voltage connection between the battery and car body. it is through the battery computer. i know it is on the negative side of the sensing wire harness. i think it is the most negative sensing wire. i have measured this. it is easy to bleed off the voltage with a volt meter. When an isolation fault is detected, the trouble code p0aa6 (hybrid battery voltage system isolation fault) will be stored. also, an information code 526 will also set at the same time. once the driver tries to restart the car, the hv ecu will perform testing to find out which section of the high voltage system is shorted to ground.
