P0Ae5 Fault Code: Understanding The Description And Troubleshooting Steps
The P0AE5 fault code refers to the Hybrid Battery Precharge Contactor Control Circuit RangePerformance.
This code is related to the operation of the System Main Relays (SMRs) in the high-voltage power supply circuit. The SMRs consist of three relays, with one for the negative side and two for the positive side. They are responsible for connecting and disconnecting the high-voltage power supply circuit as requested by the HV control ECU.
During the connection process, SMR1 and SMR3 turn on initially, followed by SMR2. This sequence helps protect the circuit from high-voltage surge current by allowing the limit current to flow through a resistor. When disconnecting, SMR2 and SMR3 turn off in that order.
The HV control ECU checks that the relays have turned off properly to ensure proper operation.
The P0AE5 fault code indicates that there may be a malfunction in the Hybrid Battery Precharge Contactor Control Circuit.
It is important to address this issue promptly to maintain the reliable operation of the high-voltage power supply circuit.
