DTC P0AE6-225: Hybrid Battery Precharge Contactor Control Circuit Low; DTC P0AE7-224: Hybrid Battery Precharge Contactor Control Circuit High: Description
WARNING: This page is about a different variant/trim than selected.
The SMRs (System Main Relays) are the relays that connect or disconnect the high voltage power system in accordance with commands from the hybrid vehicle control ECU.
There are 3 SMRs and 1 precharge resistor. SMRB, SMRP, SMRG, and the precharge resistor are located in the HV battery junction block assembly in the HV battery pack.
To connect to the high voltage power system, the vehicle will first turn on SMRP and SMRB to charge the vehicle through the system main resistor. Then, SMRP will be turned off after SMRG is turned on. To shut off the high voltage power system, SMRB and SMRG are turned off.
