Description

INFOID:0000000004212127

The SMRs (System Main Relay) are the relays that connect or disconnect the high voltage power system in

accordance with commands from the hybrid vehicle control ECU.

The SMR system is composed of three SMRs and one system main resistor. SMRB and SMRG are located on

the HV relay assembly in the battery carrier under the HV battery. SMRP and the system main resistor are

located in the hybrid vehicle converter (DC/DC converter) assembly in the battery carrier.

To connect to the high voltage power system, the vehicle will first turn on SMRP and SMRB to charge the vehi-

cle through the system main resistor. Then, SMRP will be turned off after the SMRG is turned on. To shut off

the high voltage power system, SMRB and SMRG are turned off.

When there is an open in the AMD line or IGCT line, the following DTCs are output:

P0AE6-225 is output first because the time required for diagnosis is the shortest.
