Code P1B06 Description

The high voltage interlock circuit is utilized to verify high voltage component integrity. High voltage interlock circuit is a circuit loop that passes through certain high voltage components. High voltage interlock circuit is used to determine if access to high voltage components is being attempted. The opening of these high voltage components causes the high voltage interlock circuit to open. The battery energy control module sources about 12 mA of current on the 5V high voltage interlock circuit loop. The battery energy control module monitors both the high voltage interlock source current circuit and the high voltage interlock return current circuit in order to detect circuit faults. Both motor control modules monitor the circuit for current in order to detect an open condition. When the battery energy control module and/or the motor control modules sense conditions such as a loss of high voltage interlock circuit current, the high voltage contactor relays are commanded open by the hybrid powertrain control module.
