DTC Descriptor
DTC P06B1
- Sensor Positive Voltage Circuit 1 Low Voltage

DTC P06B2
- Sensor Positive Voltage Circuit 1 High Voltage

DTC P06B4
- Sensor Positive Voltage Circuit 2 Low Voltage

DTC P06B5
- Sensor Positive Voltage Circuit 2 High Voltage

Circuit/System Description

The drive motor generator power inverter module contains two motor control modules and a hybrid powertrain control module. The motor control modules share an internal 15 V reference power supply in order to operate the drive motor sensors processors. This fault is handled inside the drive motor generator power inverter module and no external circuits are involved. The motor control modules and the hybrid powertrain control module are part the drive motor power inverter module and are not serviced separately.

Conditions for Running the DTC

* The ignition is ON.
* The system voltage is 8-18 V.

Conditions for Setting the DTC

P06B1 or P06B4

The reference voltage is less than 12 V for 1 second.

P06B2 or P06B5

The reference voltage is greater than 18 V for 1 second.

Action Taken When the DTC Sets

* DTCs P06B1, P06B2, P06B4 and P06B5 are Type B DTCs.
* The drive motor generator power inverter module commands the battery energy control module to open the high voltage contactor relays.

Conditions for Clearing the DTC

DTCs P06B1, P06B2, P06B4 and P06B5 are Type B DTCs.
