DTC Descriptors

DTC P0697

-
5V Reference 3 Circuit

Circuit/System Description

The generator control module also called the starter generator control module is comprised of the following three control modules; the hybrid powertrain control module, 14 volt power module and the drive motor control module. These three control modules are non serviceable and are part of the generator control module.

The hybrid powertrain control module has three internal 5 V reference circuits. Each internal reference circuit provides a 5 V reference for one or more sensors. A short to ground or short to voltage on one external 5 V reference circuit can affect all components connected to the same internal 5 V reference circuit.

Conditions for Running the DTC

* Ignition is on.

* Ignition voltage is greater than 10 V.

Conditions for Setting the DTC

The hybrid powertrain control module detects a voltage out of range on the 5 V reference 3 circuit for greater than 5 seconds.

Action Taken When the DTC Sets

DTC P0697 is a Type B DTC.

Conditions for Clearing the DTC

DTC P0697 is a Type B DTC.

Diagnostic Aids

The 5 V reference 3 circuit provides 5 V to internal circuitry contained in the generator control module.
