DTC Type Reference

Powertrain Diagnostic Trouble Code (DTC) Type Definitions (See: Diagnostic Trouble Code Descriptions/Powertrain Diagnostic Trouble Code

(DTC) Type Definitions)

Circuit/System Verification

1. Clear the DTC information.

2. Ignition OFF for 1 minute.

3. Ignition ON, start and drive the vehicle.

4. Retest for DTCs P061A and P061B.

Circuit/System Testing

P061A

Program the PIM with the latest software version and recheck for DTCs.

If the DTC resets after programming or if the PIM already contains the latest software version, replace the PIM.

P061B

1. DTC P061B may set when Hybrid Battery power output is limited. A reduced hybrid battery power condition is most noticeable during high

electrical loads such as Autostop to Autostart transitions. Inspect for hybrid battery DTCs or conditions that would reduce available hybrid

battery power such as:

* Hybrid Battery Module undervoltage / P0AFA and various DTCs

* Hybrid Battery Module overvoltage / various DTCs

* Hybrid Battery Module voltage variation / P0AFA, P0BBD

* Hybrid Battery overtemperature / P0C32

* Hybrid Battery exposure to extreme cold

瀚慖f any of the above DTCs are set or conditions are suspected, diagnose them prior to diagnosing this DTC.

2. Program the PIM with the latest software version and recheck for DTCs.

瀚慖f the DTC resets after programming or if the PIM already contains the latest software version, replace the Hybrid Battery. If the DTC

resets, replace the PIM.
