DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition SOBDMC P0D33:00 DC/DC Converter Current High: No Sub Type Information This DTC sets when the inductor current reading is greater than the calibrated threshold. Possible Sources
- Vehicle collision
- Inverter System Controller (ISC)
- CO1 CHECK FOR BECM (BATTERY ENERGY CONTROL MODULE) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)
- Using a diagnostic scan tool, check for CMDTCs.
Are any BECM CMDTCs present?
Yes DIAGNOSE all BECM CMDTCs REFER to: High Voltage Battery, Mounting and Cables - Hybrid Electric Vehicle (HEV) . No GO to CO2 - CO2 CHECK FOR VEHICLE COLLISION HISTORY
- Ask the customer if the vehicle has been involved in a collision.
Was the vehicle involved in a collision?
Yes DTC may set after a vehicle collision. CLEAR the Inverter System Controller (ISC) DTCs. GO to CO3 No DIAGNOSE all other Inverter System Controller (ISC) DTCs, REFER to Diagnostic Trouble Code (DTC) Chart . If there are no DTCs present, GO to CO4 - CO3 TEST DRIVE THE VEHICLE
- Drive the vehicle making quick accelerations and decelerations.
- Using a diagnostic scan tool, perform the Inverter System Controller (ISC) self-test.
Is DTC P0D33 present?
Yes CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new Inverter System Controller (ISC). REFER to: Inverter System Controller [SOBDMC] . No The system is operating correctly at this time. The DTC may have been set due to a vehicle collision. - CO4 CHECK FOR CORRECT INVERTER SYSTEM CONTROLLER (ISC) OPERATION
- Depower the high voltage system. REFER to: High Voltage System De-energizing .
- Ignition OFF.
- Disconnect and inspect all Inverter System Controller (ISC) connectors.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the Inverter System Controller (ISC) connectors. Make sure they seat and latch correctly.
- Repower the high voltage system. REFER to: High Voltage System De-energizing .
- Check and update the Inverter System Controller (ISC) and BECM software calibrations.
- Using a diagnostic scan tool, clear the Inverter System Controller (ISC) DTCs.
- Test drive the vehicle making quick accelerations and decelerations in an attempt to reproduce the concern.
- Using a diagnostic scan tool, perform the Inverter System Controller (ISC) self-test.
