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 Causes
- Vehicle collision
- Inverter System Controller (ISC)
- CI1 CHECK FOR BECM (BATTERY ENERGY CONTROL MODULE) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)
- Using a diagnostic scan tool, check for CMDTC s.
Are any BECMCM DTC's present?
Yes DIAGNOSE all BECMCM DTC's REFER to: DIAGNOSTIC TROUBLE CODE (DTC) CHART . No GO to CI2 - CI2 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) DTC s. GO to CI3 No DIAGNOSE all other Inverter System Controller (ISC) DTC s, REFER to the DTC chart in This Service Information. If there are no DTC s present, GO to CI4 - CI3 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. - CI4 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) DTC s.
- 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.
