| U0412:00 | Invalid Data Received From Battery Energy Control Module A: No Sub Type Information | DTC U0412:00 indicates a HS-CAN message from the BECM is outside normal limits due to a faulty BECM input. RETRIEVE BECM Diagnostic Trouble Codes (DTCs) and DIAGNOSE any Diagnostic Trouble Codes (DTCs) related to estimated air flow rate of air taken from cabin HVAC or high voltage battery inlet air temperature. |
| U0594:00 | Invalid Data Received From Hybrid/EV Powertrain Control Module: No Sub Type Information | DTC U0594:00 indicates a HS-CAN message from the SOBDMC is outside normal limits due to a faulty SOBDMC input. RETRIEVE SOBDMC Diagnostic Trouble Codes (DTCs) and DIAGNOSE any Diagnostic Trouble Codes (DTCs) related to the voltage on the high voltage bus at the transaxle. |
| U3000:04 | Control Module: System Internal Failure | CLEAR the DTC. If the DTC is still present, INSTALL a new Direct Current/Direct Current (DC/DC) converter control module. REFER to: DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER CONTROL MODULE - HYBRID ELECTRIC VEHICLE (HEV) . |
| U3000:41 | Control Module: General Checksum Failure | DIAGNOSE any other Direct Current/Direct Current (DC/DC) converter control module Diagnostic Trouble Codes (DTCs) first. If no other Diagnostic Trouble Codes (DTCs) are present, CLEAR the DTC. If the DTC is still present, INSTALL a new Direct Current/Direct Current (DC/DC) converter control module. REFER to: DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER CONTROL MODULE - HYBRID ELECTRIC VEHICLE (HEV) . |
| U3000:42 | Control Module: General Memory Failure | DIAGNOSE any other Direct Current/Direct Current (DC/DC) converter control module Diagnostic Trouble Codes (DTCs) first. If no other Diagnostic Trouble Codes (DTCs) are present, CLEAR the DTC. If the DTC is still present, INSTALL a new Direct Current/Direct Current (DC/DC) converter control module. REFER to: DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER CONTROL MODULE - HYBRID ELECTRIC VEHICLE (HEV) . |
| U3000:45 | Control Module: Program Memory Failure | DIAGNOSE any other Direct Current/Direct Current (DC/DC) converter control module Diagnostic Trouble Codes (DTCs) first. If no other Diagnostic Trouble Codes (DTCs) are present, CLEAR the DTC. If the DTC is still present, INSTALL a new Direct Current/Direct Current (DC/DC) converter control module. REFER to: DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER CONTROL MODULE - HYBRID ELECTRIC VEHICLE (HEV) . |
| U3000:49 | Control Module: Internal Electronic Failure | If the 12V battery is on a charger, REMOVE the charger. CLEAR the DTC. If DTC U3003:49 returns, INSTALL a new Direct Current/Direct Current (DC/DC) converter control module. REFER to: DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER CONTROL MODULE - HYBRID ELECTRIC VEHICLE (HEV) . |
| U3000:96 | Control Module: Component Internal Failure | CLEAR the DTC. If the DTC is still present, INSTALL a new Direct Current/Direct Current (DC/DC) converter control module. REFER to: DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER CONTROL MODULE - HYBRID ELECTRIC VEHICLE (HEV) . |
| U3003:16 | Battery Voltage: Circuit Voltage Below Threshold | GO to PINPOINT TEST G |
