TPI 2068627/4 Repair guidelines regarding the procedure which must be followed in the event that Static DTC U042300 is evident within address C5 (Thermal Management control unit) after the On Board Charger (AX4) has been replaced WARNING CAUTION vehicles with a high voltage system In the event the issue is as described within the Customer statement/Workshop findings section the operative must refer to the instructions within the Measure section of this TPI Production change - Measure 1) Raise a Technical DISS query stating the following: • The 12 volt battery is draining during the charging of the high voltage battery when the using high voltage charging socket Hint: The operative is not required to wait for feedback via DISS, please continue with the onward instructions to completion 2) Referring to Rep.Gr 93 - Carry out an Inspection and classification of the Hybrid battery unit AX1 VERY IMPORTANT: In the event that the classification result of the battery is ‘Normal’ the operative should conduct the remaining steps of this TPI from step 3 However If the classification result of the battery is either ‘Danger’ or ‘Warning’ then move the car to the quarantine area and raise a DISS immediately, the operative MUST NOT continue with any other work unless instructed via the open DISS query 3) De-energise the high voltage system - RepGr 93 - Electric Drive - De-energising high - voltage system IMPORTANT: In the event that any of the plugs shown in Figures 1 and 2 are found not to be secure (primary and secondary latch are not fully locked into position) the operative must respond via the open DISS query and await feedback before conducting any further work 4) Referring to Figure 1 point A - Check and confirm the primary and secondary latches are fully locked in position • Referring to point B and inset - Check and confirm the primary and secondary latches are fully locked in position • Referring to the inset - Check and confirm the primary and secondary latches (red and black) are fully locked in position INTERNAL Figure 1 • Referring to Figure 2 (Points A,B and C) Check and confirm the primary and secondary latches are fully locked in position Figure 2 Should any issues be found, the operative MUST respond via the open DISS query ensuring all findings are included within the DISS, the operative must await feedback before conducting any further work However If no issues are found the operative should continue from step 5 5) Referring to the applicable wiring diagram - Disconnect the 12V and the high voltage connections from the On Board Charger (AX4) 6) Conduct a visual check of the On Board Charger (AX4) plugs/terminals 7) Conduct a visual check of the On Board Charger (AX4) connections and pins Should any issues be found, the operative MUST respond via open DISS query with all findings and await feedback before conducting any further work However If no issues are found the operative should continue from step 8 to completion 8) Replace the On Board Charger (AX4) Refer to Rep.Gr 93 - Charging unit 1 for high voltage battery AX4 - To remove and refit 9) Re-energise the high voltage system - RepGr 93 - Electric Drive - De-energising high - voltage system 10) Check the operation of the charging system to confirm the system is operating to specification IMPORTANT: In the event that DTC U042300 is evident in address C5 (Thermal management control unit) the operative should conduct the INTERNAL instructions from step 11 to completion However In the event that DTC U042300 Is Not evident within address C5 (Thermal management control unit) No further action is required • The DTC can be deemed as sporadic in this instance however the DTC can only be cleared by using the Self Diagnosis • Prior to clearing the DTC check there are no relevant warnings on the Drivers Instrument Panel (DIP) and it is operating to specification 11) Navigate to Self-diagnosis session (Figure 3) Figure 3 • Referring to Figure 4 - Identify Address C5 (Thermal Management control unit) • Read the event memory with the commands at the top of the display Figure 4 • Referring to Figure 5 - Delete the event by using the delete commands (CIRCLE) Figure 5 • The DTC should now be deleted (Figure 6) INTERNAL Figure 6 In the event that there is a new charging complaint after the replacement of the On Board Charger (AX4) Or DTC U042300 is evident within address C5 (Thermal management control unit) Or Related DTC’s are logged the operative MUST update the existing DISS query or raise a new technical DISS query and await feedback before conducting any further work NOTICE Warranty accounting instructions Warranty type 110 or 910 Damage service number 93 52 Damage code 00 40 Time to De -
