VERIFY TCM DTC<\/div>\n
\u2022 Perform the DTC inspection for the TCM. (See DTC INSPECTION<\/a>.)<\/div>\n
\u2022 Are any DTCs displayed?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
DTC U0074:00 or U0115:00 is displayed:<\/div>\n
\u2022 CAN communication line can be considered the cause.<\/div>\n
\n
\n
\u2015 Repair or replace the wiring harness between PCM and TCM.<\/div>\n
\u2015 Go to repair completion verification.<\/div>\n<\/dd>\n<\/dl>\n
DTC other than U0074:00 and U0115:00 is displayed:<\/div>\n
\u2022 Repair the malfunctioning location according to the applicable DTC troubleshooting. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (ET6A-EL) (US)]<\/a>.) (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (EV6A-EL, EV6AX-EL) (US)]<\/a>.)<\/div>\n<\/td>\n<\/tr>\n
