\n
1<\/div>\n<\/td>\n
\n
VERIFY DSC HU\/CM, PCM, TCM, EPS CONTROL MODULE AND ELECTRICAL SUPPLY UNIT (ESU) DTCs<\/div>\n
\u2022 Verify DSC HU\/CM, PCM, TCM, EPS control module and electrical supply unit (ESU) DTCs using the M-MDS. (See DTC INSPECTION<\/a>.)<\/div>\n
\u2022 Are there any DTCs present?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Go to applicable DTC inspection.<\/div>\n
(See DTC TABLE [DSC HU\/CM (US)]<\/a>.)<\/div>\n
(See DTC TABLE [PCM (SKYACTIV-G (US))]<\/a>.)<\/div>\n
(See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (EV6A-EL, EV6AX-EL) (US)]<\/a>.)<\/div>\n
(See DTC TABLE [ELECTRIC POWER STEERING (EPS) (US)]<\/a>.)<\/div>\n
(See DTC TABLE [BODY CONTROL MODULE (BCM) (US)]<\/a>.)<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Go to next step.<\/div>\n<\/td>\n<\/tr>\n
\n
2<\/div>\n<\/td>\n
\n
VERIFY INSTALLATION CONDITION OF VEHICLE PARTS<\/div>\n
\u2022 Verify installation condition for following:<\/div>\n
\n
\n
\u2015 Propeller shaft (including bending and joint operation)<\/div>\n
\u2015 Center bearing<\/div>\n
\u2015 Engine mount<\/div>\n
\u2015 Differential mount<\/div>\n
\u2015 Hub bearing<\/div>\n
\u2015 Exhaust system parts<\/div>\n
\u2015 ABS wheel-speed sensor<\/div>\n<\/dd>\n<\/dl>\n
\u2022 Are they properly installed?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Go to next step.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Repair or replace the malfunctioning location and perform the repair completion verification.<\/div>\n<\/td>\n<\/tr>\n
\n
3<\/div>\n<\/td>\n
\n
DETERMINE IF MALFUNCTION IS CAUSED BY REAR DIFFERENTIAL<\/div>\n
\u2022 Install tires of another brand.<\/p>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\u2022 When tires of another brand are installed, the same malfunction can occur due to conditions different from customer explanation. Be careful not to confuse it with customer complaint.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n
\u2022 Perform simulation driving at the same engine speed, gear position, and vehicle speed that customer vehicle had malfunction.<\/div>\n
\u2022 Does the same malfunction occur?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Reinstall customer\u2019s vehicle tire. Go to next step.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
i-ACTIV AWD system is normal.<\/div>\n
Reinstall customer\u2019s vehicle tire.<\/div>\n<\/td>\n<\/tr>\n
\n
4<\/div>\n<\/td>\n
\n
INSPECT REAR DIFFERENTIAL<\/div>\n
\u2022 Inspect rear differential for following:<\/div>\n
\n
\n
\u2015 Backlash<\/div>\n
\u2015 Teeth contact (See REAR DIFFERENTIAL DISASSEMBLY<\/a>.) (See REAR DIFFERENTIAL ASSEMBLY<\/a>.)<\/div>\n<\/dd>\n<\/dl>\n
\u2022 Are they normal?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Perform the repair completion verification.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Inspect malfunctioning part and adjust it if necessary.<\/div>\n
Perform the repair completion verification.<\/div>\n<\/td>\n<\/tr>\n
\n
Repair completion verification<\/div>\n<\/td>\n
\n
VERIFY THAT MALFUNCTION SYMPTOMS DO NOT RECUR AFTER REPAIR<\/div>\n
\u2022 Install\/connect the part removed\/disconnected during the troubleshooting procedure.<\/div>\n
\u2022 Has the malfunction symptom been eliminated?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Complete the symptom troubleshooting.<\/div>\n
Explain to the customer what has been repaired.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.<\/div>\n
(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(US)]<\/a>.)<\/div>\n
If the CAN communication is normal, perform the diagnosis from Step 1.<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
