\n
1<\/div>\n<\/td>\n
\n
VERIFY DTC FOR RELATED MODULES<\/div>\n
\u2022 Retrieve the DSC HU\/CM, PCM, TCM (ATX) and instrument cluster DTC using the M-MDS. (See DTC INSPECTION<\/a>.)<\/div>\n
\u2022 Are any DTCs present?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Go to the 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 (ET6A-EL) (US)]<\/a>.)<\/div>\n
(See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (EV6A-EL, EV6AX-EL) (US)]<\/a>.)<\/div>\n
(See DTC TABLE [BODY CONTROL MODULE (BCM) (US)]<\/a>.)<\/div>\n<\/td>\n<\/tr>\n

No<\/div>\n<\/td>\n
\n
Go to the next step.<\/div>\n<\/td>\n<\/tr>\n
\n
2<\/div>\n<\/td>\n
\n
VERIFY IF FALSE DETECTION OF INCLINATION ANGLE CAUSED BY MALFUNCTIONING SAS CONTROL MODULE INSTALLATION<\/div>\n
\u2022 Inspect the SAS control module installation condition for the following:<\/div>\n
\n
\n
\u2015 Is the module installed with any twisting?<\/div>\n
\u2015 Is the module installed correctly?<\/div>\n<\/dd>\n<\/dl>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Go to the next step.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Repair the SAS control module installation condition, and perform the repair completion verification.<\/div>\n
(See SAS CONTROL MODULE REMOVAL\/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM – MEXICO SPEC.]<\/a>.)<\/div>\n
(See SAS CONTROL MODULE REMOVAL\/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM – US\/CANADA SPEC.]<\/a>.)<\/div>\n<\/td>\n<\/tr>\n
\n
3<\/div>\n<\/td>\n
\n
VERIFY IF MALFUNCTION CAUSED BY INITIALIZATION PROCEDURE FOR LOW-G SENSOR NOT PERFORMED<\/div>\n
\u2022 Verify if malfunction caused by initialization procedure for low-G sensor not performed.<\/div>\n
\u2022 Has the initialization for the low-G sensor been performed after replacing the DSC HU\/CM and the SAS control module?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
