Action<\/p>\n<\/th>\n<\/tr>\n<\/thead>\n

\n
1<\/div>\n<\/td>\n
\n
PERFORM INITIAL LEARNING AND TCC LEARNING<\/div>\n
Perform the initial learning. (See INITIAL LEARNING [EV6A-EL, EV6AX-EL]<\/a>.)<\/div>\n
Perform TCC learning using the following procedure:<\/div>\n
\n
\n
(1) The ATF temperature is 20 \u00b0C {68 \u00b0F} or more<\/span>.<\/div>\n
(2) Constantly maintain the accelerator pedal opening angle between 20%<\/span> to 60%<\/span>.<\/div>\n
(3) Accelerate the vehicle from a stop to 1st gear and from 1st to 2nd gear.<\/div>\n
(4) Perform the shifting above (3) ten times.<\/div>\n<\/dd>\n<\/dl>\n
\u2022 Does the symptom disappear?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Symptom troubleshooting is completed.<\/div>\n<\/td>\n<\/tr>\n
\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
INSPECT SIGNAL PARTS FOR MALFUNCTION<\/div>\n
\u2022 Inspect the value at the following PCM PIDs using the M-MDS. (See PID\/DATA MONITOR INSPECTION<\/a>.)<\/div>\n
\n
\n
\u2015 APP (APP sensor)<\/div>\n
\u2015 ENG_RPM (CKP sensor)<\/div>\n<\/dd>\n<\/dl>\n
\u2022 Is there any malfunction? (See PID\/DATA MONITOR TABLE [PCM (SKYACTIV-G (US))]<\/a>.)<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Repair or replace any malfunctioning parts according to the inspection result.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Replace the automatic transaxle.<\/div>\n
