- Summary
- Some vehicles may exhibit the atx fail-safe function working with the following symptoms: the vehicle speed does not increase with engine speed the atx does not shift up or down as expected. The condition may not always be able to be reproduced and dtcs may not be stored when the vehicle is brought in. Foreign material (iron particles in the atf) may enter the atx valve body and cause a temporary malfunction of the valve body and/or sensor (atx fail-safe function activated). The fail-safe function is canceled without dtcs recorded if the malfunction goes away and does not occur again at the next drive cycle. Fail-safe function operation: if a technical fault is detected in the atx by the malfunction detection function, the fail-safe function limits the atx control (inhibits some gears or shift down functions). even in case of an atx malfunction, the fail-safe function allows minimum vehicle driveability.
