Fail-Safe Chart

FAIL-SAFE CHART
1. Description
This function minimizes the loss of the ECT functions when a malfunction occurs in each sensor or solenoid.
2. Fail-safe
(a) Fail-safe control list:





HINT: *:In addition to the switching of the shift pattern through the pattern select switch, Artificial Intelligence Shift (AI-SHIFT) control enables the TCM to estimate the road conditions and the driver's intention in order to automatically select the optimal shift pattern.

(b) Shift Solenoid Valve Normal Operation Chart:





(c) Fail-safe Control Chart:





HINT:
^ *1: Canceled at first vehicle stop.
^ *2: Not canceled at next vehicle stop.
^ *3: Fail-safe operation is canceled when each trip is started.
^ *4: Not canceled, as vehicle stop was detected at previous trip.
^ *5: For the shift solenoid valve SL1 OFF malfunction, the 3rd trip is started with the fail-safe ON.
^ Fail-safe operation is performed when the TCM detects a malfunction.

Part 4:

HINT:
^ *1: When vehicle is driven after fail-safe detection.
^ *2: After trip is started in malfunctioning state.
^ In case of an open or short circuit, the TCM stops sending the current to the open or short circuited solenoid.
