FAIL-SAFE CHART
1. Fail-safe
This function minimizes the loss of operation when any abnormality occurs in a sensor or solenoid.
Fail-safe Control List
Malfunction Part |
Function |
---|---|
Input Turbine Speed Sensor |
Shifting to only either 1st or 3rd gears is allowed. |
Counter Gear Speed Sensor |
|
ATF Temp. Sensor |
Shifting between 1st to 4th gears is allowed. |
ECT ECU Power Supply (Voltage is Low) |
When the vehicle is being driven in 6th gear, the transaxle is fixed in 6th gear. When being driven in any of 1st to 5th gears, the transaxle is fixed in 5th gear. |
CAN communication |
Shifting to only either 1st or 3rd gears is allowed. |
Knock Sensor |
Shifting between 1st to 4th gears is allowed. |
Solenoid Valve SL1, SL2, SL3 and SL4 |
The current to the failed solenoid valve is cut off and operating the other solenoid valves with normal operation performs shift control. (Shift controls in fail-safe mode are described in the table on the next page. For details, refer to Fail-Safe Control Chart) |

Cruise SET Indicator Light Circuit
DESCRIPTION
The ECM detects a cruise control switch signal and sends it to the combination
meter assembly through CAN. Then the SET indicator light comes on.
The SET indicator light circuit uses CAN for communication. If there
is a malfunct ...
