NameCode No. 61 - Torque reduction request and execution signal lines
Code No. 62 - Torque reduction request signal lines
Code No. 63 - Torque reduction execution signal lines
Description
If a "torque reduction executing" signal is detected for 0.2 second or more while a "no torque reduction" request signal is being output, there is a short-circuit in the torque reduction request signal line or an open circuit in the torque reduction execution signal line, and code No. 61 is output.
If a "torque reduction executing" signal is not detected four times even though 0.2 second has passed since a "torque reduction request" signal was output, there is an open circuit in the torque reduction request signal line and code No. 62 is output. If a "torque reduction permissible" signal is not detected under the following conditions, there is a short-circuit in the torque reduction execution signal line and code No. 63 is output.
The transaxle output shaft speed has been 1,000 r/min or higher after the ignition switch in turned on.
Engine speed has been 1,000 r/min or higher for 20 minutes or more after the ignition switch is turned on.
