Transmission Torque Reduction Signal

FAULT ID
61

TITLE
A Cable From Transaxle Control Module For Transmission Of Torque Reduction Signal

BACKGROUND
- The transaxle control module inputs a torque reduction signal (LOW) when the transaxle is shifted to the engine control module.
- Since the gear shift completes within the usually specified hours, the engine control module checks whether the input hours of the torque reduction request signal (LOW) is within the specified range.

RANGE OF CHECK
- 60 seconds or more have passed immediately after the engine was started.
- Engine speed is approx. 50 RPM or more.

SET CONDITIONS
- The voltage of the torque reduction request signal from the transaxle control module is LOW for 5.5 seconds or more.

EFFECT
Limp-in
- When the transaxle is shifted, the ignition timing delay angle control (Engine-transaxle integrated control) is not performed.

PROBABLE CAUSES
- Short circuit of torque reduction request signal wire.
- Transaxle control module failed
- Engine control module failed.
