Component Location
General Description
The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the 4th gear ratio, while the transaxle is engaged in the 4th gear. For example, if the output speed is 1000 rpm and the 4th gear ratio is 1.115, then the input speed is 1115 rpm.
DTC Description
This code is set if the value of input shaft speed is not equal to the value of the output shaft, when multiplied by the 4th gear ratio, while the transaxle is engaged in 4th gear. This malfunction is mainly caused by mechanical troubles such as control valve sticking or solenoid valve malfuctioning rather than an electrical issue.
DTC Detecting Condition
Item | Detecting Condition | Possible Cause |
DTC Strategy | ? 4th gear incorrect ratio | ? C1 clutch ? C2 brake ? Valve-body(C1, C2 pressure system) ? TCU ? Line pressure solenoid valve(SLT) ? Shift control solenoid valve(SLC3,SLB1) |
Enable Conditions | ? ATF temp. > 20? ? Output speed > 500rpm ? TCU communication = normal ? TPS > 10% ? Shift lever switch = "D"range ? Shift gear = 4th gear |
Threshold Value | ??Input speed/4th gear ratio - output speed|=200rpm |
Diagnostic Time | ? More than 12times × more than1sec |
Fail Safe | ? Self learning control is inhibited ? Locked in 3 rd gear ? Adaptive control is inhibited |
