The Transaxle Range Switch sends the shift lever position information to the TCM using a 12V (battery voltage) signal. When the shift lever is in the D (Drive) position the output signal of Tansaxle Range Switch is 12V and in all other positions the voltage is 0V. The TCM judges the shift lever position by reading all signals, for the Transaxle Range Switch, simultaneously.
When Inhibitor SW selects Shift range(P,R,N,D,3,2,L), input the signal to the TCM. The selected range is 12v, the remainders are all 0v. If more than 2 signals are detected for 30 seconds by PCM, the DTC will be set.
Item | Detecting Condition & Limp Home | Possible Cause |
DTC Strategy | ● Rationality circuit continuity | ● Open or short in INHIBITOR SWITCH SW ● Defective INHIBITOR SWITCH ● Defective TCM |
Enable Conditions | ● None | |
Threshold Value | ● Multiple signal | |
Diagnostic Time | ● More than 30sec | |
Fail Safe | ● Recognition as privious signal ● When you can select N RANGE to D RANGE , more than 2 signal, recognize N RANGE. ● When you can select D RANGE to N RANGE , have not signal ,recognize D RANGE. |
