P1706
DTC P1706 PNP SWITCHComponent Description
When the shift position is P or N (A/T models), Neutral (M/T models), park/neutral position (PNP) switch is turned ON.
ECM detects the position because the continuity of the line (the ON signal) exists.
For A/T models, the park/neutral position (PNP) switch assembly also indicates a transmission range switch to detect selector lever position.
CONSULT-II Reference Value in Data Monitor Mode
On Board Diagnosis Logic
NOTE: If DTC P1706 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC U1000, U1001. Refer to EC-172, "DTC U1000, U1001 CAN COMMUNICATION LINE". CAN Communication
DTC Confirmation Procedure
CAUTION: Always drive vehicle at a safe speed.
NOTE: If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select "P/N POSI SW" in "DATA MONITOR" mode with CONSULT- II. Then check the "P/N POSI SW" signal under the given conditions.
If NG, go to "Diagnostic Procedure" below.
If OK, go to following step.
3. Select "DATA MONITOR" mode with CONSULT-II.
4. Start engine and warm it up to normal operating temperature.
5. Maintain the given conditions for at least 60 consecutive seconds.
