DTC P1706 PNP SWITCH

DTC P1706 PNP SWITCHPFP:32006
Component DescriptionBBS0053Y
When the gear position is P or N, park/neutral position (PNP) switch is ON.
ECM detects the position because the continuity of the line (the ON signal) exists.
CONSULT-II Reference Value in Data Monitor ModeBBS0053Z
Specification data are reference values.
On Board Diagnosis LogicBBS00540
Overall Function CheckBBS00541
Use this procedure to check the overall function of the park/neutral position (PNP) switch circuit. During this
check, a 1st trip DTC might not be confirmed.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “P/N POSI SW” in “DATA MONITOR” mode with CON-
SULT-II. Then check the “P/N POSI SW” signal under the follow-
ing conditions.
If NG, go to EC-618, "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between ECM terminal 102 (PNP switch signal)
and ground under the following conditions.
3. If NG, go to EC-618, "
Diagnostic Procedure" .

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
