DTC P1706 PNP SWITCH

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.

Diagnostic Procedure For M/T Models

UBS00DCK

1. 

CHECK GROUND CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect neutral position (PNP) switch harness connector.

3.

Check harness continuity between PNP switch terminal 2 and
body ground.
Refer to Wiring Diagram.

4.

Also check harness for short to power.

OK or NG

OK

>> GO TO 3. 

NG

>> GO TO 2.

2. 

DETECT MALFUNCTIONING PART

Check the following.

●

Harness connectors E33, E201

●

Harness for open or short between PNP switch and body ground

>> Repair open circuit or short to power in harness or connectors.

3. 

CHECK INPUT SIGNAL CIRCUIT

1.

Disconnect ECM harness connector.

2.

Check harness continuity between ECM terminal 22 and PNP switch terminal 1.
Refer to Wiring Diagram.

3.

Also check harness for short to ground and short to power.

OK or NG

OK

>> GO TO 5.

NG

>> GO TO 4.

5. 

CHECK PNP SWITCH

Refer to 

MT-46, "Position Switch Check"

 .

OK or NG

OK

>> GO TO 6.

NG

>> Replace PNP switch.

6. 

CHECK INTERMITTENT INCIDENT

Perform 

EC-120, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT"

 .

>> INSPECTION END.

Diagnostic Procedure For A/T Models

UBS00DCL

1. 

CHECK PNP SWITCH POWER SUPPLY CIRCUIT-I

1.

Turn ignition switch OFF.

2.

Disconnect park/neutral position (PNP) relay.

3.

Turn ignition switch ON.

4.

Shift selector lever to P or N position.

5.

Check voltage between PNP relay terminal 2 and ground with
CONSULT-II or tester.

OK or NG

OK

>> GO TO 6.

NG

>> GO TO 2.
