Description
INFOID:0000000012198581
For CVT models, transmission range switch is turn ON when the selector lever is P or N.
For M/T models, park/neutral position (PNP) range switch is ON when the selector lever is Neutral position.
ECM detects the position because the continuity of the line (the ON) exists.

>> GO TO 2.
NO
>> GO TO 5.
2.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
>> GO TO 3.
3.
CHECK PNP SIGNAL FUNCTION
With CONSULT
1. Turn ignition switch ON.
2. Select “P/N POSI SW” in “DATA MONITOR” mode of “ENGINE” using CONSULT. Then check the “P/N
POSI SW” signal as per the following conditions.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Proceed to
EC-1066, "Diagnosis Procedure"
.
4.
PERFORM DTC CONFIRMATION PROCEDURE

• For CVT models, the signal of transmis-
sion range switch is not changed in the
process of engine starting and driving.
• For M/T models, the signal of the park/
neutral position (PNP) switch is not
changed in the process of engine starting
and driving.
• Harness or connectors
[The transmission range switch circuit is
open or shorted.(CVT models)]
[The park/neutral position (PNP) switch
circuit is open or shorted.(M/T models)]

3. Maintain the following conditions for at least 60 consecutive seconds.
CAUTION:
Always drive vehicle at a safe speed.
4. Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Proceed to
EC-1066, "Diagnosis Procedure"
.
NO
>> INSPECTION END
5.
PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to
EC-1066, "Component Function Check"
.
NOTE:
Use component function check the overall function of the transmission range switch circuit (CVT models) or
the park/neutral position (PNP) switch circuit (M/T models). During this check, a 1st trip DTC might not be con-
firmed.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Proceed to
EC-1066, "Diagnosis Procedure"
.
Component Function Check
INFOID:0000000012198583
1.
PERFORM COMPONENT FUNCTION CHECK
1. Turn ignition switch ON.
2. Check the voltage between ECM harness connector and ground as per the following conditions.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Proceed to
EC-1066, "Diagnosis Procedure"
.
