Checking The Park / Neutral Position (PNP) Switch (Automatic Transmissions)
Checking the Park / Neutral position (PNP) switch (automatic transmissions)
Terminal
Connecting the Volvo Scan Tool (ST)
Is the Volvo Scan Tool (ST) connected to both the VIDA cart and the car and switched on?
Yes - FAULT FOUND
No - No Fault Found
------------------------
FAULT FOUND - Checking the response code
-------------------------------------------------
Checking the response code
- Ignition on.
- Activate the Scan Tool (ST) in MODE 2.
- Set the switch to the ON position.
- Move the gear selector from D to N or from N to D.
- Check that the Park / Neutral position (PNP) switch is OK by checking whether response code 2-2-3 is obtained.
Is response code 2-2-3 obtained?
- 1. Yes, response code 2-2-3 is obtained.
- 2. No, response code 2-2-3 is not obtained.
- 3. No, response code 3-1-1 is obtained instead.
Select one of the above options.
1 - No Fault Found
2 - Checking the function of the Park / Neutral position (PNP) switch
3 - Checking response code 3-1-1
-------------------------------------------------
Checking response code 3-1-1
The response code is obtained when the control module receives numerous input signals within 8 ms from the same component or circuit. The fault may be due to loose connections in the terminals or a faulty component.
Continue - Checking the function of the Park / Neutral position (PNP) switch
-------------------------------------------------
Checking the function of the Park / Neutral position (PNP) switch
- Check that the car can be started with the gear selector in positions N and P.
- Check that the car cannot be started with the gear selector in any other position.
Location Of Components, Passenger Compartment (Park / Neutral Position (PNP) Switch, Automatic Transmissions):
Does the Park/Neutral position (PNP) switch function?
Yes - Checking the power supply to the control module
No - Checking components
-------------------------------------------------
Checking components
Fault-trace the Park/Neutral position (PNP) switch and the associated circuit.
Hint: For further information about the circuit, see the relevant Wiring Diagram Service Manual.
Continue - Verification
-------------------------------------------------
Checking the power supply to the control module
- Ignition off.
- Disconnect the control module.
- Ignition on.
Connect a voltmeter between control module connector terminal 2 and ground.
The voltmeter should read battery voltage with the gear selector in position D. The voltmeter should read 0 V with the gear selector in positions N and P.
OK - Checking the control module connectors
Not OK - Checking for an open-circuit
-------------------------------------------------
Checking for an open-circuit
- Ignition off.
- Check the cable between the connector 24/32 terminal #10 and control module connector terminal #2 for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.
Continue - Verification
-------------------------------------------------
Checking the control module connectors
- Ignition off.
- Check control module connector terminal #2 for contact resistance and oxidation and for loose connections. Remedy contact resistance and oxidation according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault. Remedy loose connections according to Checking wiring and terminals. Intermittent faults Checking Wiring And Terminals. Intermittent Faults.
- Connect the control module.
- Connect the Volvo Scan Tool (ST) to the data link connector (DLC).
- Ignition on.
- Activate the Scan Tool (ST) in MODE 2.
- Set the switch to the ON position.
- Move the gear selector from D to N or from N to D.
- Check whether response code 2-2-3 is obtained.
Is response code 2-2-3 obtained?
Yes - Fault-tracing information
No - Replacing the component
-------------------------------------------------
Fault-tracing information
- Ignition off.
- This response code was not obtained because of loose connections in the control module connector.
Continue - FAULT FOUND
-------------------------------------------------
Replacing the component
- Ignition off.
- Replace with a new control module according to Control module Service and Repair.

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - Exit fault-tracing
No - Attempt New Test
