Connection
Connection of Volvo Scan Tool (ST)
Volvo ST must be connected to both VIDA PC and vehicle to DLC in passenger compartment (models 1996-) or DLC B (models -1995).
Is Volvo ST connected and switched ON?
Yes - FAULT FOUND
No - No Fault Found
------------------------
FAULT FOUND - Checking response code
-------------------------------------------------
Checking response code
- Ignition on.
- Activate Diagnostic Test Mode (DTM) 2.
- ON/OFF selector switch to the ON position.
- Move gear shift from D to N or from N to D.
- Check that the stop (brake) light switch is OK by checking that response code 2-2-3 is returned.
Location of Components, Cruise Control (Passenger Compartment - Park/Neutral Position (PNP) Switch, Automatic Transmission):
Response code 2-2-3 returned?
- 1. Yes, response code 2-2-3 is returned.
- 2. No, response code 2-2-3 is not returned.
- 3. No, response code 3-1-1 is returned instead.
Select one of the alternatives above.
1 - No Fault Found
2 - Checking the Park/Neutral Position (PNP) switch operation
3 - Checking response code 3-1-1
-------------------------------------------------
Checking response code 3-1-1
A response code is returned when the control module receives several input signals from the same component or circuit within 8 ms. The cause of the fault can be loose connections or a defective system component.
Continue - Checking the Park/Neutral Position (PNP) switch operation
-------------------------------------------------
Checking the Park/Neutral Position (PNP) switch operation
- 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 shift in other positions.
Location of Components, Cruise Control (Passenger Compartment - Park/Neutral Position (PNP) Switch, Automatic Transmission):
Is the Park/Neutral position (PNP) switch operating correctly?
Yes - Checking power supply to control module
No - Checking component

Checking component
Fault-trace Park/Neutral position (PNP) switch and its circuit.
Continue - Verification
-------------------------------------------------
Checking power supply to control module
- Ignition off.
- Disconnect control module.
- Ignition on.
Connect a voltmeter between control module connector terminal 3T and ground.
Voltmeter should read battery voltage with the gear selector in the D-position and 0 V with the gear selector in the N- and P- positions.
OK - Checking control module connector
Not OK - Checking for an open-circuit
-------------------------------------------------
Checking for an open-circuit
- Ignition off.
- Check cable between alarm relay connector terminal 5S and control module connector terminal 3T for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Continue - Verification
-------------------------------------------------
Checking control module connector
- Ignition off.
- Check control module connector terminal 3T for contact resistance and oxidation and remedy according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault and loose connections according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
- Connect control module.
- Ignition on.
- Activate Diagnostic Test Mode (DTM) 2.
- ON/OFF selector switch to the ON position.
- Move gear shift from D to N or from N to D.
- Check whether response code 2-2-3 is returned.
Response code 2-2-3 returned?
Yes - Fault-tracing information
No - Replacing component
-------------------------------------------------
Fault-tracing information
- Ignition off.
- The response code was not returned because of loose connections in the control module connector.
Continue - FAULT FOUND
-------------------------------------------------
Replacing component
- Ignition off.
- Try a new control module according to Replacing control module Service and Repair.
Continue - Verification

Hint: After carrying out the repair, check that the fault has been remedied as follows:
- Ignition off.
- Reconnect connectors, reinstall components.
- Engine control module (ECM) connected.
- Selector switch ON.
- Ignition on.
- Move gear shift from D to N or from N to D.
- Activate Diagnostic Test Mode (DTM) 2.
- ON/OFF selector switch to the ON position.
- Move gear shift from D to N or from N to D.
- Check whether response code 2-2-3 is returned.
