Checking signal Cable Rail Pressure Sensor of Volvo Engine

 

 

Tools:

 

885675 Break-out cable

 

88890074 Multimeter

 

1 Cut the current with the main switch.

 

2 Disconnect the connector from the sensor.

 

3 Connect break-out cable 885675 to the cable harness connector to the engine control unit.

 

4 Use multimeter 88890074 to do resistance measurement against the engine control unit.

 

NOTICE! Measurement is done to eliminate short circuiting or breaks in the cable to the engine control unit.

 

 

Checking injection control pressure sensor

 

Tools:

 

885675 Break-out cable

 

88890074 Multimeter

 

1 Turn ignition off.

 

2 Disconnect the connector from the sensor.

 

3 Connect break-out cable 885675 between the sensor and the engine control unit.

 

4 Use multimeter 88890074 for voltage measurement.

 

5 Turn ignition on.

 

Checking the wiring to the MPROP valve

 

Tools:

 

88890074 Multimeter

 

NOTICE! If any of the measurements shows an abnormal value, check the wiring to and from the Volvo engine interface.

 

1 Cut the current with the main switch.

 

2 Remove the connector to the MPROP.

 

3 Remove connector A from the EMS2.

 

4 Use multimeter 88890074 to do a resistance measurement against the engine control unit connector A.

 

 Checking the solenoid in the MPROP valve

 

Tools:

 

885675 Break-out cable

 

88890074 Multimeter

 

1 Cut the current with the main switch.

 

2 Remove the connector from the MPROP valve. Connect break-out cable 885675 to the valve.

 

NOTICE! Do not connect the other end of the adapter cable to the engine cable harness, since

 

this can cause a measurement error.

 

3 Use multimeter 88890074 to check the resistance in the solenoid in the MPROP valve.

 

NOTICE! Measurement is done to eliminate short circuiting or breaks in the MPROP valve.

 

VODIA Log Parameters

 

Logging throttle signal with Vodia

 

To verify the throttle signal on the J1587 bus do as follow:

 

1 Choose Log testunder the Service and maintenancemeny.

 

2 Choose MID 128, Accelerator Pedal Positionand MID 144, Throttle Calibrated Positionand press play.

 

3 Verify that booth throttle values displayed in percentage by Vodia changes simultaneous while moving the throttle.
