APRILIA RSV4 R User Manual

•
If shorted to positive: see that the parameter of the rear cylinders air Pressure Sensor on
the diagnosis instrument reads approx. 1200 mbar; disconnect the sensor connector: if the
value does not vary, it means that the cable is shorted between the control unit connector
and the sensor connector: restore the cable harness; Replace the sensor if the value varies.
•
If the circuit is open, shorted to negative: check the Marelli control unit connector and the
sensor connector; if not OK, restore. If everything is OK, with key set to OFF, check if there
is continuity between the PIN 24 of the Marelli control unit and the sensor connector PIN 3:
if there is no continuity, restore the cable harness. If there is continuity, check the cable
ground insulation: if there is continuity to ground, restore the cable harness; if not, with key
set to ON check that the voltage on sensor connector PIN 1 is approx. 5 V: if not OK, set
the key to OFF and check continuity between the ENGINE connector PIN 25 and the sensor
connector PIN 1: if not OK, restore the cable harness; if OK, replace the control unit; if there
is 5V voltage at PIN 1, and with key set to ON, check the continuity to ground of the sensor
connector PIN 3: if not OK, restore the cable harness; if OK, replace the sensor.

•
shorted to positive / open circuit, shorted to negative.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 49. If the circuit is open,
shorted to negative: voltage equal to zero has been detected at PIN 49.
Troubleshooting
•
If shorted to positive: see that the parameter of the front cylinders air Pressure Sensor on
the diagnosis instrument reads approx. 1200 mbar; disconnect the sensor connector: if the
value does not vary, it means that the cable is shorted between the control unit connector
and the sensor connector: restore the cable harness; Replace the sensor if the value varies.
•
If the circuit is open, shorted to negative: check the Marelli control unit connector and the
sensor connector; if not OK, restore. If everything is OK, with key set to OFF, check if there
is continuity between the PIN 49 of the Marelli control unit and the sensor connector PIN 3:
if there is no continuity, restore the cable harness. If there is continuity, check the cable
ground insulation: if there is continuity to ground, restore the cable harness; if not, with key
set to ON check that the voltage on sensor connector PIN 1 is approx. 5 V: if not OK, set
the key to OFF and check continuity between the ENGINE connector PIN 25 and the sensor
connector PIN 1: if not OK, restore the cable harness; if OK, replace the control unit; if there
is 5V voltage at PIN 1, and with key set to ON, check the continuity to ground of the sensor
connector PIN 3: if not OK, restore the cable harness; if OK, replace the sensor.
