1. Set the ignition key to MAR.
2. Connect the Examiner diagnostics tool .
3. Using Examiner check that the battery voltage is higher than 11V;
if the voltage is lower, check the battery.
4. Use Examiner to see the status of the pump relay output (ON/OFF).
5. Make gear shifts until the pump activates.
6. Stop the gear shift requests and check how long the electric pump
remains on (listening to the electric pump and at the same time
watching Examiner to see when the pump relay status changes from ON
to OFF).
7. If the status of the "pump relay output" parameter is ON, but the
electric pump activation is not heard, check the electric power
supply line of the electric pump (relay, fuse……)
8. If at environment temperature (15-20 °C) the battery voltage is
greater than 11V and the "Pump relay ON" is between 4 and 14 seconds,
the electric pump operates correctly .
9. If the checks have positive results , pass on to the next step of
the diagnostics table.
NOTE:
Repeat the test several times to make sure. |
