Description
The MPI® did not detect the MPEM presence signal.
Possible causes
| 1. | Bad connection between the MPI and the MPEM. |
| 2. | MPEM internal power switch is off. |
| 3. | MPEM power source failure. |
| 4. | Electrical noise on communication lines. |
Suggested actions
| 1. | If you are using a DESS® adapter, remove the adapter from the vehicle DESS post, wait for few seconds and then insert the adapter again. Maintain a light pressure on the adapter with your hand while executing the command. |
| 2. | On snowmobile MPEM, disconnect power supply adapter and reconnect it. |
| 3. | Verify the MPEM power source voltage. |
| 4. | Verify all connections between the MPI and the MPEM/ECM (VCK, MPI-2). |
