The 2002 Sea-Doo GTX is equipped with an electronic maintenance light, just like the check-engine light on a car's dashboard. When it comes on, it's telling you something is amiss. After you resolve the problem, you must clear the light so it's ready to alert you to the next problem. Clearing the light requires you to gain access to the programming in the Multipurpose Electronic Module, or MPEM. To do this, you need a "black box" -- called the MPEM Programmer -- to communicate with the Sea-Doo.
Items you will need
MPEM Programmer, with 6-pin-to-4-pin adapter
Step 1
Open the front storage area. Connect the MPEM Programmer 6-pin adapter to the 4-pin adapter provided with the programmer. Plug the male end of the 4-pin adapter into the connection under the rear edge of the front storage area opening.
Step 2
Turn the programmer on and type in your password. Press the "Menu" button -- found on the top row of buttons, second from the left -- and push the "Down" arrow until the cursor arrives at the third position, "Vehicle Info." Press "Enter."
Step 3
Push the "Down" arrow again, past "Customer Name," "Delivery Date," "Vehicle Ser. #," "Engine Parameter," "Program Key," "Hour Info" and "MPEM Info," until reaching "Bosch System." Select "Bosch System" and press "Enter."
Step 4
Select the first position, "Diagnosis," and press "Enter." The MPEM programmer will greet you with the words "Initializing Process." Following this by a few seconds will be another menu. Move past "Bosch Info" and "Read Fault" to the third selection, "Erase Fault." Press "Enter."
Step 5
Press the "Off" button on the far right of the top line of buttons on the face of the MPEM programmer. Disconnect the 4-pin connector from the on-board connector in the front storage compartment. Replace the front cover of the storage compartment and store the MPEM programmer.
