Default Help with 2002 Maxum 2100SD dash

At the end of the season my pushbutton start system stopped working. The dealer has isolated it to the keypad and module, it is not at the engine. We are not having any luck locating parts for this. Does anyone know who manufactured them for Maxum, or know where I can get parts new or used?

codeman welcome aboard. Got me on this one, maybe shrew knows.

Since I don't know this system I'll ask a few questions.

Does it use a key in a panel then a push button at the helm? Large cruisers have used this.
Is there a key fob?
Do you only have a push to start button?

Any pictures or wiring diagrams?

Welcome Aboard Codeman671!!

I second the above. The make and model of the pushbutton start would help. To be honest, I have to ask this semi-rhetorical question..What does a 'Pushbutton' start do that a 'Turnkey' start does not? I see this as potentially a complex additional with very little benefit in return. Is this an OEM pushbutton starter, or is this an aftermarket device?

Can you bypass the device to start the engine? I think these devices include an additional solenoid in the mix. I'd first verify how the thing works. I suspect it is simply shorting a circuit to complete a loop. So we start with some deductive reasoning. Is there power to the pushbutton switch? Is the circuit completed when closed?

My personal opinion on these types of things is, if to reduce complexity by removing it completely. Otherwise, by a new one and replace the one that is there.

It seems that the keypad is may by US Marine, part# 111775 however I cannot find anything on them online, nor any reference to the part. The module is made by Siemens VDO however no model# is listed on it. Here is a pic of the module. I don't have the boat here, but will attach a picture of the keypad from the Maxum owners manual as well.

Scratching my head on this one. Did you try e-bay? Also try a bayliner parts dealer.

Sorry I was being a little hasty last post. In your owners manual is there a wiring diagram that shows the wiring to this module? If so post it.

Need to verify power is getting to the unit before jumping to a bad module. Key pad may also be bad. Looks like 4 wires and 11 push buttons, I am assuming power, ground, and 2 wire data. Wiring diagram will be a big help.

Does the key pad connector go directly to the module? What else connects to this module? It has 2 connectors 1 with 20 pins and the other has 24 pins.

I found the owners manual on line. Did you verify the breaker to the helm is not tripped? Breaker panel is located in storage compartment in front of the helm.

Questions?
Is it only the start/stop function not working and all other helm buttons work?
Do you need to enter your pin for these other functions to work?

If the answer to both questions is yes then check the following.
Locate the larger gauge Red-Purple wire on the module harness it should have 12V on it with the battery switch on.
Locate the smaller gauge Red-Purple wire on the module harness it should have 12V on it after entering your pin. This provides power to the ignition system.
Locate the Yellow-Red wire on the module harness it should have 12V on it when pressing the start button.

Provide results to this post

Some info on module. See page 68 same unit as yours. There is pinout info in this document that may help with troubleshooting.
