Help with 2002 Maxum 2100SD dash

[codeman671]

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.

Just got better pictures of the keypad.

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.

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

Great info, thank you! I have forwarded all of this on to the dealer to work on.

Will post the results as soon as I hear back.

I’m kind of a car guy.. so bear with me… boats are not so indifferent (and yes, I installed the engine and outdrive both in my Maxum... so I’m not new….. )

Push button starting is nothing new and is not so complex. The ONLY thing it does is complete the circuit to the trigger lead at the starter. I could wire a push button start on my 1970 Chevelle in about 10 minutes. Same goes for my 95 SBR 2100 but there is no point.

With newer technology they have proximity fobs and such that activate everything in order for the “push button” to become enabled. 2002 I’m just guessing, not so mush. I would actually love to have a look at this. Probably nothing more than an old burnt out relay.

Use a test light… continuity is continuity… if the “push button” makes a connection… the problem is further down the line. TRACE the issue, FOLLOW the power.. and find out where it stops. Electrical problems are nothing if you know what you are doing….. AND cost thousand’s if you don’t.

Darren if you review post # 9 I told the OP how to determine if the push button system was supplying 12V to the ignition and then starter. If both of these test good then he needs to work back towards the engine (ignition or starter/soleniod issue) else problem is keypad or filter module (see his pictures).

BTY: OP is having this fixed by a shop, however they don't seem to know how to troubleshoot this maxum specific system.

[codeman671]

The boat does start on a remote start box attached at the engine, so it is isolated to the dash area. I have located the source to obtain the unit (MCIU), ATS bought the line from Siemens VDO. I am going to try to find a keypad as well. Hopefully getting closer!

Thanks for the feedback and keep us posted on the progress.

codeman671 - did you ever locate parts to solve your problem? I have the same problem with my 2100 SD: combination to keyless start no longer functions, but the rest of the keypad seems to work.

[mmwjr]

BreezyPoint welcome aboard.

Codeman never came back with results.

If a keypad can not be found a keyed ignition switch can be wired in to replace it.

Fyi - this happend to my 2001 -2100SD and Maxum gave me the master code 2412314 and that is what I am still using today if that helps anyone else

Good information to know but I don’t think the OP is around this site anymore.
