Keypad not working.

[Pat-Oz]

Any assistance would be appreciated
Boat in question;- 210 SAN (2001 model)
Engine PCM 351 GT-40.

Issue
Start button on the key pad will not get boat out of lock mode. Cannot engage run mode or starter motor.
No power to any of the gauges on the boat. Regardless of codes entered or start button pressed.
Power is at the key pad given the horn and blower functions work.
If any of the numbers on the key pad (1,2,3 or 4) are pressed the “system indicator light” below the number 4 operates while the number is pressed.
The system indicator light does not come on after the “Master Embedded Code” has been entered and the start button released.
Have tried changing primary and secondary user codes but the problem still exists.
If holding buttons 1&4 or 1&3 down together the system light flashes when the buttons are pressed. Once released the system light stops flashing.
The start button if pressed will activate the dash back-lighting for 10 seconds. (The button works this function only)
Covering all bases
The battery has been checked
Circuit breakers are not tripped.
The bilge pump switch near the drivers kickboard is in the on position.
Point of interest. After operating the bilge pump switch a number of times while trying to trouble shoot the problem the switch operated the starter motor for a fraction of a second. It only happened twice and I can not replicate this again. (I literally mean a fraction of a second)

My thinking so far is it is most likely the 3 way switch for “Run”, “Off” and “Bilge” or the key pad has failed. Any heads up on what the problem could be? Or further things to check? Is this a common problem?

Sounds like you are on the right track with the three way switch. Thats where I would look first. But then don't take my word for it I don't claim to be an expext.

Pat-Oz, I think the 3 way switch should be in the Run or All position. I don't know if I follow correctly but you mentioned that the bilge pump switch is in the on position, I assume you mean the 3 way switch. If that is the case, you will only have power at the bilge and not the electronics. This switch should be in the Run or All position.

Did you remove the battery before the pad stopped working? Or did you do any type of maintenance on the boat before this happened, primarily on the electrical system? Inverting the +/- cables will fry your keypad.

If you are getting intermittent power on the keypad then you might have a problem with the 3 way switch or the power cable to the keypad may be lose (either from the breaker box/source of power or at the keypad connector). This does not seem to be the problem though and should still allow you to, every now and then, start the boat.

The basic "always ON" accesories on the keypad are the bilge pump, the blower and the horn. If these are working (which you mention they are), then you are indeed getting power into the keypad. Since these functions work, I would rule out a failure on the 3 way switch and focus on the keypad itself.

I would have said that the start button was not working but you mentioned that it does turn on the backlight. I would then have said that you might have a problem with the user codes but you changed these (I dont remember but think that you also have to use the start button for changing the codes). I would then have said that you should try and use the master embedded code, which you also used. With all of this done, I would say you probably have a problem with the keypad (if the system light turns on while you press each of the different numbers for each code). If the system light does not turn on while each of the corresponding buttons are pressed, then you might have a problem with a specific number botton only.

Good luck.

Here are a couple of things to look at.
The first is that the switch needs to be in the up position. Second, can you get both of the green lights to come on (accessory position)? If so, do you hear the fuel pumps? If you don't than your battery terminal clamps need to be replaced.
How charged is your battery? With the keyless ignition, you have to be really close to 12 volts. If not, it will shut the system back down.

Let me know from there.

By the way, it is an all or nothing problem if it is the key pad. If one button is bad, you have to replace the whole key pad.
Here is the proper way to change the code. First off, DON'T use the master code. With all lights off, type in the existing code that you use (not the master) then hold down the 1 and 3 button for a couple of seconds. When you let go of them, the light should blink. You can now enter your new code, press start, type the same code again and then press start. At this point, you should see the green light turn solid. To test the system to make sure that it stored the new code, type in that code and press stop. This should lock the system (all lights out on the keypad).

I have seen the system not want to accept a new code before. If that is the case, PM Frost and he will straighten you out.

Thanks all for your responses. A little more info to clear up a few points.
* When trying to start the boat the 3-way switch is in the run position. (Up position) As Twin Tip indicated this switch is working because there is power to the keypad.
* No maintenance was carried out from when the boat was last used and the problem started. (The boat is used regularly)
* System will not go into “Accessory” mode. At no point does either of the green lights go solid.
* Outside of a few basic functions the dash is dead! No solid green light, no fuel pump noise, no radio, no gauges.
* All buttons appear to work on the keypad including the Start button which lights up the backlight of the keypad for 10 seconds (This is all it does). When any of the number buttons are pressed the green light under the number 4 lights up.
* If number 1&3 or 1&4 are pressed simultaneously to change codes the green light will flash ONLY while the numbers are held down.

Does any one have a wiring diagram for the PCM 351 GT 40 year 2001. I’m after the ignition, accessaries and engine? Unfortunately no one in Western Australia is an authorised Correct Craft workshop so no one has the manuals. I’ll put this down as a separate discussion topic.
Thanks again for all of your detailed responses to my request.
Cheers

Check your battery terminal clamps before. 2001 had a problem with those. I wouldn't dig into all of the wiring just yet. You will be in for a huge headache.

[TwinTip]

As suggested by Skinautique, I would check the battery terminals and would also make sure that the battery is fully charged. If you don't have an issue with power (meaning battery), I would go back and look at the keypad.

When in the unlock mode, you should be able to use your accesories (ballast(s), heater, shower, radio, PerfectPass, etc.). Since you are only able to use the blower, heater and horn (all of which also work in the locked mode) and are not able to unlock the system, my guess is that the problem is on the keypad.

Earlier on this post it was suggested that you PM Frost for some input on this subject. I think he dealt with something similar to this before. If you are able to bypass the user codes (don't know if you are also able to bypass the master embedded code) you might be able to make use of these other functions and of course, start your boat. This will point at the problem being on the keypad.

Good luck.
