Transmission won't Shift at all F1

Gents,

More troubles for my 1999 355 F1 Spider:

1. Came to a stop, put brake on but was still in first when opened door. Heard a unusual clunk.

2. Car would not go into gear. Tried to shut off and re-start. Now here a cycle sound like a pump. Never hear that before.

3. Might be an issue, the engine cover now indicates it is open, even though it is not. I just washed the car and wondering if that "open hood" indicator controls if the trans engages or not. Water damage to connector??

Getting it towed tomorrow hopefully. I read somewhere that there is a way to re-set the trans when it gets stuck in neutral. Turning the key 10 times or something like that. Any thoughts there?

Thanks

a very Pissed off Boaf.

 

Yes - that switch will force the F1 to go into N

You could short the switch to test (bypass)

 

I disconnected it and closed the hood. Still hear that "pumping" sound. Going out to try the car again after it cools down.

How else can I short out the switch? Thanks.

Bob

PS if it's easier, I can call you tomorrow. Let me know

 

Bob - disconnecting will likely result in open connects (hood open). You probably need closed contacts but I'm not in front of my PC to review the circuit. A jumper wire in the connector should close the contact.

 

Can you access the plug on the engine cover switch and use some kind of electrical spray to displace the water inside the switch or connector. Anyway, it will probably work in the morning. Also make sure your door is closed.

(EDIT) Strange... I can't find a wiring diagram which shows an input into the system from these switches.

 

Thanks. I just went out and I heard the pump just keep cycling. I will try and find a jumper. I have zilch for electrical tool and supplies at my apartment. Would the pump cycling stop even with the hood open?

I just get the feeling that the light will go on until the pump builds pressure, then confirms the hood is closed. I appreciate it.

Ian - the circuit is in the WSM.

 

You start the car in N, the bonnet can be open in N with car running. The pump will run until it builds the needed pressure.

 

The F1 system probably needs to see the switch CLOSED. By disconnecting the plug to the switch, you are probably simulating an OPEN switch.

You need to put something metallic between the pins on the plug you just disconnected and left dangling down. A bit of aluminium foil might work as a temporary measure. Just don't bend the pins.

Cheers

(EDIT... Sorry.. cross-posted... also, disregard... see Taz355's post)

 

NOT for my F1.

I checkd this a long time ago and just confirmed it.

My car will shift gears if unplugged. I checked this because unlike th brake pedal switch you do not need a spare just unplug and go. My guess is the water shorted it out when closed.

Dave please check your car.

 

Just unplug it. Then check

 

Thanks Ian, I did put the wires from the release cable to close the circuit. The pump just keeps cycling... I'll try it again tomorrow when it's light. But I am not hopeful.

Bob

 

Sorry, Bob.. Disregard my post... See Grant's (Taz355) post.

By the way, the F1 manual shows two symbols with open hood symbols. Which one is illuminated?

 

Thanks guys. I did just wash the car but was driving it just fine. I believe it did short out but I would have seen it when pulling out of the car wash and when I stopped for parts. It happened when I opened the door in-gear. Now I just hear the pump on and off and the light flashes.

Bob

 

Are you positive, Grant?

 

Well what I am possitive about is that when unplugged rear bonnett went into car and shifted from neutral to first, second, then third, left for about 5 seconds, then back to neutral and shut car off.

I did not start car and try to drive because I believe I did that about 3 years ago before my long trip. I was chcking functions that could lockout transmission on trip without spares.

The brack switch is definately one that will so I hav a spare, along with the grey tyco relay, and fuses in pfw.

 

It is slightly possible that car needs to be idling.

 

Want me to check it with plug in and bonnett open but not started??

 

Sure but starting is not the issue - selecting and staying in gear is.

 

What i am saying is with 100 percent confidence is when engine not started car stays in gear without bonnets plugged in.

It may not when car started.

Its differant need to check with car started.

 

Will do tomorrow i am sick

 

It will do the 3 shifts when engine is off. But not when on Il bet you a us dollar.

 

I just checked my non-F1 engine cover switch and it's open circuit when closed, and short circuit when the cover is open. This means that pulling off the plug will produce a lid closed signal.

From the workshop manual

"2.4.10. Engine hood switch

The information of "engine hood open" is sent simultaneously to the TCU and to the alarm system ECU, through an ON-OFF switch that closes the circuit to ground.

If this occurs when the car is at a standstill, the engine is running and a gear is engaged, the system enables the buzzer and releases the gear, passing to Neutral"

Although I couldn't find a clear circuit, the text suggests that "hood open" closes the switch to ground... otherwise, wouldn't they call it a hood closed switch?

Similar text is used for the driver's door switch.

Cheers
Ian

(EDIT) Caution: Having seen the plug and trying to pull it off, I see how you could damage the wiring. For future reference, it may not be best to recommend removing the plug. You may need tools to remove the earth wire to allow sufficient wire length to remove the plug.

 

Good to know - they probably do it opposite like this for a fail safe.

This is from the WSM - although I don't understand the circuit symbol - from my knowledge of electronics (minimal) this is a bizarre format

Refresh my memory as my car has been buried under a cover for 4 moths now.

Where is the "open hood indicator" and what does it look like?

Are you looking at a warning light all the way on the left hand side of the dash? Solid or flashing?
