Hi all,

Iv just bought a 56 plate grande punto with a dualogic/selespeed issue i cannot select any gear its just stuck in neutral i can hear the pump slightly and the pressure holds at about 40/47 bar if i keep the car running and disconnect pressure sensor the pump cuts in ect.

Im getting a fault code P060C - Control unit faulty (Microprocessor).

iv pulled my ecu off which is a magnet marelli - 55209034, i cant seem to find one with matching part number to try to see if it is actually the ecu

any help welcome.
 
I had that code on my starjet unfortunately I needed a new one luckily I have RAC parts and Labour £500 for a new one, but it maybe to be repaired.
 
In eper that part has been substituted by the following 51808084. A search on google turned up a few. Code P060C means that the 2 cpu in the control unit that monitor the main cpu has detected a problem. (ABS control units also have 2 cpu for safety)

The ecu would detected this error under the following circumstances:

System was operating with voltage below 9V

The other 2 are just when key turned on during self test.

The control unit has gone into recover mode R1

recovery r1:
- all gears changes are inhibited
- If the vehicle is stopped neutral is selected.

Your best bet is to try a different control unit to rule out the problem. Though it is very rare for them to fail. Try to look in all the cables going to the unit to make sure they are ok.
 
This error will also appear any time the gearbox control unit issues a command and that command is not executed and it receives no error message from the sensors (the sensors all report everything is ok)so it assume the problems is with the ecu. This could be because the gear box has a fault or a problem with the fly wheel or clutch or the control unit is faulty. Have you tried clearing the fault. What is clutch degradation index?

it does clear but only for a few seconds and then it reappears
 
OBD- clear ? It reappears because the fault is still present...
 
I measured the values in my car and this is what they should be,

Proportional pressure solenoid valves (EV1 and EV2)

These control the oil pressure at the two chambers of the gear engagement- The maximum flow rate is 7 l/min with pressure differential of 10 bar.

The control current ranges from 0 to 2.5 A directly controlled by control unit
Mine is giving a reading of 1162ma during gear selection
Electrical resistance of the winding is 2.5 Ohm +/- 6% at 20°C.


Proportional flow-rate solenoid valve (EV0)

It controls the oil inlet and outlet flow of the clutch stroke actuator chamber (single action).
The maximum flow rate is 10l/min with pressure differential of 10 bar. The control current ranges from 0 to 2A

If the current is kept at around 1A (mine was as 1120ma the solenoid stays where it is. (neutral I did the measurement with the car stopped. The clutch is only engaged when you begin accelerating)

If current is less the 1A the the fluid is allowed to return to the tank and clutch is engaged.

If the current is more than 1A the the clutch is opened

Electrical resistance of the winding is 2.5 Ohm +/- 6% at 20°C.


If you are getting no reading then the control unit is not sending the signal or signal is not reaching the solenoids. Have you looked at all the cables going to the solenoids, earth? If that fails then try getting a used control unit to see if problem continues.
 
Since you bought the car have you ever managed to select any gear or drive the car?

Do you know if the clutch was ever changed?

Does the pump run when you open the door?

Have you tried to test the pump and solenoids using the diag. software (actuators tab)
Get someone to hear if the solenoids make a noise when testing.

You could also try to do a Production/service final calibration using the adjustments tab.

Does the car other ECU have any error code. Engine ecu, ABS ecu ?

Thanks i will take a look on my next day off and i had a quick look at the wiring but ill have a more indepth look

Iv never been able to select a gear since buying it.

I have no idea if clutch had been changed, i doubt it very much in anycase

The pump does operate when opening door although doesnt sound very loud but definatly runs

Pump runs from a actuator test, solenoids come up with complete status ff or it comes up failed

No other ecu have any codes
 
Solenoids ok or failed ? or failed once in a while ? Seems pretty obvious to me that if an actuator goes (intermintently) bad I would check it and replace if necessary before going (asking) further... No ?

Since the gearbox ecu wakes up when door is opened, primes the hydraulic circuit, can receive commands and engages the starter relay it is not totally dead or maybe the problem is not related to the gearbox ecu.

Like Bernievarian said could also try change the solenoid.

What color is the hydraulic fluid?

You also said the pump noise seems low this could be caused by fluid has entered the electric motor. Try removing motor and see if it is dry.



Do you get a reading form these


• Engine speed
• Brake pedal switch (position)
• Driver's side door switch (discretionary)
• gearbox oil temperature
• Accelerator pedal position
• Outside temperature
• Coolant temperature

At the bottom of multiecuscan there are many parameters that may give you information on the past health of the system (if the problem is more clutch or engaging gears)

Starting from the clutch over temperature and downwards to gearbox/clutch self calibration.

What values do you get?

just got all these reading the clutch readings are whilst running when not running there are all 14. so and so

After doing a clutch self calibration im now getting a clutch fault code also when try to do final production thing i get the clutch error to.

Would i be right in thinking i should change the clutch first ?

First thing I can see is that your battery voltage is way too low, ECUs usually don't like that, have a charger on the battery all night long and do the test/measurement/calibration again.
2nd thing, don't you know the print-screen feature on your laptop ;-) ? Takes ages to load your pictures...

Hi,

I tried with batt charged after still no luck same fault i had the microprocessor fault since i bought it but that has dissapeard now and i only have the clutch fault. Also the tablet i was using is terrible for internet lol

Thanks,

Callum
 
What reading do you get from these:


• Engine speed
• Brake pedal switch (position)
• Driver's side door switch (discretionary)
• Accelerator pedal position
• Outside temperature
• Coolant temperature
Clutch Temperature
Clutch degradation index
Clutch overtemperature time
Clutch RPM too high counter
Missed gearshift counter
Clutch insufficient release counter
Clutch engaging problem counter
Gearbox/clutch self-calibration

Your pressure also seems a bit high max should be 50bar you reading 53bar

Hi,

I had a little play with it today i can activate odd and even gear solenoid only problem is i cant start the car now as its stuck in second gear and im still getting a clutch error code and when i try self calibration i get clutch incafitant stroke error.

Thanks,

Callum
 
Sorry for my terribly poor English understanding, what does mean incafitant ? Google translate doesn't give me any result :-(
