Thread: ACE BLEED WITH NANOCOM?

On My Nanocom there is a bleed function but there are 3 lines with 2 blank windows on each line on the screen. It says start and the adjacent has stop.
On the third line it says function start and stop. Again there is no wording in any of the blank windows.
I pressed start on the third line and the ace system groaned and fluid was moving into the Ace reservoir. There was no violent shaking of the ace arms. Has any one used nanocom for this function and actually saw some text in the boxes?

Haweye has a bleed function, and it asks to disconnect the arms ? and warns stand clear of vehicle as violent rocking can occur. Which seems extra work.

You need to update your Nanocom firmware.

There was a bug in v1.06 that messed up the ACE text which was fixed in the v1.07 firmware release that came out in March 2012.

The last update which had updates relevant to non-CANBUS vehicles is v1.12 which was released late December 2012. There have been a series of updates to the firmware since December 2013 but these are have been fixes for issues with the new CANBUS modules.

The documentation for the Nanocom modules can be downloaded from the Documentation page on the website: http://www.nanocom-diagnostics.com/documentation.php

Ace System Bleeding: During ACE system maintenance or repair, hydraulic fluid may be lost from the system and air introduced. If air is present in the primary circuit (pump, attenuator and PCV) the system will self bleed shortly after starting the engine. The unwanted air will escape when it reaches the reservoir. When air is in the secondary circuit (actuators and associated pipe work) it is necessary to perform the System Bleed procedure using this function. Both actuators are designed to allow oil and air to flow freely through them when the piston is in the fully extended position. In this position, the air will be forced out and allowed to escape to the reservoir.

Using the following procedure, it is possible to bleed the front and then the rear secondary circuits with the front secondary circuit being bled first, but it is critically important that both the front and rear actuators are bled independently.

1. The vehicle has to be parked on a 4 post ramp with the handbrake on and in park or neutral.
2. Verify that the oil reservoir is to the maximum level and that the pump is active and it generates fluid’s turbulence on the reservoir.
3. Turn off the engine, raise the car at working height and perform OIL BLEEDING STEP 1.
4. Disconnect both stabilizer links on the front axle only. Do not disconnect the stabilizer
links on the rear axles. Free the nut that holds the silent block at the end of the roll bar.
5. Push the stabilizer link on the torsion bar side end up and pull the stabilizer link on the
actuator side down simultaneously to bring the actuator to its maximum extension;
make sure that no pipes or hoses become stretched.
6. For added safety, lower the vehicle to ground height.
7. Stop the STEP 1 function if it is not yet terminated. Turn on the engine and perform the
OIL BLEEDING STEP 2 (it will take about 10 minutes) and keep the reservoir topped if the
oil decreases its level. Once the function is terminated turn off the engine
8. Perform OIL BLEEDING STEP 1 and raise the car at working height and reconnect the
links of the front axels. Stop the STEP 1 function if it is not yet terminated.
9. Disconnect both stabilizer links on the rear axle only. Free the nut that holds the silent
block at the end of the roll bar.
10. For added safety, lower the vehicle to ground height again.
11. Turn on the engine and perform the OIL BLEEDING STEP 2 (it will take about 10 minutes)
and keep the reservoir topped if the oil decreases its level. Once the function is
terminated turn off the engine
12. Raise the car at working height and reconnect the links of the front axels. Perform OIL
BLEEDING STEP 3 for a few seconds.
13. Lower the car and check the level of the oil again.

do you need to use the nancom thing to bleed the brakes on a none ACE landrover?

Hi Paul , to bonest with you I can even remember what my use datails are on the BBS site was to get access to updates.It's been a long time.
Thanks Mario
