Connection Issues with V4
Symptom
When running the
AutoConfig or Cable Tests, the laptop detects the hardware successfully but
fails to communicate with the ECU.
Solution
- Make sure there is very good contact in the ALDL
port (oftentimes a pin will be loose in the port itself or it has been pushed
back in the plug)
- Make sure Key is in the ON position
- If you are using the serial port, make sure it is
properly ENABLED in your laptop (and not using the IR port
instead)
- If you are using a USB/Serial Adapter, make sure
it is compatible ... many popular brands DO NOT support the proper data rates
for the P45 equpped vehicles. See the FAQ section for tested USB/Serial
solutions.
Early Windows 95/98 Installation
Problems
Symptom
While installing
TurboLink 4.0.4 Vehicle Pack 6 on an early Windows 98 or Windows 95 machine, you
get an error regarding MSXML.DLL OR ATITURBOLINK.DLL not registering.
You may also get an error if installing Internet Explorer.
Solution
UNINSTALL all TurboLink related installations
via the Add/Remove Programs feature in the CONTROL PANELS
Download the LATEST TurboLink installation (currently
V4.0.5 with VehiclePak 11). This has the fix for early Windows
installations.
Palm Pilot Hot Sync Manager
If you are using Palm's "Hot Sync" manager with your
laptop, you MAY have to disable it for TurboLink to use the COM port.
This is mainly for laptops with only one COM port and the Palm Pilot is using
the serial cradle (vs. the USB cradle).
Symptom
When you run
the Communication Test, both the "Cable Detected" and "ECM Communication" LEDs
are RED.
Palm Hot Sync Manager is
running (icon is in the System Tray).
RESOLUTION
Right
click on the Hot Sync Manager icon in the system tray and choose "EXIT". Rerun
the Communication Test to ensure cable is detected properly.
Connect to
car and use TurboLink normally.
V2.13 Bad Data Frame
PROBLEM
Occaisionally
while using TurboLink, you'll see a bad data frame, possibly with all sorts of
random malfunction codes. There doesn't seem to be any pattern to the occaisonal
"garbage data".
SOLUTION
- Check your laptop's "Power Saving" settings. Often
times a screen saver kicking in, the harddrive being shut down (to save
power), and other battery saving features will also affect the power to the
parallel port (which can result in loss of data and strange "hiccups" as
things cycle on and off) Disable all the power saving features and run the
laptop at "full bore" to see if the problem goes away. If so, turn on the
power saving features one by one, checking after each one if the problem
reoccurs. When it does, you've identified the feature (or combination of
features) that you need to avoid.
- Check the grounds on the back of the passenger's
side head CAREFULLY. There are two bolts that gound the wiring harness
back there ... one you can see from the top of the car, the other is very
difficult to see or reach and can often be better seen from underneath the
car. Look for corrosion, loose wires, cracked/brittle ring connectors, etc. As
the cars age, this is becoming more and more common.... the motor mounts get
worn, allowing more engine movement, which pulls on the wires (which are
brittle from heat and age)>
- Check the connectors on the top of the ECM
carefully for corrosion, dirt, grease, etc. If you've had a windshield leak,
often times the water will run down on top of the ECM and eventually corrode
the pins/connectors.
- Check the ALDL ground wire carefully.
- Look at the Numeric display in TurboLink ... pay
particular attention to the ECM Status field (lower right hand part of the
screen). If it says ALDL or BKUP in this field and you have the program in
"NORM|AL" mode, then your cable may need repair. Contact me at: kenmosher@turbo-link.com to get it
fixed ... I can usually fix it for FREE. All I ask is that you include a few
bucks for return shipping and insurance.
- If you are using a Power Inverter for the laptop,
try running it off of wall power in the garage. If the data "cleans up", then
the inverter is "humming" through the laptop and causing problems. More
expensive inverters often have better regulated power. Also, if you can, use
the inverter just to charge the laptop and run it off of batteries when hooked
to the car.
V2.13 Connection Issues
If you are having difficulties getting v2.13
TurboLink(tm) to connect to the car with a new computer or after you have
changed settings/jumpers in your computer, try the following:
- From the DOS prompt type:
-
- After the main screen comes up, choose "Realtime
Display" from the option list box.
- Pick "Numeric Display".
- Wait for the count down to finish and the Numeric
Screen should display.
- In the bottom left hand corner of the screen are
the following labeled fields:
-
- FS:000 - Frame size: number of bytes in the
frame expected from the car ECM
- IC:000 - Interrupt Count: number of interrupts
being received from the port
- D:0 - Data line state (either zero or one)from
the car's ECM
- I:0 - Interrupt line state (either zero or one)
from the printer port
- L:0F - command register value: value in the
register that controls the ALDL function
- Observe the "D" and "I" fields, they should be
"flickering" rapidly between 0 and 1. If not, make sure the cable is plugged
in correctly, all connections are clean and tight, and that the key is in the
"ON" position.
- The IC field should be counting rapidly up to 999
and wrapping around to 0 repeatedly. If the "D" and "I" fields are flickering,
but the IC count is not incrementing, it indicates that the IRQ (interrupts)
are not being received by TurboLink(tm) from your computer. This can be due to
a redirected LPT1 port, IRQ conflicts or and incorrectly configured LPT1 port.
Make sure your LPT1 port in in "NORMAL" or "UNIDIRECTIONAL" configuration via
whatever setup utilities are supplied with your computer. Make sure the LPT1
port is at IRQ7 (or IRQ5) and that the TurboLink(tm) Preferences are chosen
that correspond with that IRQ.
- The FS field should be 25 for an '86-87 TR, '89
TTA, or VIN3 SFI motor, regardless of ECM mode. It should be 9 for '84-85
Turbo Regals/Rivieras in the NORMAL mode and 23 for the ALDL mode.
- If the D & I fields are flickering, the IC is
going up, and there is still no valid data on the screen, there are a couple
of possibilities:
- The LPT1 port has been redirected
- IRQs are conflicting and it is getting interrupts
from some other device (CD ROM drive, Aux. disk drive, aux. comm card or
modem). If the IC continues to count up, even with the cable not connected to
the car, this is likely that case. Ensure the IRQ shown in your setup utility
for LPT1 and the option chosen for the IRQ in TurboLink(tm) match.
- The jumper is backwards (see the user manual). Put
the jumper in the other position.
