PART 14: TROUBLESHOOTING
14.1 FAQ
• Is the USB Port used for anything other than the tablet?
- There are 3 USB ports on the Alpha MUTT
®
. One is used for charging the tablet (located
on top of the faceplate) while the other two are used to update (2) separate PCB’s via
loading a firmware file over a flash drive (located on the side of the tester).
• Besides the tablet, is there any other form of removable storage?
- The tablet offers a storage expansion in the form of a micro-SD card port (not included).
• What type of memory does the tester use?
- The Alpha MUTT
®
does not house any internal memory for saving reports. All memory is
stored on the Tablet. Tablets do feature expandable storage options. Call IPA
®
Tech
Support for further information on how to expand memory.
• Does the Alpha MUTT
®
have the ability to transmit information through any type of wireless
capabilities?
- The Alpha MUTT
®
uses an RF signal of approximately 430 Mhz that can be used to
control circuits. The tablet uses Bluetooth
®
4.0 to connect to the tester to control it and
run diagnostic reports. Wi-Fi is used on the tablet for connection to the internet to share
reports.
• Can each capability be disabled?
- The Wi-Fi can be turned off while Bluetooth
®
is being used. The tablet can enter airplane
mode to turn off all wireless communication.
• Can all functions of the Alpha MUTT
®
be used without the tablet?
- Virtually every function of the ALPHA MUTT
®
can be used without the tablet, except for the
following: customized maintenance inspection templates, reporting/receipts, ABS diagrams,
1-button pass/fail result auto-scan, alternative wiring configurations, remote ammeter
readout.
• What type of security does the tablet offer?
- The Samsung tablets feature Knox Security, which is almost exclusively approved and used
by several US security and law enforcement agencies.
• How do I pair my Bluetooth
®
tablet to the Alpha MUTT
®
?
- Open the Alpha MUTT
®
app and the tablet should automatically pair with the Alpha MUTT
®
.
If the tester disconnects for some reason, tap the Bluetooth
®
icon on the top left of the Alpha
MUTT
®
app screen to re-pair the tablet. (DO NOT try to pair the tester and tablet through
the tablet’s settings screen.)
• How do I troubleshoot poor connectivity problems?
- NEVER assume a connection is a quality connection. Many ABS issues are the direct result
of poor pin or sensor connections. These poor connections can be located directly at the
ABS ECU on the trailer and typically can be found at the 7-way round nose box connection.
If you suspect poor connectivity problems, verify the 7-Way Cable is securely inserted into
the 7-way connection. Make sure the cable head is bottomed out in the connector. Always
be certain to check the 7 pins in each plug are clean and spread to proper size before using.
• The ABS information is not being sent.
- ABS information is sent via PLC (power line communication). PLC is delivered on a
frequency over the DC power wire and a loss of communication can occur from mild
corrosion or a faulty ground.
