I've got a 2001 Cadillac deville and it says it's lost the IRC ID and IRC data code. any idea how that happen?


When a malfunction such as an open fuse to a module occurs while modules are communicating, a DTC U1001-1254 Loss of 000 Communications is set current. When the modules stop communicating the current DTC U1001-1254 Loss of 000 Communications is cleared but the history DTC remains. When the modules begin to communicate again, the module with the open fuse will not be learned by the other modules so U1000 or U1255 is set current by the other modules. If the malfunction occurs when the modules are not communicating, only U1000 or U1255 is set. Radio quit working shows Code IRC U1000 please help

What are the probable causes of DTC U1000?


DTC U1000 and U1255
Class 2 Communication Malfunction , Do you know what class 2 serial data communication network is ? What module set this code an what kind of scan tool did you use to read this code .
Modules connected to the class 2 serial data circuit monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules. When a module receives a message for a critical operating parameter, the module records the ID number of the module which sent the message for State of Health monitoring, Node Alive messages. A critical operating parameter is one which, when not received, requires that the module use a default value for that parameter. When a module does not associate an ID number with at least one critical parameter within about 5.5 seconds of beginning serial data communication, DTC U1000 or U1255 is set. When more than one critical parameter does not have an ID number associated with it, the DTC will only be reported once.
The table below list the modules on the Class 2 Serial Data Circuit that will set a U1000 or U1255 and should be actively communicating the previously described messages on the Class 2 Serial Data Circuit.

Control Module

ID Number
Body Control Module (BCM)
064
Electronic Brake Control Module (EBCM)
040
Instrument Panel Cluster (IPC)
096
Radio
128
Powertrain Control Module (PCM)
016
Sensing and Diagnostic Module (SDM)
088
Diagnostic Aids
When a malfunction such as a open fuse to a module occurs while modules are communicating, a Loss of Communication DTC is set as current. When the modules stop communicating, ignition is turned off, the current Loss Communication DTC is cleared but the history DTC remains. When the modules begin to communicate again, the ignition is turned on, the module with the open fuse will not be learned by the other modules so U1000 or U1255 is set current by the other modules. If the malfunction occurs when the modules are not communicating, only U1000 or U1255 is set.
Test Description
The numbers below refer to the step numbers on the diagnostic table.

  1. A DTC U1001 - U1254 Lost Communications with with a history status may indicate the cause of U1000 or U1255.

  2. The modules not communicating are the likely cause of U1000 or U1255. The modules that are available on the class 2 serial data circuit are listed in the Circuit Description.

  3. The module which was not communicating due to a poor connection to the class 2 serial data circuit may have set DTC U1001 - U1254 Lost Communications with for those modules that it was monitoring.

  4. The modules which can communicate indicate the module which cannot communicate. You must clear the serial data communication DTCs from these modules to avoid future misdiagnosis.

  5. If all modules are communicating, the module which set U1000 or U1255 may have done so due to some other condition.

  6. The module which set U1000 or U1255 is the likely cause of the malfunction.

1
  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. Record the DTCs set in each module. If using a Tech 2, use the Class 2 DTC Check feature to determine which modules have DTCs set.
Did you record any DTCs in the range of U1001-U1254 with a history status?
Go to Diagnostic Trouble Code (DTC) List
Go to Step 2

2
  1. Turn ON the ignition, with the engine OFF.
  2. Attempt to communicate with each module on the class 2 serial data circuit. If using a Tech 2, obtain this information using the class 2 Message Monitor feature.
  3. Record all of the modules communicating on the class 2 serial data circuit.
  4. Compare the list of modules which are communicating to the list given in Circuit Description.
Does any module on the class 2 serial data circuit not communicate?
YES - Go to Step 3
NO - Go to Step 12
Test the following circuits of the module that is not communicating for an open or short to ground:
?€¢

How to pair Motorola T4508 with Oregon Scientific TP391 ?


From what we can tell the TalkAbout T4508 is a non-USA version of the T4500. The T4508 operates in a frequency range from 409-410 MHz. Unlike the USA version which operates between 462-468 MHz.

And it looks like the TP391 operates around 466 MHz. User Guide: http://de.oregonscientific.com/ulimages/manuals2/tp391_EN.pdf

This being said, your radios might not be compatible.

Best regards.

Hi got a set T4508. One unit just gives some electronic beeps when pressing the "tone" button,and do not connect with the second unit (second unit works normal). Troubled unit can receive ok from from...


1) Check the programming to be certain they are on the same frequency.
2) Check your batteries, as it takes more energy to transmit than to receive. Swapping the batteries from the good unit to the suspect unit should tell if it is a battery issue.

In looking at the user manual for the T4500, it does not appear to have an interference eliminator code. If the T4508 were to have "code" this also would need to be programmed identically to the other radio.

Here is a link to the user guide for the T4500: http://www.giantintl.com/RadioPDFs/Outdated%20Manuals/T4500_User_Manual_E.pdf

Best regards.

My pair of t4508 handsets do not 'talk' to each other.


Check the programming of the frequency and interference code eliminator. Be certain they match one another exactly. Here is a link to the user's guide http://www.giantintl.com/RadioPDFs/Outdated%20Manuals/T4500_User_Manual_E.pdf

Also, check the battery contacts on both the radio and the battery for corrosion or film. Clean with a pencil eraser if needed.
