Troubleshooting Using Dice Error Frame Finder

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.

Interference, intermittent faults, wrong messages on CAN-net (chattering modules), ground faults, and loose connections, etc., are examples of faults that can be detected using the tool DiCE Error Frame Finder during troubleshooting. The tool registers fault messages used on the CAN-net. Fault messages may be caused by short intermittent malfunctions on the CAN-net or by a control module sending fault messages. DiCE Error Frame Finder can only be used to detect CAN-faults of intermittent nature. If network does not work, use a multimeter to measure. Typical behavior for DiCE Error Frame Finder when a problem has occurred is that the blue LED flashes several times with short pauses, and then stops and then starts flashing again.

Ignition on.
Insert special tool 951 3010 (memory card) in DiCE Error Frame Finder (Volvo diagnostic tool).
Connect DiCE (Volvo diagnostic tool) to the diagnostics socket.
Note the blue LED-indicator. The indicator flashes to show detection of fault messages.

NOTE:

Certain interference may occur without any real fault

Firmwire status, green. When the green light flashes with 4 second intervals DiCE is in fault indication mode.
CAN HS, yellow. When the yellow light flashes or is on constantly there is a data flow on CAN HS.
Fault code indicator, blue. When the blue light flashes with brief flashes DiCE indicates that there are fault code signals on CAN LS or CAN HS.
CAN LS, red/orange. When the red/orange light flashes or is on constantly there is a data flow on CAN LS.

Cable fault

Shake the cables lightly and pull lightly on the connections during the check to locate any fault. Note the blue LED-indicator.

"Chatting" control modules

"Chatting" control modules may be difficult to find and troubleshooting may take time. Let the vehicle stand with DiCE connected for an extended time period. Afterwards, activate functions to provoke a malfunction. It may take up to several hours before the fault messages are sent. When the indicator starts to flash, remove the fuse for one control module at a time until the indicator stops flashing. When the indicator stops flashing, restore the fuse for the relevant control module and check that the indicator starts to flash again. Then it is likely that the problem is identified.

Remedy wiring as necessary.
