Code Description
Spicer’s CTIS supports multiple vehicles or setups (tire pres-
sure targets, etc.) within a single Electronic Control Unit
(ECU). This allows the ECU to be moved from vehicle to vehi-
cle and change its parameters according to vehicle type. Set-
ups can either be selected through harness wiring
configurations or "downloaded" to the ECU. Additional modifi-
cations can be made using Dana's PC based diagnostic tool.
A "Configuration Error" code results from one of two condi-
tions:
•
Typically it is the result of a system that has been
harness selected for a downloadable configuration
(customized), but has not yet been downloaded.
Downloading the appropriate OEM setup file will
clear the display indication. ECU’s that are marked
"S-307x-xxx" normally require this special attention.
A download file can be obtained from the OEM or
Dana Engineering.
•
In addition, on some legacy systems a "Configura-
tion Error" code display indicates an automatic
memory reload has occurred. In this case, pressing
the HWY and RUN FLAT buttons simultaneously will
clear the display indication. The system has reloaded
the system defaults into ECU memory, eliminating
any customization or changes (target pressures,
etc.) previously programmed.
The troubleshooting procedure involves verifying that the
harness configuration selection wires are making a good con-
nection. If the configuration wires are good, and the problem
repeatedly occurs, the ECU may need to be replaced.
