What Does The C1130 Nissan Code Mean?

According to the Nissan TSB BR16-004 and the explanation provided by Andrew Markel at Babcox Media, the C1130 code is commonly found in the ABS module but does not necessarily indicate a problem with the ABS module itself.   

When the C1130 code appears, it signifies that the data required by the ABS module from the ECM is missing or incorrect. This missing data prevents the ABS module from performing certain functions. This situation often occurs when P codes are present within the ECM, such as the P0430 and P0335. 

It’s important to note that this behavior is not unique to Nissan vehicles but is observed across various vehicle models. Modules on the CAN high-speed bus are designed to communicate with each other, and the information exchanged should be complete.
