Case Study: KIA resolves false diagnostic trouble codes with ALLDATA Community

KIA resolves false DTCs on 2008-to-present vehicles with Alldata

The customer, KIA, faced a challenge where certain models were generating false diagnostic trouble codes due to incorrect information being sent from the battery sensor to the ECM. This occurred when an extra ground cable was installed on the negative battery terminal, disrupting the sensor's readings. The vendor, Alldata, provided a solution through its community-driven diagnostic support service, ALLDATA Community.

Alldata's solution was to diagnose the root cause and provide a verified repair procedure. The fix involved removing any additional ground cables from the negative battery terminal, clearing the stored codes, and advising customers against installing them. This simple resolution, identified by Alldata's team of experts, allowed technicians to quickly correct the problem, confirm the fix with a road test, and return the vehicles to their owners efficiently.
