There are two types of issue codes you might encounter in the ZUS app, one is the DTC codes, AKA Diagnostic Trouble Codes, and the other is the nonda Specific Diagnostic Codes. We will elaborate on both of them.
- Diagnostic Trouble Codes
Diagnostic Trouble Codes (DTC) are the codes generated and stored by the Powertrain Control Module (PCM) when the Onboard Diagnostic (OBD) system indicates a malfunction. Simply put, when your car system diagnoses that something went wrong, it will send a code indicating the specific fault. Following a fault manual issued by the Society of Automotive Engineers (SAE), the DTC Codes tell you what the problem is and helps further diagnosis.
In 1996, a regulation about OBD and DTC codes was made mandatory for all cars sold in the United States. It specifies the standard of OBD ports and a fault code manual for all cars, which is referred to as OBD2. With this standard, it’s much easier to understand the car malfunctions and facilitates some DIY diagnosis and fixes of vehicles.
- How to Interpret Car Diagnostic Codes
The car diagnostic codes, AKA Diagnostic Trouble Codes, consists of a five-digit alphanumeric code. The formats are shown below:
If you want to learn more about a specific code, you can check it on the OBD2 codes database here.
- nonda Specific Diagnostic Codes
Currently, there are three major types of nonda codes, i.e. vehicle battery health-related issue codes, tire pressure-related issue codes, and the backup camera-related issue codes. These data are only accessible when you have installed the ZUS Smart Car Charter (for battery health), the ZUS Smart Tire Safety Monitor (for tire pressure), and the ZUS Smart Backup Camera. For each nonda code we detected, we have a complete chart which includes Possible Causes, Possible Symptoms, Description, and Possible Solutions so users can have a clear idea of what is happening to the vehicle and what are the recommendations.
Here’s an example when a high tire pressure situation is detected.
- How to Interpret nonda Specific Diagnostic Codes
Similar to the DTC codes, it consists of a five-digit alphanumeric code. All starting with the letter “N”. The formats are shown below:
