Checking Procedure (Self-diagnosis)
WARNING: This page is about a different car, the 2011 Hyundai Elantra. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
- When battery voltage is excessively low, diagnostic trouble codes can not be read. Be sure to check the battery for voltage and the charging system before starting the test
- Diagnosis memory is erased if the battery or the TCM connector is disconnected. Do not disconnect the battery before the diagnostic trouble codes (DTC) are completely read and recorded.
