Function Explanation (DTC Detection Outline)<\/p>\n

\u2022 When the charge\/discharge circuit for the power supplying the vehicle is normal, the vehicle will operate normally.<\/div>\n
\u2022 The PCM determines an over-charge malfunction by detecting that the generator terminal voltage or battery terminal voltage are abnormally high, and verification of vehicle malfunctions\/safety assurance is performed.<\/div>\n



\n<\/a><\/p>\n

Repeatability Verification Procedure<\/p>\n

1. Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC<\/a>.)<\/div>\n
2. Start the engine.<\/div>\n
3. Leave for 30 s<\/span> while idling with no electrical load.<\/div>\n
4. Leave for 30 s<\/span> while idling with high electrical load.<\/div>\n
