DTC DETECTION LOGIC

NOTE:
- If DTC B210E is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to
"DTC Logic" With Intelligent Key System.
- If DTC B210E is displayed with DTC B2605, first perform the trouble diagnosis for DTC B2605. Refer to
"DTC Logic" With Intelligent Key System.
- When IPDM E/R power supply voltage is low (Approx. 7 - 8 V for about 1 second), the DTC B210F may be detected.






DTC CONFIRMATION PROCEDURE


1. PERFORM DTC CONFIRMATION PROCEDURE
