Notice
General Information of OBDII (On-Board Diagnostics II)
Diagnostic Trouble Codes (DTCs)
Phoenix Plus may automatically reset while being disturbed by strong static electricity. THIS
IS A NORMAL REACTION.
This user manual is subject to change without written notice.
Read the instruction carefully and use the unit properly before operating. Failure to do so may
cause damage and/or personal injury, which will void the product warranty.
The OBDII system is designed to monitor emission control systems and key engine
components by performing either continuous or periodic tests of specific components and
vehicle conditions, which will offer three pieces of such valuable information:
• Whether the Malfunction Indicator Light (MIL) is commanded “on” or “off”;
• Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
• Readiness Monitor status.
