how to read blink codes
|
While most of the nice OBDII code readers can tell us which P code is causing a check engine or IMA light, it cannot tell us the subcode ( Blink code).
The photo shows which pins need to be shorted together on the Insight OBDII plug to have the car report the blink subcodes.
Short with wire and the codes are reported.
When reading the IMA blink codes, the IMA light blinks and if the check engine light is on, it will blink
Example: a 74 IMA code would be 7 slow blinks, and 4 fast blinks, if there is more than one code, the blinking will have a long pause, and then blink out the second code.It will cycle through all the codes in a circular fashion. Say there was a 74, and a 78, and a 63. The IMA light would bilnk the 74, then the 78, then the 63, and then start back with the 74 and repeat until you release the short.
