OBD2 or On-Board Diagnostics displays messages for basic group styles. More comprehensible code composition has been standard since 2000. The DTC code consists of five characters and its composition will be shown in this video

Insight into programming

The basic unit for the operation of any computer is the bit. Logic 0 and 1 are expressed by a single bit. Diagnostics The error code is composed of 16 bits. The first two bits define one of the four basic circuits. The video will show you a comprehensive overview of the composition of the error report

Basic error definition

Ignition Coil 1 Primary Circuit

Cause of DTC

The purpose of this diagnostic monitor is to verify that each coil-on-plug Ignition Coil has achieved a sufficient burn. The primary winding of the Ignition Coils are supplied 12 volts from the Fused Automatic Shut Down (ASD) Relay Output circuit. The Powertrain Control Module (PCM) completes the ground circuit (low side driver) allowing the energy to build the magnetic field of the primary coil. The PCM will open the low side driver to allow the magnetic field to collapse to the secondary winding and be transferred to the spark plug. The PCM determines spark timing by monitoring engine operating parameters from the inputs of various sensors and then calculating the appropriate moment to initiate the spark event.
