Connect a scantool and measure a primary waveform of the ignition. (Connect channel 1 probe of the scantool to #1,4 terminal of the ignition coil connector.)
A.
Specification
A : 1.4~1.8mS, B : 360~380V
If engine stalls intermittently, Perform trouble shooting by approaching classified system. Symptom of the Engine stalling by inaccurate ignition system is similar to engine stalling by cutting power supply. Because of intermittent symptom , Perform trouble shooting by checking symptoms. First of all check the primary waveform of the ignition coil.
Engine "ON"
Connect a scantool and measure a primary waveform of the ignition. (Connect channel 1 probe of the scantool to #1,4 terminal of the ignition coil connector.)
Specification
A : 1.4~1.8mS, B : 360~380V
Is the primary waveform within specification?
YES
Ignition coil is OK.
NO
Go to "Spark plug and cable Inspection" procedure.
■ Measure resistance of Ignition coil
Primary coil resistance is measured between (+) terminals and (-) terminals.
Secondary coil resistance is measured between center terminals and center terminals.
Specification of Ignition Coil Resistance
Primary Coil : 0.58Ω±10%, Secondary Coil : 8.8㏀±15%
