3.
Measure secondary resistance after removing a ignition coil. (Secondary resistance is measured between (+) terminals and center terminals.)
A.
Specification :
Primary Coil resistance : 0.62 ± 10% Ω
Secondary Coil resistance : 7.0 ± 15% kΩ
The purpose of the Inspection is to analyze the cause of poor power/acceleration through ignition coil inspection.
IG "OFF"
Measure primary resistance after removing ignition coil connectors. (Primary resistance is measured between (+) terminals and (-) terminals.)
Measure secondary resistance after removing a ignition coil. (Secondary resistance is measured between (+) terminals and center terminals.)
Specification :
Primary Coil resistance : 0.62 ± 10% Ω
Secondary Coil resistance : 7.0 ± 15% kΩ
Are the primary and secondary resistance of the ignition coil normal?
YES
Ignition coil is OK.
NO
Replace the ignition coil.
■ The primary ignition coil waveform Inspection
1. Engine "ON"
2. Connect a scantool to Data Link Connector(DLC).
3. Measure the primary coil waveform using oscilloscope function. (Measure the primary coil waveform between ignition coil control terminal and chassis ground.)
Specification : A : 1.0~2.0mS, B : 300~400V
