How does the ignition transformer function
Just another tech asking another tech if they know what the purpose of the transformer is? Just trying to diagnose a car. Is it like a ignition module and the coil packs sequence it or how does it work?

This will help with diagnosis and testing
Power Supply Transformer
• Generates 180 volts DC (VDC)
for ignition
• Generates 23 VDC for ionic
current measurement voltage
• Supplies 12 VDC to ignition
modules
Ignition Modules
• There are 12 individual ignition
coils per ignition module
• Ignition modules convert 180
VDC to 32kv AC voltage
• 23 VDC is used to generate
voltage for ionic current
measurement
• This current is utilized along with
crankshaft position information
(L5) for misfire detection
