[DML] RPM Relay/ECM/Pulse generator Diagnostics

[doctorDHD@xxxxxxx]

Tom,
 
What exactly are you trying to accomplish or find out?
 
The "signal" going to the RPM relay is on the WS wire (white with a slate  
stripe) and comes from the Ignition ECU to ignition coil  primary connection.  
It is a "tach" signal and thus you should be able  to get a reading with a 
standard automotive diagnostic tachometer.
 
If this info does not help, please give us more details about what you  need.

Is there a procedure available to test the signal going to  the RMP
relay?  Can the relay itself be tested with a 12 VDC power  supply or do
I need an alternating/pulsing current?
