can someone please check this for me. i dont know if pin 4 should be grounded or getting 12v. im thinking about jumping the relay. any info???
i have an sr20 redtop with ecu 62. i have an ecu pinout diagram and im getting what i think is low voltage at pin 4. it says pin 4 is main relay(ECCS) and its function should be 12v switched. so meaning 12v when the ignition is switched on.
now my problem is when i have the key on engine off im getting 0.86v at pin 4.
once i turn the car off no key in the ignition i then get 12v at pin 4.
would this mean a short?
can someone please use their DMM and check pin 4 with key on engine off and check it with key out of ignition. thanks joe
