Hi
I am trying to figure out next steps,
Package on the car , Engine light is not working , Resource Low Side Ignition 7
I replaced the engine indicator bulb with a known working bulb to eliminate the possibility of a faulty bulb.The ABS light and the oil pressure warning light (red oil bulb) both function correctly.
Telltale Light Circuit
Malfunction Indicator Light -- Yellow wire on Pin 3. With ignition on, 13.3v and 0v when turning key to Off.
warning light grounding signal from ECU. Blue/black wire on Pin 2 -- Motec ECU Warning light Test set to Enable/Disabled , in the Software M1 Tune 0v regardless , I noticed the voltage (Warn Light Volt) does not change , stays at 0, Fluctuates regardless of state, 0.013, erratic (I saved the config change to the ECU) , Warn light Out DC[%] jumps up when enabled
Warn light State -- Test
Warn Light Pin Diag -- Not in use , regardless of Test enabled or Disabled

I would expect that you should have pin 2 connect to 12v from the fuse box, and pin 3 connected to the M1 ECU Warning Light Resource LS Ign 7 should be OK.
