5.Finally, perform a voltage drop test to check for excessive resistance inside the relay. Place one lead of your multimeter on the positive battery terminal and the other lead on the output side of the relay. Cycle the key on and off. The reading should be less than 0.5 volts.
What are the fault codes for glow plugs?
Below are some notes on diagnosing and fixing the issues going by the fault codes. Note: The glow plug system is monitored when the glow plugs are commanded on for more than 35 seconds and battery voltage is between 11.5-14 volts.
