yup. its a ckt code for #2 glowplug. its one of 3 things.
1 a failed glowplug
2 a failed buss bar
3 a failed controller
test glowplug and harness for restance from componet side of 4 pin connector if less then 2 ohms should be good and a failed controller is suspect. more then 2 ohms remove and test glowplug should be less then 2 ohms if over replace glowplug.
