OK or NG
OK©GO TO 17.
NG©Replace glow relay.
17 CHECK GLOW PLUG
1. Remove glow plug connecting plate.
2. Check glow plug resistance.
SEF434Y
NOTE:
+Do not bump glow plug heating element. If it is bumped, replace glow plug with a new one.
+If glow plug is dropped from a height of 10 cm (3.94 in) or higher, replace with a new one.
+If glow plug installation hole is contaminated with carbon, remove it with a reamer or suitable tool.
+Hand-tighten glow plug by turning it two or three times, then tighten using a tool to specified torque.
