DIAGNOSIS AND TESTING - GLOW PLUGS
CAUTION:
DO NOT start the engine before the glow system tests correctly.
1.
Measure the electrical resistance of the glow plug in the installed condition. Resistance should be less than 0.8Ω. The ground contact must be as close as possible to the glow plug contact
to avoid introducing errors into the measurement.
2.
If the resistance is out of tolerance, remove the glow plug and check it again separately.
3.
Use the actuator test function for the glow plug module and glow plug lamp. The design and function of the glow plug module tests each glow plug to check the complete glow system.
4.
If MIL is OFF and OBD has not recognized a malfunction of the glow system, testing is finished and the engine can be started.
5.
If MIL is still ON, check the electrical connectors of glow plugs and power up the glow plugs again.
