Note: If the test is repeated, turn off the ignition for more than 1 minute.
1. Check the burning time of the control lamp, after turning on the ignition (ignition key in position "ON"). Compare the data with the graph.
1 - lamp burning time,
2 - system operation time.
2. Check the starting aid system.
A) Turn on the ignition (ignition key in position "ON"), but do not start the engine, check the current flow time to the glow plug relay. Compare the received data with the graph.
b) Set the ignition key to position "STA" and make sure there is voltage to the glow plugs.
V) Measure the time to apply current to the glow plug relay.
3. Start the engine, measure the electric current passing time to the glow plug relay, compare the obtained data with the graph.
