BASIC INSPECTION : DescriptionINFOID:0000000001162514
NOTE:
Only consult the tests after following the diagnostic procedure chart.
Some specific checks are grouped under the “tests” heading and are used as required in different diagnostic
charts.
BASIC INSPECTION : Special Repair Requirement (TEST 1: Low Pressure Fuel Sup-
ply System Check)
INFOID:0000000001162515
NOTE:
CAUSE
- No fuel can be seen in the transparent supply pipe leading to the pump or large air bubbles can be seen
(small air bubbles are permitted).
- engine does not start.
1.CHECK CONFORMITY
Check the conformity and presence of the fuel (gasoline instead of diesel, contaminated fuel).

- Perform “PRGRM REINITIALIZE” in WORK SUPPORT mode with CONSULT-III.
- Cranking engine for at least 15 seconds (starting speed 250 rpm)
- Check the flow rate of the fuel being collected in a graduated measuring cylinder (500 ml minimum).The
minimum flow rate must be 25 ml every 15 sec.
