Table 3: The Engine Starts with Difficulty
Troubleshooting
Step
1 Check that the fuel tank is correctly filled and that the fuel
type is suitable.
Is the fuel type suitable and the tank correctly filled?
2 Check the engine earths.
Check that engine speed reaches 250 rpm under the starter
motor, as displayed on SUZUKI scan tool.
Is the starter motor working properly?
3 Check ECM for DTC(s).
Is there DTC P0335?
4 Check ECM for DTC(s).
Is there DTC P0016?
5 Check that the engine earthing is in order (oxidation,
tightness, etc.).
Check the mounting, the air gap and the condition of the
sensor (overheating).
Is there in good condition?
6 Check that the fuel circuit is leak-tight.
If the fault is still present, refer to "DTC P0089: Fuel Flow
Actuator Performance: For Diesel Engine Model" of
troubleshooting for 2.DEF: Measured pressure too low.
Is there in good condition?
7 Check the following:
• Check that the heater plugs are actuated using "Pre/post
Heater Relay Control" on SUZUKI scan tool.
• Check that the fuel flow actuator are actuated using "IMV/
Flow actuator" on SUZUKI scan tool.
• Check the exhaust system referring to "Test 1: Exhaust
system check: For Diesel Engine Model".
• Check the low pressure circuit referring to "Test 2: Low
pressure circuit check: For Diesel Engine Model".
• Check for leaks in the high pressure circuit referring to
"Test 8: Injector malfunction: For Diesel Engine Model".
• Check the turbocharged air inlet circuit referring to "Test 3:
Checking the turbocharged air inlet circuit: For Diesel
Engine Model".
• Check the MAF sensor referring to "Test 4: MAF sensor:
For Diesel Engine Model".
• Check the consistency of the signal from the engine
coolant temperature sensor.
• Check that the injectors are working properly (return
leakage too high, clogging, sticking) referring to "Test 8:
Injector malfunction: For Diesel Engine Model".
• Check the engine timing (and the position of the high
pressure pump sprocket).
Is there in good condition?
8 Are the compressions correct?
