DTC P2413: EGR System Performance

CAUTION
!
• EGR valve data initialization procedure is required when the EGR valve is replaced.
The "EGR valve initial offset" and "EGR valve last offset" parameters must be reinitialised.
Refer to "EGR Valve Data Initialization: For Diesel Engine Model in Section 1C" to carry out this
programming.
• This fault can result in a rapid and significant fouling of the diesel particulate filter. If the EGR valve
needs to be replaced to deal with the fault, it must be cleared.
NOTE
• Conditions for applying fault finding procedures to stored faults:
The fault is declared present after a road test.
• If the fault is present:
– There is heavy smoke at the exhaust.
– The Malfunction indicator light (MIL) will come on after three consecutive driving cycles (starting
+5 seconds + turn OFF ignition switch and wait 40 seconds.).
• Use service wire for any operation on the ECM connectors.
Troubleshooting
Check the connections of the EGR valve.
Check the ECM connections.
Repair if necessary.
• Check the operation of the EGR valve:
Perform Test 7 referring to "Test 7: Exhaust gas recirculation valve: For Diesel Engine Model".
• If the fault if still present, perform "Initialization EGR valve data" on SUZUKI scan tool to reinitialize the
operating values of the valve and launch a programming procedure for the EGR offsets (Refer to "EGR Valve
Data Initialization: For Diesel Engine Model in Section 1C").
If the valve is jammed or irrevocably seized, replace the EGR valve.
