Status displayed on SUZUKI scan tool | Detecting condition | Indicator / Warning light operation |
---|---|---|
D1 | Parameter at limit minimum | Red stop warning light (gravity 2 fault) light up |
D2 | Parameter at limit maximum |
Check the condition and connection of the connectors on all sensors with a 5 V feed.
•
A/C pressure sensor
Repair if necessary.
• Boost pressure sensor • Fuel pressure sensor • APP sensor • EGR valve • MAF and IAT sensor |
Check the condition and connection of ECM connectors “E17”, “C47” and “C48”.
Repair if necessary. |
To locate any internal fault in one of the sensors with a 5 V supply (short circuit), disconnect earth of the sensors on the list above.
Clear DTC and recheck DTC. If the faulty sensor is located, check its connections and that it is in order. If necessary replace the sensor. |
Check the insulation, continuity and absence of interference resistance of the connections:
•
Between “C48-3” terminal of ECM connector and “E100-3” terminal of A/C pressure sensor
Repair if necessary.
• Between “C47-16” terminal of ECM connector and “C49-1” terminal of boost pressure sensor • Between “C47-15” terminal of ECM connector and “C91-1” terminal of fuel pressure sensor • Between “E17-4” terminal of ECM connector and “E97-3” terminal wire of APP sensor • Between “C47-17” terminal of ECM connector and “C46-4” terminal wire of EGR valve • Between “C47-18” terminal of ECM connector and “C98-5” terminal of MAF and IAT sensor |
If DTC P0641 is still detected, replace the ECM. |
