DTC Troubleshooting

WARNING: This page is about a different car, the 2010 Suzuki Kizashi. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: This DTC might be detected when battery is run down or the voltage is very low.

DIAGNOSIS PROCEDURE

Step	Action	YES	NO
1	IG1 relay power supply circuit (switch side) check Confirm that ignition mode of keyless push start system is "OFF". Remove IG1 relay. Check that voltage between "A2" circuit terminal of IG1 relay connector and ground is battery voltage. Is it in good condition?	Go to Step 2.	Repair or replace defective wire harness and "IGN" fuse.
2	Fuse check Check "MTR" fuse. Is it in good condition?	Go to Step 4.	Go to Step 3.
3	IG1 relay signal circuit check Push engine switch to change ignition mode to "OFF". Disconnect "L01" connector. Check for proper terminal connection to "L01" connector. If connections are OK, check the following points. Resistance between "B2" circuit and ground: infinity Resistance between "B2" circuit terminal and each terminal at IG1 relay connector: infinity Are they in good condition?	Replace "MTR" fuse and keyless start control module and recheck DTC, see Keyless Start Control Module Removal and Installation ..	Repair or replace defective wire harness, and then replace "MTR" fuse.
4	IG1 relay signal circuit check Push engine switch to change ignition mode to "OFF". Disconnect "L01" connector. Check for proper terminal connection to "L01" connector. If connections are OK, check the following points. Resistance of "B2" circuit: less than 3 Ω Resistance between "B2" circuit terminal and each terminal at IG1 relay connector: infinity Voltage of "B2" circuit: 0 - 1 V (with ignition mode of keyless push start system in "ON") Are they in good condition?	Go to Step 5.	Repair or replace defective wire harness.
5	IG1 relay power supply circuit (coil side) check Check the following points. Resistance of "C2" circuit: less than 3 Ω Resistance between "C2" circuit and ground: infinity Resistance between "C2" circuit terminal and each terminal at IG1 relay connector: infinity Voltage of "C2" circuit: 0 - 1 V (with ignition mode of keyless push start system in "ON") Are they in good condition?	Go to Step 6.	Repair or replace defective wire harness.
6	IG1 relay check Check IG1 relay, see CONTROL RELAY INSPECTION . Is it in good condition?	Replace keyless start control module and recheck DTC, see Keyless Start Control Module Removal and Installation ..	Replace IG1 relay.
