DTC Troubleshooting

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

Step Action YES NO
1  IG2 relay power supply circuit (switch side) check 
  1. Confirm that ignition mode of keyless push start system is "OFF".
  2. Remove IG2 relay.
  3. Check that voltage between "A3" circuit terminal of IG2 relay connector and ground is battery voltage.

Is it in good condition? 		 Go to Step 2. Repair or replace defective wire harness and "IGN2" fuse.
2  Fuse check 
  1. Check "IG2 SIG" fuse.

Is it in good condition? 		 Go to Step 4. Go to Step 3.
3  IG2 relay signal circuit check 
  1. Push engine switch to change ignition mode to "OFF".
  2. Disconnect "L01" connector.
  3. Check for proper terminal connection to "L01" connector.
  4. If connections are OK, check the following points.
    • Resistance between "B3" circuit and ground: infinity
    • Resistance between "B3" circuit terminal and each terminal at IG2 relay connector: infinity

Are they in good condition? 		 Replace "IG2 SIG" 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 "IG2 SIG" fuse.
4  IG2 relay signal circuit check 
  1. Push engine switch to change ignition mode to "OFF".
  2. Disconnect "L01" connector.
  3. Check for proper terminal connection to "L01" connector.
  4. If connections are OK, check the following points.
    • Resistance of "B3" circuit: less than 3 Ω
    • Resistance between "B3" circuit terminal and each terminal at IG2 relay connector: infinity
    • Voltage of "B3" 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  IG2 relay power supply circuit (coil side) check 
  1. Check the following points.
    • Resistance of "C3" circuit: less than 3 Ω
    • Resistance between "C3" circuit and ground: infinity
    • Resistance between "C3" circuit terminal and each terminal at IG2 relay connector: infinity
    • Voltage of "C3" 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  IG2 relay check 
  1. Check IG2 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 IG2 relay.
