Test of system voltage
4. Fault code 34----system voltage
Second:
Maintenance according to engine failure form
Before diagnose according to the engine failure form please do the initial checks
1. Make sure that the ECU and fault indicating light is ok.
2. Make sure that there’s no fault record by checking with fault diagnosis tester or diagnostic light.
3. Check the idle speed data of electronic control system when the engine is heat and make sure the data is in the normal range.
4. Make sure that the fault do exist and search it to find the exact position.
Then check the appearance:
1. Check the joint place between cable and ground to see if it is clean and tight.
2. Check the air pipes to see if it is broken, twisted or wrong connected.
3. Check the pipe for clogging.
4. Check the connection of throttle body and air inlet pipe for proper sealing.
5. Check the high voltage wire of ignition coil for breakage and aging.
6. Check the connection of the wires for proper position. Check the joints to see if it is loose or with poor contact.

Subsequent steps
1
Check with multimeter to see if the voltage between
positive and negative terminals of the battery is about 12V.
YES
Next step
NO
Charge/check the rectifier and its charging circuits;
replace the battery
2
Open the key switch.
Next step
3
Check with multimeter to see if the voltage between the
black power wire (which is behind the key switch) and the
vehicle green ground wire is about 12V.
YES
Next step
NO
Repair or replace the cable
4
Check with multimeter to see if the voltage between the
black power wire of ECU No.6 stitch and the vehicle
green ground wire is about 12V.
YES
Replace the ECU
NO
Repair or replace the cable
