7.1 Troubleshooting - tips
NOTE - A system failure concerning the EMS system may be more likely caused by faulty connections rather than
faulty components.
Before checking the EMS system for anomalies, carry out the following verifications:
A. Electrical supply
- Battery voltage
- Burnt out fuse
- Solenoid starters
- Connectors
B. Ground to chassis
C. Fuel supply
- Faulty fuel pump
- Dirty fuel filter
D. Ignition system
- Faulty spark plug
- Faulty coil
- Faulty shielded cap
E. Intake circuit
- Dirty air cleaner
- Dirty by-pass circuit
- Faulty stepper motor
F. Other
- Incorrect timing
- Incorrect idling carburetion
- Incorrect gas valve position sensor reset
NOTE - Most EMS system anomalies are caused by loose connectors. Make sure that all connections are properly
done.
Check connectors, taking special care to the following points:
1. Check the terminals for bents.
2. Check the connectors for proper plug in.
3. Cause a slight vibration to the connector and verify whether the anomaly changes in any way.
Before replacing the EMS central unit, check for the whole system operation.
In case the anomaly disappears after replacing the EMS central unit, fit the previous central unit back and
verify whether the problems persists.
Use a multimeter with an inner resistance > 10K Ω Ω Ω Ω Ω for troubleshooting.
An improper equipment may damage the EMS central unit.
We suggest to chose equipments with a resolution above 0,1V and 0,5 Ω Ω Ω Ω Ω . Resolution should always be
above ± 2%.
