PGM-FI Main Relay

Print
This relay is located behind the dashboard's lower cover. It consists of two individual relays. One is energized whenever the ignition is ON , thus supplying battery voltage to the Powertrain Control Module (PCM). This relay also supplies voltage to the fuel injectors, and power to the second relay. The second relay is energized for two seconds, when the engine is turned ON , to power the fuel pump.
See Figure 1

Fig. Fig. 1: Schematic of the PGM-FI relay
Testing
If the engine starts and continues to run, the PGM-FI relay is working and does not need to be replaced.
See Figure 2

Fig. Fig. 2: PGM-FI relay terminal numbers

1. Remove the relay.
2. Apply battery voltage to the number three terminal.
3. Ground the number two terminal.
4. Check for continuity between terminals five and two.
5. If continuity is detected, proceed to the step 7.
6. If there is no continuity, replace the relay.
7. Connect the number four terminal to the positive side of the battery.
8. Ground the number two terminal of the relay.
9. Check for continuity between the number five terminal and the number two terminal of the relay.
10. If there is continuity, the relay checks out "OK". If the fuel pump still does not work, test the harness.
11. If there is no continuity, replace the relay and retest.

there is a fuel injection module under the dash.if you,remove the module and check the circuit board it will have broken solders in it. our shop has fixed alot of those..a hayne smanual will show you how to take it out....sorry i do not reply.

The 2006 model uses PGM-FI (fuel injection) so it would be best if you visit your dealer for injection adjustment.

ok is agood idea, but what if it still comes on so you better contact electrician before you do that.thak you

Follow the large (3/8 in) PCV vacuum hose from the front of the intake manifold plenum (lg silver box with label PGM-FI ). It turns toward the pass. side then down between intake maifold tubes/runners to the PCV valve.

scan it first

The Fuel Injection technology will be featured in the Glamour FI which has a distinctive PGM - FI feature (Programmed Fuel Injection) a first in two-wheelers. This is an intelligent computer-controlled electronic fuel injection system which scans critical engine operating conditions through sensors and provides input to the Electronic Control Unit (ECU) to inject the accurate amount of fuel as per the requirement. The sensors include throttle position engine operating temperature intake air temperature, manifold absolute air pressure and crank angle. the Glamour FI has a Bank Angle Sensor, an industry first feature, is an important safety feature which cuts off the fuel supply and ignition, if the bike tips over (falls). Apart from these, the motorcycle has a FI Malfunction Indicator Lamp which diagnoses any malfunction of sensors and indicates the same to the rider and a LCD Fuel Gauge displays fuel level in the fuel tank which is easy to read and contemporary. Apart from the new FI technology, Hero Honda’s Glamour also showcases new body coloured grab rail and rear view mirrors.,,,

That's exactly what the problem seems to be.
