Tachometer and cruise control

Post by Revran »



my 2006 gl 1800 tachometer and cruise control stopped working at the same time, I can't find a proper schematic to see if the two have common fuse. Does anyone know if they are in conjunction with each other?

From 2006-2008 Service manual:


SERVICE INFORMATION GENERAL
• The cruise control can be set when the motorcycle is running between 30 and 100 mph (48 and 160 km/h) with the transmission
in 4th or overdrive.
• The electric cruise actuator is used to control the throttle valve in this cruise control system.
• The cruise control module is integrated with the reverse control module.
• When checking the cruise control system, always follow the steps in the troubleshooting flow chart (page 22-4).

CRUISE CONTROL SYSTEM TROUBLESHOOTING

• The CRUISE ON indicator should come on when the cruise main switch is pushed to ON with the
ignition switch turned to ON.

• If the cruise actuator relay is faulty, the system will enter the fail-safe mode, and the CRUISE SET
indicator will blink when the cruise main switch is pushed to ON with the ignition switch turned to
ON.

• The cruise/reverse control module self-diagnoses the actuator clutch when the vehicle speed reaches
above 25 km/h (16 mph) with the cruise main switch pushed to ON, and the system will enter fail-safe
mode and the CRUISE SET indicator will blink if the actuator clutch is faulty.

• The cruise control system is turned off (memory is erased) when both the SET/DECEL switch and
RESUME/ACCEL switch are pushed simultaneously.

CRUISE ON indicator does not come on when the cruise main switch is pushed to ON

1. Fuse Inspection
Check for blown No. 16 ACG./CRUISE fuse.
Is fuse No. 16 blown?
YES – Replace the fuse with a new one and turn the ignition switch to ON. If the fuse blows again,
check for a short circuit in the related wires.
NO – GO TO STEP 2.

2. Cruise/Reverse Control Module Ground Line Inspection
Check the No. 20 and 52 lines at the cruise/reverse control module (page 22-10).
Is there continuity?
YES – GO TO STEP 3.
NO – Open circuit in the Green wire between the cruise/reverse control module and ground terminal.

3. Cruise/Reverse Control Module Power Input Line Inspection
Check the No. 14 line at the cruise/reverse control module (page 22-10).
Is there battery voltage?
YES – GO TO STEP 4.
NO – Open circuit in the Black/yellow wire between the cruise/reverse control module and fuse
box (No. 16 fuse).

4. CRUISE ON Indicator Line Inspection
Check the No. 13 line at the cruise/reverse control module (page 22-10).
Does the CRUISE ON indicator come on?
YES – GO TO STEP 5.
NO – GO TO STEP 8.

5. Cruise Main Switch Line Inspection
Check the No. 9 line at the cruise/reverse control module (page 22-10).
Is there battery voltage?
YES – Faulty cruise/reverse control module.
NO – GO TO STEP 6.

6. Cruise Main Switch Inspection
Check the cruise main switch (page 22-13).
Is there continuity with the cruise main switch pushed to ON?
NO – Faulty cruise main switch; replace the right handlebar switch.
YES – GO TO STEP 7.

7. Cruise Main Switch Input Line Inspection
Turn the ignition switch to ON. Measure the voltage
between the Black/yellow wire terminal (+)
of the wire harness side right handlebar switch
connector and ground (–).
Is there battery voltage?
YES – Open circuit in the Black/yellow wire
between the right handlebar switch and
cruise/reverse control module.
NO – Open circuit in the Black/yellow wire
between fuse box (No. 16 fuse) and
right handlebar switch.

8. CRUISE ON Indicator Line Continuity Inspection
Remove the combination meter (page 21-24).
Check the Blue/orange wire for continuity
between the combination meter 40P gray connector
and cruise/reverse control module 26P
black connector.
Is there continuity?
YES – GO TO STEP 9.
NO – Open circuit in the Blue/orange wire.

9. Cruise Indicator Power Input Line Inspection
Turn the ignition switch to ON. Measure the voltage
between the Black/yellow wire terminal (+)
of the combination meter 40P gray connector
and ground (–).
Is there battery voltage?
YES – Faulty meter/gauge assembly; replace it
(page 21-29).
NO – Open circuit in the Black/yellow wire
between the combination meter and
fuse box (No. 16 fuse).

INSPECTION
Tachometer does not operate
1. Combination Meter Inspection
Check that the speedometer, coolant temperature
gauge and fuel gauge operate properly.
