Suzuki GSX-R 1000 Service Manual: Excva adjustment
Inspect the excva operation and adjust it if necessary in the following steps:
Step 1
- Set the excva to the adjustment position. Refer to “excv cable removal and installation” (page 1k- 6).
Step 2
- Turn the ignition switch off.
- Turn the mode select switch off.
- Turn the ignition switch on and check the operation
of excva.
(Excva operation order: full close → full open → approx. 60% Open)
- Turn the mode select switch on. If dtc “c46” is not indicated on the lcd display, the adjustment is correctly completed. If “c46” is indicated, repeat the procedures from step 3 to step 4.
Step 3
- Turn the ignition switch off.
- Set up the sds tools. Refer to “self-diagnostic procedures” in section 1a .
- Turn the ignition switch on.
- Click “exhaust valve operating control” (1).
- Click “full closed” (2).
- Insert the needle pointed probes into the back side of the excva coupler (3). ((+) Y – (–) w)
- Measure the excva position sensor output voltage at excv fully closed position.
Special tool
(a): 09900–25008 (multi circuit
tester set)
(b): 09900–25009 (needle-point
probe set)
Tester knob indication
voltage (
)
Excva position sensor output voltage excv is fully closed: 0.45 ≤ Output voltage ≤ 1.4 V ((+) y - (-) W)
- If the measured voltage is less than specification, adjust the no. 1 Cable adjuster (4) as follows:
- set the excva to the adjustment position. Refer to “excv cable removal and installation” .
| Caution adjusting the no. 1 Cable with the excv fully closed can damage the excva. Be sure to adjust the no. 1 Cable with the excv set in the adjustment position. |
- Turn the no. 1 Cable adjuster (4) in or out to set the output voltage within the specified value.
| Note if c46 code is indicated after adjusting the voltage, increase the voltage to 0.9 V. |
Step 4
- Measure the excva position sensor output voltage at excv fully opened position.
Special tool
(a): 09900–25008 (multi circuit
tester set)
(b): 09900–25009 (needle-point
probe set)
Excva position sensor out put voltage excv is fully opened: 3.6 ≤ Output voltage ≤ 4.55 V ((+) y - (-) W)
- If the measured voltage is more than specification, adjust the no. 2 Cable adjuster (2) as follows:
- set the excva to the adjustment position. Refer to “excv cable removal and installation” .
| Caution adjusting the no. 2 Cable with the excv fully opened can damage the excva. Be sure to adjust the no. 2 Cable with the excv set in adjustment position. |
- Turn out the no. 2 Cable adjuster (2) in or out to set the output voltage within the specified value.
- After adjusting the excv cables, perform step 2 to confirm dtc “46” is not indicated.
