Suzuki GSX-R 1000 Service Manual: Side-stand / ignition interlock system parts inspection
Check the interlock system for proper operation. If the interlock system does not operate properly, check each component for damage or abnormalities. If any abnormality is found, replace the component with a new one.
Side-stand switch
- Turn the ignition switch off.
- Remove the left side cowling. Refer to “exterior parts removal and installation” in section 9d .
- Disconnect the side-stand switch coupler (1).
- Measure the voltage between g and b/w lead wires.
Special tool
: 09900–25008 (multi circuit tester
set)
Tester knob indication
diode test (
)
| Note if the tester reads 1.4 V and below when the tester probes are not connected, replace its battery. |
- Connect the side-stand switch coupler.
- Install the removed parts.
Turn signal / side-stand relay
The turn signal/side-stand relay is composed of the turn signal relay, side-stand relay and diode.
Side-stand relay
- Remove the turn signal/side-stand relay. Refer to “turn signal / side-stand relay removal and installation” .
- Check the insulation between “d” and “e” terminals using the multi-circuit tester.
- Apply 12 v to terminals “d” and “c” ((+) to “d” and (– ) to “c”) and check the continuity between “d” and “e”. If there is no continuity, replace the turn signal/ side-stand relay with a new one.

- Install the turn signal/side-stand relay. Refer to “turn signal / side-stand relay removal and installation” .
Diode inspection
- Remove the turn signal/side-stand relay. Refer to “turn signal / side-stand relay removal and installation” .
- Measure the voltage between the “a”, “b” and “c” terminals using the multi-circuit tester.

| Note if the multi circuit tester reads 1.4 V and below when the tester probes are not connected, replace its battery. |
- Install the turn signal/side-stand relay. Refer to “turn signal / side-stand relay removal and installation” .
Gear position switch
- Lift and support the fuel tank. Refer to “fuel tank removal and installation” in section 1g (page 1g- 9).
- Disconnect the gear position switch coupler (1).
| Caution when disconnecting and connecting the gear position switch coupler, make sure to turn off the ignition switch, or electronic parts may get damaged. |
- Check the continuity between bl and b lead wires with the transmission in “neutral”.

set)
Tester knob indication
continuity test (
)
- Connect the gear position switch coupler to the wiring harness.
- Insert the needle pointed probes to the lead wire coupler.
- Turn the ignition switch on and side-stand to upright position.
- Measure the voltage between p and b/w lead wires using the multi-circuit tester when shifting the gearshift lever from low to top.
Special tool
(a): 09900–25008 (multi circuit
tester set)
(b): 09900–25009 (needle-point
probe set)
Tester knob indication
voltage (
)
Gear position switch voltage (except neutral position) 0.6 V and more ((+) p – (–) b/w)
- Turn the ignition switch off.
- Install the removed parts.
