4. Position input devices at appropriate position to achieve
the appropriate output. Use the following logic chart to
determine the appropriate input condition.
5. If specific output LED is illuminated without
appropriate output function, check output harness,
connections, and component. Repair as required.
Each row (across) in the logic chart below identifies input and output requirements for each specific product function.
Product functions are listed in the left column. Symbols identify specific circuit condition including: energized to voltage,
closed to ground, and open to ground.
– Indicates a circuit closed to ground. – LED ON
O Indicates a circuit open to ground or de–energized – LED OFF
+ Indicates an energized circuit (clutch coil, solenoid, or start input) LED ON.
" " A Blank indicates a circuit that is not involved with the logic.
To troubleshoot, turn on the key without starting the engine.
Identify the specific function that does not work and work
across the logic chart. Inspect the condition of each input
LED's to ensure it matches the logic chart.
If the input LED's are correct, check the output LED. If the
output LED is illuminated but the device is not energized,
measure available voltage at the output device, continuity
of the disconnected device, and potential voltage on the
ground circuit (floating ground). Repairs will vary
depending on your findings.
6. If specific output LED is not illuminated, check both
fuses.
7. If specific output LED is not illuminated and inputs are
in appropriate condition, install new SCM and
determine if fault disappears.
