STARTER SYSTEM
Sportsman Starter Lockout Overview and Diagnostic
The Sportsman starter lockout is controlled by the ECU. Pin #20 senses the transmission signal and determines if the switch is in
Neutral or Park. Pin #24 senses when the brake is applied. When the conditions are met, the ECU will activate Pin #16 to ground
the starter solenoid. Note the ground for the transmission switch runs to the wire harness splice. The ECU will allow starting in
Neutral or Park without the brake applied. Applying the brake overrides this system and allows starting regardless of transmission
shift position.
Items to check when diagnosing a no-start condition are:
• Transmission switch for proper function
• Starter solenoid for proper function
• Brake switch for proper function
• Wire harness, loose connections/pins (including the ECU) leading to and from these components
• Proper ground to frame
Should all these items be found in working order, the ECU may be at fault.
