Checking the power supply
- Ignition on.
Check the power supply to the stop lamp switch. Take readings between stop lamp switch terminal #1 (cable harness side) and the ground terminal. The power supply must be approximately 12 V.
If there is no power supply:
Check the power supply circuit for stop lamp switch terminal #1 (cable harness side). Check for an open-circuit. Check for a short-circuit to ground. Check for a blown fuse in the circuit.
Remedy as necessary.
