IR Gesture Sensor Troubleshooting
• IR Gesture Receiver is part D6500, LED2 is D6502, LED1 & 3 are on
flexes
• If no data received:
– Verify D6500 & U6500 orientation
– Verify voltage at R6590 is 5V
– Verify voltage at C6504 is 2.85 V
– Verify voltage at C6506 is 1.6 V
– Replace U6500, D6500, then U6000 or U2000 if not fixed
• One or more LEDs have low readings:
– Check black grommet on housing is not obscuring the sensor or the
LEDs
– Verify LED orientation (refer to sensor location drawing)
– Verify Q6500, Q6501, Q6502, & Q6503 orientation
– Verify voltage on LED anode is 5V
– If LED 2, replace LED module, if LED 1 or 3, replace entire flex (do
not rework on flex)
