Bypass tilt sensor??

It says a couple of things about the sensor that imply a dead short will create an error. Having said that, I would try a dead short and see if the ECM reports the error. I would also leave it open and see if it reports an error. Remember you have to cycle the key to clear the error.

Now for the complication which will take input from others; it says to test it by removing it and measuring its output voltage. The problem is the number from the two sections in the manual DO NOT AGREE!

Page 641 Section 8-40

Lean angle sensor:
• Upright: it should measure 0.4–1.4

Remove the lean angle sensor and incline it more than 65 degrees.
• Overturned: it should measure 3.8–4.2

#30 Latch up detected. No normal signal is received from the lean angle sensor.
• The vehicle has overturned.
• Defective lean angle sensor.
• Malfunction in ECU.
• Improperly installed lean angle sensor.

#41 Lean angle sensor-open or short circuit detected.
• Open or short circuit in wire harness.
• Defective lean angle sensor.
• Malfunction in ECU.

=================================
Here it says how to test it:

Pgae 376, section 8-75


CHECKING THE LEAN ANGLE SENSOR
1. Remove:
• Lean angle sensor (from the bracket.)
2. Check:
• Lean angle sensor output voltage
Out of specification → Replace.

Lean angle sensor output voltage 65°: 1.0–4.0 V
a. Connect the lean angle sensor coupler to the wire harness.
b. Connect the pocket tester (DC 20 V) to the lean angle sensor coupler as shown.
• Positive tester probe Yellow/Green “1”
• Negative tester probe Black/Blue “2”

c. When turn the lean angle sensor to 65°.
d. Measure the lean angle sensor output voltage.

========================================

Bottom line, it says it wants voltage of about 0.5vdc to make the ECM happy. A dead AA battery could be handy to trick the ECM. :D
Hint: short repeatedly for 3 second intervals to kill the battery. . . dropping its voltage to .5 or so. A good battery WILL come back to life though!
