5) Dismount the Roll over sensor from its
bracket and measure the voltage when it is
leaned 65° and more, left and right, from the
horizontal level.
Roll over sensor voltage (Leaning): 3.7
– 4.4
V (+ Pu/B
– - B)
Is the voltage OK?
YES
• Y/B or Pu/B wire open or shorted to
ground, or poor 1 or 16 connection
• If wire and connection are OK,
