CHECKING THE GRIP WARMERS (for
XP530D-A)
The following procedure applies to both of the
grip warmers.
1. Check:
• Grip warmer resistance
Out of specification  Replace the grip
warmer.
Grip warmer resistance (L)
1.2–1.4  (XP530D-A)
Grip warmer resistance (R)
1.2–1.5  (XP530D-A)

CHECKING THE INTAKE AIR PRESSURE
SENSOR
1. Check:
• Intake air pressure sensor output voltage
Out of specification  Replace.
Intake air pressure sensor output
voltage
3.57–3.71 at 103.0 kPa (3.57–3.71
at 1.03 kgf/cm², 3.57–3.71 at 14.9
psi)

NOTICE
Pay attention to the installing direction of the
test harness S-pressure sensor (3P) coupler
"a".
b. Connect the digital circuit tester to the test
harness S– pressure sensor (3P).
