C93" (P1769) Steering Damper Solenoid Valve Circuit Malfunction - Suzuki GSX-R1000 2007 Service Manual

4-108 FI SYSTEM DIAGNOSIS
"C93" (P1769) STEERING DAMPER SOLENOID VALVE CIRCUIT
MALFUNCTION
DETECTED CONDITION
Steering damper control current does
C93
not flow to the solenoid valve.
With IG turned ON, ECM detects a fail-
ure of internal circuit element. Solenoid
current does not converge to the target
value. Battery voltage is 10 V or below
with the engine running.
Steering damper control current is
P1769
higher than specified value.
An abnormal current is detected during
H
the vehicle standstill. Solenoid current is
0.7 A or above.
Steering damper control current is lower
than specified value.
With IG turned ON, ECM detects a dis-
L
continuity. An abnormal current is
detected during the vehicle standstill.

INSPECTION
Step 1
1) Turn the ignition switch OFF.
2) Check the steering damper solenoid valve coupler
loose or poor contacts.
If OK, then measure the steering damper solenoid valve
resistance.
POSSIBLE CAUSE
• Steering damper solenoid valve circuit interrupter
element shorted
• Feedback current convergence failure
• Low battery voltage
• ECM malfunction
• Steering damper solenoid valve circuit shorted to
VCC
• Steering damper solenoid valve circuit open
• Steering damper solenoid valve circuit shorted
