Dtc "C93" (P1769): Steering Damper Solenoid Valve Circuit Malfunction - Suzuki GSX-R600 Manual

1A-138 Engine General Information and Diagnosis:

DTC "C93" (P1769): Steering Damper Solenoid Valve Circuit Malfunction

Detected Condition and Possible Cause
Detected Condition
Steering damper control current does not flow to
the solenoid valve. With IG turned ON, ECM
detects a failure of internal circuit element.
C93
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 higher than
specified value. An abnormal current is detected
H
during the vehicle standstill. Solenoid current is 0.7
A or above.
P1769
Steering damper control current is lower than
specified value. With IG turned ON, ECM detects a
L
discontinuity. An abnormal current is detected
during the vehicle standstill.

Troubleshooting
CAUTION
!
When using the multi-circuit tester, do not strongly touch the terminal of the ECM coupler with a
needle pointed tester probe to prevent terminal damage.
NOTE
After repairing the trouble, clear the DTC using SDS tool. Refer to "Use of SDS Diagnosis Reset
Procedures (Page 1A-15)".
