Detected condition and possible cause
Detected condition |
Possible cause |
||
C93 |
Steering damper control current does not flow to
the solenoid valve. With ig turned on, ecm
detects a failure of internal circuit element. Solenoid current does not converge to the target value. Battery voltage is 10 v or below with the engine running. |
|
|
P1769 | H | Steering damper control current is higher than specified value. An abnormal current is detected during the vehicle standstill. Solenoid current is 0.7 A or above. | |
L | Steering damper control current is lower than specified value. With ig turned on, ecm detects a 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” . |

Special tool Tester knob indication resistance (Ω) Steering damper solenoid valve resistance approx. 12.5 Ω at 20 °c (68 °f) Is the resistance ok? |
Go to step 2. | Replace the steering damper with a new one. |

Special tool Tester knob indication
voltage ( Steering damper solenoid valve voltage approx. 10 V when battery is fully charged condition ((+) terminal: b/bl – (–) terminal: ground) Is the voltage ok? |

Active control inspection
Note at this time, if the steering damping resistance changes from light to heavy by switching on/off, the function is normal. |
