Suspension Control - Computer Command Ride (CCR/SSS)

CODE 25 LEFT REAR ACTUATOR POSITION ERROR












TEST CONDITIONS:
The Control Module will monitor actuator position voltage for correct feedback sequence during an actuator move.

FAULT CONDITIONS:
A fault is detected if the actuator position feedback sequence is incorrect, or if more than 6 seconds is required to complete a move, If actuator position feedback voltage is incorrect, set code.

ACTION TAKEN:
Record actuator position error,
Turn on "SERVICE CCR"/"SERVICE SSS" telltale lamp,
Disable faulted actuator,
Retest every 3 minutes.

DESCRIPTION:
An actuator position fault occurs when the actuator position feedback signal has not achieved and remained at the commanded actuator position within 6 seconds after the actuator has been activated. Actuator position faults result in deactivating the faulted actuators, storing error codes 23, 24, 25 or 26, and activating the "SERVICE CCR"/ "SERVICE SSS" telltale lamp. The system will continue to operate all nonfaulted actuators normally. Recovery of the faulted actuators will occur after a successful one second self diagnostic test which is repeated every 3 minutes until all faults are cleared. A mismatch of the commanded feedback signal and the actual feedback signal which occurs after the 6 seconds will not be detected as an error, The actuators will not be repositioned until the CCR system commands a new actuator position as a result of new speed / lateral accelerator switch inputs or a 3 minute retest.

NOTES ON INTERMITTENTS:
In extremely cold weather conditions (-40°F), due to the decreased viscosity of the strut fluid, the actuator may not reach position within 6 seconds and set a code.
