Test H: Diagnostic Trouble Code 26:

OPERATION:
After a strut repositioning command, the strut motors are energized at intervals of 12.5 milliseconds to allow individual strut start-up current monitoring. The system current is monitored before each strut motor is turned on and, 1 millisecond after turn on, these values are subtracted to determine the strut motor start-up current. A strut motor start-up current in excess of 1.5 amps in the RH rear strut sets diagnostic trouble code 26. The CCR controller turns on the fault indicator, but continues to operate all non-faulted struts normally.

The computer command ride (CCR) controller changes strut firmness by applying voltage to the strut motors. The strut motors are grounded by the CCR controller. The CCR controller monitors the movement and the position of the RH rear strut at terminal F3.

If the CCR controller detects that the strut position has not changed within 6 seconds of commanding a position, or that the strut is in the wrong position, it sets diagnostic trouble code 26. When diagnostic trouble code 26 is set, the system continues to operate, but the RH rear strut is disabled and the fault indicator turns on.

POSSIBLE CAUSES:
Open or short to ground in CKT 1014.
Open or short to ground in CKT 1016.
Open in CKT 1017.
Open or short in the RH rear strut motor.
