DESCRIPTION
Invalid signal from the steer sensor.
Invalid signal from the steer sensor.
Invalid signal from the steer sensor.
This fault appears when steering is con-
trolled but the sensor output remains
unchanged for more than 1 second.
The steering sensor has not been cali-
brated

SECTION 10 - DIAGNOSTIC TROUBLE CODES
• Check the steer sensor for damage.
• Check that the steer sensor is securely mounted.
• Check the steer sensor connections voltages (refer
to Section 8).
• Check the steering spindle assembly : no abnormal
play, king pin securely fasten.
• Check that the sensor is positively actuated thru all
the steering range : if necessary, proceed with a
reset of the sensor, then with a new calibration
(refer to § 9-3).
• If the sensor power is correct but its output
improper : Replace the sensor and proceed with a
calibration (refer to § 4-3 & 9-3).
• Check the steer sensor for damage.
• Check that the steer sensor is securely mounted.
• Check the steer sensor connections voltages (refer
to Section 8).
• Check the steering spindle assembly : no abnormal
play, king pin securely fasten.
• Check that the sensor is positively actuated thru all
the steering range : if necessary, proceed with a
reset of the sensor, then with a new calibration
(refer to § 9-3).
• If the sensor power is correct but its output
improper : Replace the sensor and proceed with a
calibration (refer to § 4-3 & 9-3).
• If the wheels do not steer while the function is con-
trolled :
- Pump not running : check the voltage applied to
the pump motor;
- Pump running : check the oil level; check the
hydraulic pressure and the voltage applied to the
pressure relief valve; check the steer and the direc-
tional valves; check that the steering wheels are not
obstructed nor jammed,
• If the wheels steer properly :
-Check the steer sensor for damage.
-Check that the steer sensor is securely mounted.
-Check the steer sensor connections voltages
(refer to Section 8).
-If the sensor power is correct but its output
improper: Replace the sensor and proceed with a
calibration (refer to § 4-3 & 9-3).
• Proceed with a sensor calibration (refer to §xxx).
• If the sensor can not be calibrated :
-Check the steer connection voltages (refer to Sec-
tion 8).
-If the sensor power is correct but its output
improper: Replace the sensor and proceed with a
calibrations (refer to § 9-3).
