Hyundai Santa Fe (2006 year). Manual — part 720
MT -40
MANUAL TRANSAXLE (M5GF2)
DTC P1718 STEER 2 INPUT SIGNAL
COMPONENT LOCATION
EC78ED86
Refer to DTC P1717.
GENERAL DESCRIPTION
E2DC7841
Refer to DTC P1717.
DTC DESCRIPTION
EDE7BFFA
This code related to Steering Angle Sensor Signal( #2) is set when voltage of signal is above 4.5V or loss of signal is
occurred for more than 1sec. In case of ESP system applied, this code is set when can bus off or ecu enternal error is
occurred.
If failure is detected TCCU prohibits the ITM control and cuts the current to control coil.
DTC DETECTING CONDITION
E7C94F60
Item
Detecting Condition
Possible Cause
DTC Strategy
• Loss of signal out of range
Enable Conditions
• V<4.5 for 1.0 sec self clearing
Threshold Value
• Out of Range signal: Voltage >= 4.5vdc for
greater than one (1) second
Diagnostic Time
• 1 sec
MIL on condition
• 0.5 Sec
Fail Safe
• Steering Wheel Sensor input=0. The ECU will
not send current to the clutch coil
• Steering angle sensor,TCCU
connector looseness and poor
terminal to wire connection.
• Steering angle sensor
circuit open/short
• Faulty Steering angle sensor
• Faulty TCCU

The actual value may differ from it according to various engine condition.
5.
Is Steering angle sensor #2 Signal display near the specified value?
YES
▶ Fault is intermittent caused by poor contact in the sensor’s and/or TCCU’s connector or was repaired and TCCU
memory was not cleared.Thoroughly check connectors for looseness, poor connection, bending, corrosion, contam-
ination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair"
procedure.
NO
▶ Go to " Steering angle sensor Reference voltage inspection " procedure.
