CIRCUIT OPERATION
The TCL/ASC-ECU and the steering wheel sensor are connected each other
via a CAN bus line, and the sensor sends the steering wheel angle and angular
velocity information to the ECU.
TCL/ASC DTC SET CONDITIONS
These diagnostic trouble codes will be set under the cases below.
DTC C1505: STEERING ANGLE SENSOR (SIGNAL SEIZURE OR ABNORMAL NEUTRAL POINT)
The steering wheel sensor output value does not fluctuate for more than 20
seconds although the vehicle speed is 15 km/h or more and the G and yaw rate
sensor output value is fluctuating. The neutral point has been +/- 180 deg or more and the vehicle speed remains
10 km/h or more for at least one second.
DTC C1506: STEERING ANGLE SENSOR (ABNORMAL STEERING ANGLE)
The steering wheel sensor sets the DTC.
TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
Current trouble
Damaged wiring harness or connector. Malfunction of the steering wheel sensor Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU)
Past trouble Carry out diagnosis with particular emphasis on connector(s) or wiring harness
between the TCL/ASC-ECU and the steering sensor. For diagnosis procedures,
refer to HOW TO TREAT PAST TROUBLE
and (Refer to HOW TO USE
TROUBLESHOOTING/INSPECTION SERVICE POINTS
).
DIAGNOSIS
sensor first when the steering wheel sensor-related
DTC is set.

6. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1505 or C1506 set?
YES < C1505 is set>: Go to Step 3.
YES < C1506 is set>: Check the steering wheel sensor DTC, and
diagnose the DTC (Refer to DTC U1433: DYNAMIC RANGE ERROR
TPS, DTC SET CONDITION
).
NO: The procedure is complete.
STEP 3. Using scan tool MB991958, check data list item 32: Steering
angle.
1. Connect scan tool MB991958 to the data link connec
tor. CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.

2. Turn the ignition switch to the "ON" position.
3. Set scan tool MB991958 to data reading mode for item 32, Steering angle.
Correct angle is displayed as the steering wheel is turned.
Q: Does the steering wheel sensor send correct steering angle?
YES: Go to Step 6.
NO: Align the steering wheel sensor neutral point and carry out
calibration (Refer to STEERING WHEEL SENSOR
). Then go to Step 4.
STEP 4. Recheck for diagnostic trouble code.
Check again if the DTC is set.
1. Turn the ignition switch to the "ON" position.
2. Erase the DTC.
3. Turn the ignition switch to the "LOCK" (OFF) position.
4. Turn the ignition switch to the "ON" position.
5. Check if the DTC is set.

6. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC U1073 set?
YES: Go to Step 1.
NO: The procedure is complete.
DTC U1104: SAS CAN TIMEOUT/NOT EQUIPPED CIRCUIT OPERATION The TCL/ASC-ECU and the steering wheel sensor are connected each other via a
CAN bus line, and the sensor sends the steering wheel angle information to the
ECU. TCL/ASC DTC SET CONDITIONS
Current trouble
Connector(s) or wiring harness in the CAN bus lines between the TCL/ASC-
ECU and the steering wheel sensor, the power supply system to the steering
wheel sensor, the steering wheel sensor itself, or the TCL/ASC-ECU may be
defective.
Past trouble
Carry out diagnosis with particular emphasis on connector(s) or wiring harness
in the CAN bus lines between the steering wheel sensor and the TCL/ASC-
ECU, and the power supply system to the steering wheel sensor. For diagnosis
procedures, refer to "HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS
). CAUTION: If DTC U1104 is set in the TCL/ASC-ECU, always
diagnose the CAN bus lines.
CAUTION: Whenever the ECU is replaced, ensure that the CAN
bus lines are normal.

TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
The CAN bus line is defective. Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU) Malfunction of the steering wheel sensor
DIAGNOSIS Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable MB991910: MUT-III Main Harness A
STEP 1. Using scan tool MB991958, diagnose the CAN bus line.
Use scan tool MB991958 to diagnose the CAN bus lines.
1. Connect scan tool MB991958 to the data link connec
tor. NOTE: For a past trouble, you may not find it by the MUT-III
CAN bus diagnostics even if there is any failure in CAN
bus lines. In this case, Refer to HOW TO COPE WITH
INTERMITTENT MALFUNCTIONS
). and check the CAN
bus lines. You can narrow down the possible cause of
the trouble by referring to the DTC, which is set
regarding the CAN communication-linked ECUs (Refer
to HOW TO DIAGNOSE THE CAN BUS LINE
).
