6. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1345 set?
YES: Replace the combination meter (integrated with meter ECU). Then
go to Step 12.
NO: It can be assumed that this malfunction is intermittent. Refer to
HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE
POINTS
.
STEP 12. 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.

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.

TROUBLESHOOTING HINTS (The most likel
y causes for these DTCs are to set are:
)
Current trouble
Excessive electrical load Defective battery Damaged wiring harness or connector Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU) Charging system failed
Past trouble Carry out diagnosis with particular emphasis on connector(s) or wiring harness in
the power supply circuit (terminal 32) to the TCL/ASC-ECU. For diagnosis
procedures, refer to HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS
).
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
MB991952: ABS Check Harness
STEP 1. Using scan tool MB991958, diagnose the CAN bus line.
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.

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.
