DTC U1433: DYNAMIC RANGE ERROR TPS, DTC SET CONDITION This code is set when the MFI system sets either of DTC code Nos. P0222, P0223
or P2135. TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
Malfunction of the MFI system
DIAGNOSIS Check whether the MFI system sets either of diagnostic trouble code Nos. P0222,
P0223 or P2135, and repair if necessary (Refer to HOW TO READ AND ERASE DIAGNOSTIC TROUBLE CODE
, ).
DIAGNOSTIC TROUBLE CODE PROCEDURES < STEERING WHEEL SENSOR > DTC C1551: HALL-IC OUTPUT VOLTAGE, DTC C1552: HALL-IC OUTPUT PATTERN, DTC C1553: OPTICAL
SENSOR, DTC C1554: SPEED SENSOR IS OUT OF RANGE, DTC C1555: STEERING ANGLE SNS. OUT OF
RANGE, DTC C1608: EEPROM FAILURE
CAUTION: If there is any problem in the CAN bus lines, an
incorrect diagnostic trouble code may be set. Prior to
this diagnosis, diagnose the CAN bus lines.

CIRCUIT OPERATION
The steering wheel sensor is energized via the ignition switch, and
communicates the TCL/ASC-ECU via a CAN bus-line. The steering wheel sensor has a self-diagnosis function and a memory
function. If the diagnosis function finds a trouble, it sends these DTC codes to
the TCL/ASC-ECU. Then the ECU will illuminate the TCL/ASC indicator
light. At this time, the TCL/ASC-ECU sets DTC No. C1506 (Steering angle
sensor error).
TCL/ASC/ASC DTC SET CONDITIONS These diagnostic trouble codes will be set under the cases below. DTC C1551: HALL-IC OUTPUT VOLTAGE
The Hall cell sends incorrect voltage signal for at least one second.
DTC C1552: HALL-IC OUTPUT PATTERN
Invalid Hall cell pattern fluctuates at least once.
DTC C1553: OPTICAL SENSOR
The optical sensor output is invalid.
DTC C1554: SPEED SENSOR IS OUT OF RANGE
The sensor speed is -25°/10 ms or more.
DTC C1555: STEERING ANGLE SNS. OUT OF RANGE
The sensor is out of a predetermined operation range.
DTC C1608: EEPROM FAILURE
The sensor detects an EEPROM error. CAUTION: If these DTCs has been set, TCL/ASC-ECU related
DTC C1506 is also set. After these DTCs has been
diagnosed, don't forget to erase DTC C1506.

TROUBLESHOOTING HINTS (The most likel
y causes for these DTCs are to set are:
)
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.
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. Diagnose the CAN bus line.
4. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line found to be normal?
YES: Go to Step 2.
NO: Repair the CAN bus line (Refer to DIAGNOSTIC TROUBLE
CODE DIAGNOSIS
or DIAGNOSIS < VEHICLES WITHOUT
ADVANCED AIR BAG
). Then go to Step 2.
STEP 2. Recheck for steering wheel sensor diagnostic trouble code.
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. 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 C1551, C1552, C1553, C1554, C1555 or C1608 set?
YES: Replace steering wheel sensor.
NO: The procedure is complete.
DTC U1073: BUS OFF TROUBLE JUDGMENT This code is stored when the steering wheel sensor has ceased the CAN
communication (bus off). Then, if a penalty mode is entered after approximately
five minutes, regular data transmission will be cancelled. TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
Damaged wiring harness or connector Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU)
DIAGNOSIS Required Special Tools: CAUTION:
If DTC U1073 is set in the steering wheel sensor,
always diagnose the CAN main bus line. If there
is any fault in the CAN bus lines, an incorrect
DTC may be set. Whenever the ECU is replaced, ensure that the
communication circuit is normal.
CAUTION: If DTC U1073 has been set, TCL/ASC-ECU related
DTC C1506 is also set. After DTC U1073 has been
diagnosed, don't forget to erase DTC C1506.
