2004 MITSUBISHI ENDEAVOR light

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.

CIRCUIT OPERATION
ABS/TCL-ECU < FWD > or TCL/ASC-ECU < AWD > send the illumination
signal of "TCL OFF" indicator light and TCL work indicator light to the
combination meter via the CAN communication. ABS/TCL-ECU < FWD > or TCL/ASC-ECU < AWD > operates the "TCL
OFF" indicator light and the TCL work indicator light for three seconds after
the ignition switch is turned "ON" position for bulb check.
COMMENT This may be caused by faults in the CAN bus line, the combination meter or the
ABS/TCL-ECU < FWD > or TCL/ASC-ECU < AWD >. TROUBLESHOOTING HINTS
