•
Ignition switch connector C-307
Check the connectors, for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.
Q: Is the check result normal?
YES :
An open or short circuit may be present in
the power supply line to the TCL/ASC-ECU.
Repair the wiring harness between
TCL/ASC-ECU connector A-04 terminal 32
and ignition switch connector C-307
terminal 2. Then go to Step 8.
NO :
Repair or replace the damaged
component(s). Then go to Step 8.

STEP 7. Check whether the diagnosis code is
reset.
CAUTION
Before connecting or disconnecting the MUT-III,
turn the ignition switch to the "LOCK" (OFF)
position.
Check again if the diagnosis code is set.
(1) Turn the ignition switch to the "ON" position.
(2) Erase the diagnosis code.
(3) Turn the ignition switch to the "LOCK" (OFF)
position.
(4) Turn the ignition switch to the "ON" position.

Code No.C1864: Sensor cluster power supply abnormality
CAUTION
If there is any problem in the CAN bus lines, an
incorrect diagnosis code may be set. Prior to this
diagnosis, diagnose the CAN bus lines.
OPERATION
• The G and yaw late sensor is energized by the
TCL/ASC-ECU and the G and yaw late sensor
terminal 1.
• The G and yaw late sensor output signal is sent
to the TCL/ASC-ECU via the CAN bus line.
DIAGNOSIS CODE SET CONDITIONS
These codes are set when the power supply to the G
and yaw late sensor is not normal.
PROBABLE CAUSES
• Malfunction of the G and yaw late sensor
• Damaged wiring harness or connector
• Malfunction of the hydraulic unit (integrated with
TCL/ASC-ECU)
