DIAGNOSIS
STEP 1. MUT-III CAN bus diagnostics
CAUTION
Before connecting or disconnecting the MUT-III,
turn the ignition switch to the "LOCK" (OFF)
position.
(1) Connect MUT-III to the 16-pin diagnosis
connector.
(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 check result normal?
YES :
Go to Step 3.
NO :
Repair the CAN bus line (Refer to GROUP

). Then go to Step 2.
STEP 2. Check whether the diagnosis code is
reset.
CAUTION
Before connecting or disconnecting the MUT-III,
turn the ignition switch to the "LOCK" (OFF)
position.
(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.
(5) Check if the diagnosis code is set.
(6) Turn the ignition switch to the "LOCK" (OFF)
position.
Q: Is code No.C1377 set?
YES :
Go to Step 3.
NO :
The procedure is complete.

(1) Disconnect TCL/ASC-ECU connector A-04 and
G and yaw rate sensor connector C-117
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between the relevant signal
terminals 2, 3 and earth.
OK: Less than 1V
Q: Is the check result normal?
YES :
Go to Step 4.
NO :
Check the harness wire between
TCL/ASC-ECU and the G and yaw rate
sensor for short to power supply. Repair if
necessary, and then go to Step 8.
