(TCS)—
DTC DETECTING CONDITION:

Two consecutive trips with fault
TROUBLE SYMPTOM:

No operation TCS

TCS warning light remains illuminated.
1.Check if the vehicle is equipped with TCS.

2.Check output signal from ECM.
3.Check harness connector.
4.Check ECM connector.
CAUTION:
After repair or replacement of faulty parts, conduct
CLEAR MEMORY and INSPECTION MODES. [T3D0] and [T3E0].>

When DTC P1104 is on display, check engine cooling sys-
tem.
CAUTION:
After repair or replacement of faulty parts, conduct
CLEAR MEMORY and INSPECTION MODES. [T3D0] and [T3E0].>
NOTE:
If the vehicle, with the engine idling, is placed very close to
a wall or another vehicle, preventing normal cooling
function, the OBD system may detect malfunction.

1.CHECK HARNESS CONNECTOR BETWEEN
TCM AND CCM.
1) Turn ignition switch to OFF.
2) Disconnect connectors from TCM and CCM.
3) Measure resistance of harness connector between
TCM and CCM.
: Connector & terminal
(B56) No. 3—(B94) No. 3 / 10Ω, or less
: Repair open circuit of harness between TCM con-
nector and CCM connector.
: Go to next step.
OBD0515A
4) Measure resistance of harness connector between
TCM and body.
: Connector & terminal
(B56) No. 3—Body / 1 MΩ, or more
: Repair short circuit of harness between TCM con-
nector and CCM connector.
: Go to step 2.

(ATDIAG)—
DTC DETECTING CONDITION:

Two consecutive trips with fault
1.Check transmission type.
AT
MT
Check AT/MT identification circuit.

2.Check harness.
3.Check harness.
CAUTION:

BN:—AT/MT IDENTIFICATION CIRCUIT
MALFUNCTION [MT VEHICLES]—
DESCRIPTION:
The circuit allows the ECM to identify the vehicle as an AT
or MT vehicle.
1.Check harness connector.
CAUTION:
After repair or replacement of faulty parts, conduct
CLEAR MEMORY and INSPECTION MODES. [T3D0] and [T3E0].>

1
CHECK HARNESS CONNECTOR.
1) Turn ignition switch to ON.
2) Measure voltage between ECM and body.
: Connector & terminal
(B84) No. 50—Body / 2 V, or more
: Repair open circuit of harness between ECM con-
nector and body.
: Confirm good connection at ECM connector.
