COMPONENT DIAGNOSIS

DTC U1000 CAN COMMUNICATION LINE

Description

INFOID:0000000001694277

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.

On Board Diagnosis Logic

INFOID:0000000001694278

• This is an OBD self-diagnostic item.
• Diagnostic trouble code “U1000 CAN COMM CIRCUIT” with CONSULT-III or 12th judgement flicker without

CONSULT-III is detected when TCM cannot communicate to other control units.

Possible Cause

INFOID:0000000001694279

Harness or connector
(CAN communication line is open or shorted.)

DTC Confirmation Procedure

INFOID:0000000001694280

NOTE:
If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at least 10
seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.

 WITH CONSULT-III

1.

Turn ignition switch ON.

2.

Select “DATA MONITOR” mode for “A/T” with CONSULT-III.

3.

Touch “START”.

4.

Wait at least 6 seconds or start engine and wait for at least 6 seconds.

5.

If DTC is detected, go to 

TM-43, "Diagnosis Procedure"

.

 WITH GST

Follow the procedure “WITH CONSULT-III”.

 WITHOUT CONSULT-III

1.

Turn ignition switch ON.

2.

Wait at least 6 seconds or start engine and wait at least 6 seconds.

3.

Perform self-diagnosis. Refer to 

TM-38, "Diagnosis Procedure without CONSULT-III"

.

4.

If DTC is detected, go to 

TM-43, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000001694282

DTC P0705 PARK/NEUTRAL POSITION (PNP) SWITCH

DTC P0705 PARK/NEUTRAL POSITION (PNP) SWITCH

Description

INFOID:0000000001694283

• The PNP switch assembly includes a transaxle range switch.
• The transaxle range switch detects the selector lever position and sends a signal to the TCM.

CONSULT-III Reference Value in Data Monitor Mode

INFOID:0000000001694284

Remarks: Specification data are reference values.

On Board Diagnosis Logic

INFOID:0000000001694285

• This is an OBD self-diagnostic item.
• Diagnostic trouble code “P0705 PNP SW/CIRC” with CONSULT-III is detected when TCM does not receive

the correct voltage signal from the switch based on the gear position.

Possible Cause

INFOID:0000000001694286

• Harness or connectors

[The PNP switch circuit is open or shorted.]

• PNP switch

DTC Confirmation Procedure

INFOID:0000000001694287

CAUTION:

• Always drive vehicle at a safe speed.
• If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at

least 10 seconds before continuing.

After the repair, perform the following procedure to confirm the malfunction is eliminated.

 WITH CONSULT-III

1.

Turn ignition switch ON. (Do not start engine.)

2.

Select “DATA MONITOR” mode for “A/T” with CONSULT-III.

3.

Touch “START”.

4.

Start engine and maintain the following conditions for at least 5 consecutive seconds.
VEHICLE SPEED: 10 km/h (6 MPH) or more
THROTTLE POSI: More than 1.0/8
SLCT LVR POSI: “D” position

5.

If the check result is NG, go to 

TM-44, "Diagnosis Procedure"

.

 WITH GST

Follow the procedure “WITH CONSULT-III”.
