U1000 CAN COMM CIRCUIT

DTC/CIRCUIT DIAGNOSIS

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000005513962

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 and CAN-L) allowing a high rate of information transmission with
less wiring. Each control unit transmits/receives data but selectively reads required data only.

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

NOTE:
Immediately after performing any “DTC CONFIRMATION PROCEDURE”, always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.

1.

CHECK DTC DETECTION

With CONSULT-III

1.

Turn ignition switch ON.

2.

Start engine and wait for at least 6 seconds.

3.

Perform “Self Diagnostic Results” in “TRANSMISSION”.

With GST

Follow the procedure “With CONSULT-III”.

Is “U1000” detected?

YES

>> Go to 

TM-40, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to 

GI-39, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000005513964

Go to 

LAN-27, "CAN System Specification Chart"

.

P0615 STARTER RELAY

Description

INFOID:0000000005513965

• TCM controls starter relay in IPDM E/R.
• TCM switches starter relay ON at “P” or “N” position and allows to cranking engine. 
• Then it prohibits cranking other than at “P” or “N” position.

.

Diagnosis Procedure

INFOID:0000000005513967

1.

CHECK STARTER RELAY SIGNAL

1.

Turn ignition switch OFF.

2.

Disconnect IPDM E/R connector.

3.

Turn ignition switch ON.

4.

Check voltage between IPDM E/R vehicle side harness connector terminal and ground.

Is the inspection result normal?

YES

>> Check starter relay and starter control relay. Refer to 

PCS-10, "Diagnosis Description"

.

NO

>> GO TO 2.

2.

CHECK HARNESS BETWEEN TCM AND IPDM E/R (PART 1)

1.

Turn ignition switch OFF.

2.

Disconnect TCM connector.

3.

Check continuity between TCM vehicle side harness connector terminal and IPDM E/R vehicle side har-
ness connector terminal.

Is the inspection result normal?

Starter Relay Circuit

If this signal is ON other than in “P” or “N” po-
sition, this is judged to be a malfunction.
(And if it is OFF in “P” or “N” position, this too 
is judged to be a malfunction.)

• Harness or connectors

(Starter relay and TCM circuit is open or 
shorted.)
