COMPONENT DIAGNOSIS

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000003848946

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” mode for “TRANSMISSION”.

With GST

Follow the procedure “With CONSULT-III”.

Is “U1000 CAN COMM CIRCUIT” detected?

YES

>> Go to

TM-41, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to

GI-35, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000003848948

1.

CHECK CAN COMMUNICATION CIRCUIT

With CONSULT-III

1.

Turn ignition switch ON and start engine.

2.

Perform “Self-Diagnostic Results” mode for “TRANSMISSION”.

Is “U1000 CAN COMM CIRCUIT” indicated?

YES

>> Go to LAN section. Refer to

LAN-22, "CAN System Specification Chart"

.

NO

>> Check intermittent incident. Refer to

GI-35, "Intermittent Incident"

.

P0615 START SIGNAL

Description

INFOID:0000000003848949

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

DTC CONFIRMATION PROCEDURE

CAUTION:

Always drive vehicle at a safe speed.
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.

Perform “Self-Diagnostic Results” mode for “TRANSMISSION”.

Is “P0615 STARTER RELAY/CIRC” detected?

YES

>> Go to

TM-42, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to

GI-35, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000003848951

1.

CHECK STARTER RELAY SIGNAL

1.

Turn ignition switch ON.

2.

Disconnect IPDM E/R harness connector.

3.

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

STR-10, "Wiring Diagram - STARTING SYS-

TEM -"

.

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.

STARTER RELAY/CIRC

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.)
