IPDM-E BRANCH LINE CIRCUIT

Diagnosis Procedure

INFOID:0000000010715321

1.

CHECK CONNECTOR

1.

Turn the ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Check the terminals and connectors of the IPDM E/R for damage, bend and loose connection (unit side
and connector side).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

1.

Disconnect the connector of IPDM E/R.

2.

Check the resistance between the IPDM E/R harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the IPDM E/R branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the IPDM E/R. Refer to 

PCS-59, "Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the IPDM E/R. Refer to 

PCS-60, "Removal and Installation"

.

YES (Past error)>>Error was detected in the IPDM E/R branch line.
NO

>> Repair the power supply and the ground circuit.

1.

CHECK CONNECTOR

1.

Turn the ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Check the following terminals and connectors for damage, bend and loose connection (unit side and con-
nector side).

-

TCM

-

IPDM E/R

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1.

Disconnect the following harness connectors.

-

TCM

-

IPDM E/R

2.

Check the continuity between the TCM harness connector and the IPDM E/R harness connector.

-

Except for R9M engine models

-

R9M engine models

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the branch line between the TCM and IPDM E/R.

3.

CHECK IPDM E/R (OPEN CIRCUIT)

Check the continuity between the IPDM E/R terminals.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Replace the IPDM E/R.

4.

CHECK HARNESS FOR OPEN CIRCUIT

Check the resistance between the IPDM E/R harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 5.

NO

>> Repair the IPDM E/R branch line.

5.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the TCM. Refer to 

TM-388, "Diagnosis Procedure"

(RE0F10D models) or 

TM-652, "Diagnosis Procedure"

 (RE0F10G models).

Is the inspection result normal?

YES (Present error)>>Replace the TCM. Refer to 

TM-415, "Removal and Installation"

 (RE0F10D models) or

TM-676, "Removal and Installation"

 (RE0F10G models).

YES (Past error)>>Error was detected in the TCM branch line.
NO

>> Repair the power supply and the ground circuit.
