IPDM-E BRANCH LINE CIRCUIT

Diagnosis Procedure

INFOID:0000000012200553

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-36, "Diagnosis Procedure"

.

Is the inspection result normal?

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

PCS-37, "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.

Diagnosis Procedure

INFOID:0000000012200554

WARNING:

• Before servicing, turn ignition switch OFF, disconnect battery negative terminal, and wait 3 minutes

or more. (To discharge backup capacitor.)

• Never use unspecified tester or other measuring device.

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 air bag diagnosis sensor unit for damage, bend and loose con-

nection (unit side and connector side).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace the main harness.

2.

CHECK AIR BAG DIAGNOSIS SENSOR UNIT

Check the air bag diagnosis sensor unit. Refer to 

SRC-29, "Work Flow"

.

Is the inspection result normal?

YES

>> Replace the main harness.

NO

>> Replace parts whose air bag system has a malfunction.

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 A/C auto amp. 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 A/C auto amp.

2. Check the resistance between the A/C auto amp. harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the A/C auto amp. branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the A/C auto amp. Refer to 

HAC-75, "A/C AUTO AMP. :

Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the A/C auto amp. Refer to 

HAC-93, "Removal and Installation"

.

YES (Past error)>>Error was detected in the A/C auto amp. branch line.

NO

>> Repair the power supply and the ground circuit.
