Airbag System (for Hatchback without VSC)

SUPPLEMENTAL RESTRAINT SYSTEMS: AIRBAG SYSTEM (for Hatchback without VSC): TC and CG Terminal Circuit
- TC and CG Terminal Circuit

DESCRIPTION

DTC output mode is set by connecting terminals TC and CG of the DLC3.

The DTCs are displayed by blinking the SRS warning light.

HINT
* Make sure that DTCs which relate to the CAN communication system are not output. If any of these DTCs are output, check the CAN communication system Diagnosis System (from 07/2011).
* When a warning light keeps blinking, a short to ground in the wiring of terminal TC of the DLC3 or an internal ground short in an ECU is suspected.
* The DTC output mode signal is transmitted through the CAN to each ECU including the airbag sensor assembly. Thus if no systems enter DTC output mode, the ECM may have a malfunction.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (DLC3 - ECM)

(a) Turn the ignition switch off.

(b) Disconnect the connector from the ECM.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (CG OF DLC3 - BODY GROUND)

(a) Measure the resistance according to the value(s) in the table below.





Standard Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (TC OF ECM)

(a) Measure the resistance according to the value(s) in the table below.





Standard Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

4. CHECK ECM

(a) Replace the ECM Removal (from 07/2011).

(b) Check for DTCs of the ECM.

Result





B -- GO TO INSPECTION PROCEDURE OF DTC OUTPUT Airbag System (for Hatchback without VSC)

C -- REPLACE AIRBAG SENSOR ASSEMBLY Removal (from 07/2011)

A -- END (ECM WAS DEFECTIVE)
