TELEMATICS SYSTEM (DIAGNOSTICS) > Diagnostic Procedure with Diagnostic Trouble Code (DTC)
DTC B2A09 I-CALL BUTTON CIRCUIT
Diagnosis start condition:
When ignition switch is ON.
DTC detecting condition:
The following conditions occur for at least 50 ms.
• i-button impedance is more than 10 k?.
• i-button is stuck for at least 60 seconds.
Trouble symptom:
• i-Call function cannot be used.
• RED LED illuminates.
Wiring diagram:
NOTE:
For the coupling connector, refer to “WIRING SYSTEM”.

STEP | CHECK | YES | NO |
1.CHECK DTC.
Read the DTC. Diagnostic Code(s) Display">
Is DTC B2A09 displayed? (Current malfunction)
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2A09 I-CALL BUTTON CIRCUIT">Go to Step 2.
Even if DTC is displayed, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.
In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.
2.CHECK HARNESS (OPEN CIRCUIT).
1) Turn the ignition switch to OFF.
2) Disconnect the telematics button connector.
3) Disconnect the DCM connector.
4) Measure the resistance between telematics button connector and DCM connector.
Connector & terminal
(i270) No. 4 — (AD2) No. 3:
(AD2) No. 1 — Chassis ground:
Is the resistance 1 ? or less?
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2A09 I-CALL BUTTON CIRCUIT">Go to Step 3.
Repair or replace the open circuit of harness.
3.CHECK HARNESS (GROUND SHORT CIRCUIT).
Measure the resistance between DCM connector and chassis ground.
Connector & terminal
(i270) No. 4 — Chassis ground:
Is the resistance 1 M? or more?
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2A09 I-CALL BUTTON CIRCUIT">Go to Step 4.
Repair or replace the short circuit of the harness.
4.CHECK THE CONNECTOR (SHORT CIRCUIT TO POWER SUPPLY).
Measure the voltage between DCM connector and chassis ground.
Connector & terminal
(i270) No. 4 (+) — Chassis ground (−):
(AD2) No. 1 (+) — Chassis ground (−):
Is the voltage less than 1 V?
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2A09 I-CALL BUTTON CIRCUIT">Go to Step 5.
Repair or replace the short circuit of the harness.
5.CHECK I-BUTTON.
Measure the resistance of the i-button unit.
Terminals
No. 3 — No. 1:
Is the resistance 1 ? or less when i-button is ON, and 1.6 (±5%) k? or more when i-button is OFF?
