      Tester Connection Condition Specified Condition I135-26 (SIG-) - S12-16 (GND3) Always Below 1 Ω I135-26 (SIG-) - Body ground Always 10 kΩ or higher

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

4. REPLACE DCM (TELEMATICS TRANSCEIVER)

   
   

   1. Replace the DCM (Telematics Transceiver) Click here.

      Note

      
      

      • The engine switch must be off.

      • Do not swap the DCM (Telematics Transceiver) with one from another vehicle.

5. READ VALUE USING TECHSTREAM (MANUAL (SOS) SWITCH OPERATION)

   
   

   1. Turn the engine switch off.

   2. Connect the Techstream to the DLC3.

   3. Turn the engine switch on (IG) and wait for 10 seconds.

   4. Turn the Techstream on.

   5. Enter the following menus: Body Electrical / Telematics / Data List.

   6. Check that the manual (SOS) switch condition observed on the Techstream changes according to manual (SOS) switch operation.

      Telematics

      Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
      Emergency Switch	Manual (SOS) switch / OFF or ON	OFF: Manual (SOS) switch not pressed	-
      		ON: Manual (SOS) switch pressed*	-

      
      

      • *: Pressing the manual (SOS) switch will connect to the call center.

      Result
      Result Proceed to Techstream display changes when turning the manual (SOS) switch ON/OFF. A Techstream display does not change when turning the manual (SOS) switch ON/OFF. B
