INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC

(a) Turn the ignition switch off.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch to ON and wait for 10 seconds.

(d) Turn the Techstream on.

(e) Perform "HEALTH CHECK" and check current DTC Health Check.

Result





B -- READ VALUE USING TECHSTREAM (MANUAL (SOS) SWITCH OPERATION)
A -- Continue to next step.

2. INSPECT ROOF CONSOLE BOX ASSEMBLY (MANUAL (SOS) SWITCH)

(a) Disconnect the T5 roof console box assembly connector.





(b) 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. REPLACE DCM (TELEMATICS TRANSCEIVER)

(a) Replace the DCM (Telematics Transceiver) Removal.

NOTICE:
* The ignition switch must be off.
* Do not swap the DCM (Telematics Transceiver) with one from another vehicle.

NEXT -- PERFORM DCM ACTIVATION DCM Activation

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

(a) Turn the ignition switch off.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch to ON and wait for 10 seconds.

(d) Turn the Techstream on.

(e) Enter the following menus: Body Electrical / Telematics / Data List.

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