·

Before replacing the telematics transceiver, refer to Service Bulletin.



HINT:

Inspect the fuses and relays related to this system before inspecting the suspected areas below.


PROCEDURE

1.CHECK HARNESS AND CONNECTOR (MAP LIGHT ASSEMBLY POWER SOURCE)
a.

Disconnect the I200 telematics transceiver connector.


b.

Disconnect the T6 map light assembly connector.


c.

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

Standard Resistance:
Tester Connection Condition Specified Condition
I200-3 (SIG-) - T6-19 (GND3) Always Below 1 Ω
I200-3 (SIG-) or T6-19 (GND3) - Body ground Always 10 kΩ or higher



d.

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

Standard Voltage:
Tester Connection Switch Condition Specified Condition
T6-8 (RRID) - Body Ground Ignition switch ON 11 to 14 V



Result:
Proceed to
OK
NG



OK

(Map Light Assembly)


Connect a positive (+) lead from the batteries to terminal 8 (RRID), and a negative (-) lead to terminal 19 (GND3) of the map light assembly connector.


d.

Check if the emergency call switch illumination comes on.

OK:

The emergency call switch illumination comes on.



Result:
Proceed to
OK
NG



OK
