NG | REPLACE TELEPHONE ANTENNA (NAVIGATION ANTENNA ASSEMBLY) |
|
3. | INSPECT TELEPHONE ANTENNA CORD (ANTENNA CORD SUB-ASSEMBLY) |
(a) Disconnect the antenna connector from the navigation antenna assembly. |
|
(b) Disconnect the antenna connector from the wire harness.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
A-4 - I169-4 (TEL) | Always | Below 1 Ω |
A-4a - I169-4a | Always | Below 1 Ω |
A-4 - Body ground | Always | 10 kΩ or higher |
NG | REPLACE TELEPHONE ANTENNA CORD (ANTENNA CORD SUB-ASSEMBLY) |
|
4. | CHECK HARNESS AND CONNECTOR (ANTENNA CORD SUB-ASSEMBLY - DCM [TELEMATICS TRANSCEIVER]) |
(a) Disconnect the antenna cord sub-assembly connector. |
|
(b) Disconnect the DCM (telematics transceiver) connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
I169-4 (TEL) - I186-1 (TEL [ANT3]) | Always | Below 1 Ω |
I169-4a - I169-1a | Always | Below 1 Ω |
I169-4 (TEL) - Body ground | Always | 10 kΩ or higher |
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
5. | CHECK TELEPHONE ANTENNA (NAVIGATION ANTENNA ASSEMBLY) |
(a) Replace the telephone antenna (navigation antenna assembly) with a known good one.
Click here
(b) Clear the DTCs.
Click here
Body Electrical > Telematics > Clear DTCs(c) Recheck for DTCs and check that no DTCs are output.
Click here
Body Electrical > Telematics > Trouble CodesOK:
No DTCs are output.
OK | END (TELEPHONE ANTENNA [NAVIGATION ANTENNA ASSEMBLY] IS DEFECTIVE) |
|
6. | REPLACE DCM (TELEMATICS TRANSCEIVER) |
(a) Replace the DCM (telematics transceiver).
