   NO 

   Go to step 3.

3. Open wire check (SH(SAT/TER) line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Roof antenna connector B (2P): disconnected
   Test point 1	Roof antenna connector B (2P) (male terminals) No. 2:
   Test point 2	Body ground

   Is there continuity?

   YES 

   The SH(SAT/TER) wire is not open. Go to step 4.

   NO 

   There is an open in the wire. Replace the affected antenna lead.

4. Shorted wire check (SAT/TER line)

   -1. Disconnect the following connector.

   Audio unit connector H (2P)

   -2. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Roof antenna connector B (2P): disconnected
   	Audio unit connector H (2P): disconnected
   Test point 1	Audio unit connector H (2P) No. 1
   Test point 2	Body ground

   Is there continuity?

   YES 

   There is a short to body ground in the wire. Replace the affected antenna lead.

   NO 

   The SAT/TER wire is not shorted to ground. Go to step 5.

5. Shorted wire check (SAT/TER line to SH(SAT/TER) line)

   -1. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Roof antenna connector B (2P): disconnected
   	Audio unit connector H (2P): disconnected
   Test point 1	Audio unit connector H (2P) No. 1
   Test point 2	Audio unit connector H (2P) No. 2

   Is there continuity?

   YES 

   There is a short in the wire. Replace the affected antenna lead.

   NO 

   The SAT/TER wire is not shorted to SH(SAT/TER) wire. Go to step 6.

6. Open wire check (SAT/TER line)

   -1. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Roof antenna connector B (2P): disconnected
   	Audio unit connector H (2P): disconnected
   Test point 1	Audio unit connector H (2P) No. 1
   Test point 2	Roof antenna connector B (2P) (male terminals) No. 1:
