Subaru Legacy Service Manual: Inspection

CAUTION:

When wiping dirt off of the glass to avoid heat wire damage, be careful of the following.

Use a dry and soft cloth.

Move the cloth along the heat wire.

Inspection method of antenna, it is different from printing pattern of antenna.

TYPE-A

Printing pattern of grid

TYPE-B

Printing pattern of straight

1. TYPE-A

1. Prepare the extension harness (A), (B).

(A)

Attach the flat terminals (male and female) to both ends of the harness of approx. 2 m (6.56 ft) length (electrical wire unit dimensions: approx. 2.0 mm2 (0.0032 sq in)).

(B)

Attach the flat terminal (female) to one side of the harness, another side to twist the harness of approx. 2 m (6.56 ft) length (electrical wire unit dimensions: approx. 2.0 mm2 (0.0032 sq in)).

2. Disconnect the ground terminal from battery sensor. NOTE

3. Connect the extension harness (A) to rear defogger harness (power supply side) terminal and antenna terminal.

4. Connect the extension harness (B) to rear defogger harness (ground side) terminal.

5. Fasten the another side of extension harness (B) to end of antenna pattern of grid with tape.

6. Connect the ground terminal to battery sensor. NOTE

7. Turn the ignition to ON.

8. Turn the rear defogger switch to ON.

9. Wrap a piece of aluminum foil around the tip of tester probe and press foil against antenna wire with your finger.

(A)

Tester probe

(B)

Aluminum foil

(C)

Antenna wire

10. Measure the voltage around an antenna wire (a) and (b).

Measured voltage value

Criteria

(a)

Approx. 3 V (standard value)

Normal

Approx. 6 V or 0 V

Open

(b)

Approx. 9 V (standard value)

Normal

Approx. 12 V or 6 V

Open

NOTE:

Measuring point (a)

If the measured value is 6 V, heat wire is open between antenna wire center and positive (+) side of probe.

If it is 0 V, the circuit is open between antenna wire center and ground.

Measuring point (b)

If the measured value is 12 V, heat wire is open between antenna wire center and positive (+) side of probe.

If it is 6 V, the circuit is open between antenna wire center and ground.

11. Fasten the voltmeter positive (+) side and negative (−) side to end of open harness positive side of step 12).

12. Search a point the voltage changes from 0 V, and move the negative (−) probe along antenna wire slowly.

13. Repair the antenna wire if the place of the open circuit is identified. Antenna > REPAIR

2. TYPE-B

Measure the resistance between the antenna terminal and each antenna wire.

1. Disconnect the ground terminal from battery sensor. NOTE

2. Wrap a piece of aluminum foil around the tip of probe and press foil against antenna wire with your finger.

(A)

Tester probe

(B)

Aluminum foil

(C)

Antenna wire

3. To locate the broken point, move the probe along antenna wire.

NOTE:

If an antenna wire is OK, resistance will be less than 20 -.

If an antenna wire is broken, resistance will be more than 1 M-.

4. Connect the ground terminal to battery sensor. NOTE

5. Repair the antenna wire if the place of the open circuit is identified. Antenna > REPAIR
