## Tape Retract Module Malfunction Early Design

Entertainment Components
Power and Ground Distribution (Early Design)

### Circuit Description

The Video Cassette Player (VCP) plays pre-recorded VHS cassettes. The VCP voltage supply is controlled by the Tape Retract Module (TRM). The TRM supplies the VCP with voltage from the fuse block when the ignition is on and the video display screen is pulled down in the viewing position. When the ignition switch is turned off, the IGN input to the TRM is deenergized and the TRM then removes voltage supply momentarily to the VCP. The TRM turns off momentarily causing the VCP to turn off. Then, the TRM restores the voltage back to the VCP for 12 seconds,to allow the VCP to retract the cassette tape from the playback head, thus preventing cassette damage. Note that the "cassette-in" indicator lamp in the VCP turns on during the 12 second period when the VHS tape is unloaded in the VCP.

### Diagnostic Aids

• | Check for a faulty TRM.

• | An intermittent failure may be very difficult to detect and to diagnose accurately. Faulty electrical connections or wiring causes most intermittent problems. When an intermittent condition is suspected, check the suspected circuits for the following conditions:

- | Poor mating of connector halves or backed out terminals.

- | Improperly formed or damaged terminals.

- | Wire chafing.

- | Poor wire to terminal connections.

- | Dirty or corroded terminals.

- | Damage to connector bodies.

- | Wire broken inside the insulation.

### Test Description

The number(s) below refer to the step number(s) on the diagnostic table.

1. Verifies repairs made to the VES.

Step | Action | Value(s) | Yes | No
--- | --- | --- | --- | ---
1 | Test for a poor connection at the Tape Retract Module (TRM). If the connection is OK, then replace the TRM. Refer to Tape Retract Module Replacement . Is the repair complete? | -- | Go to Step 2 | --
2 |

1. Turn the ignition switch off.
2. Reconnect the connectors or the components that were previously removed.
3. Verify that the VES operates properly.

Does the VES operate normally?
