Pinpoint Test E: The Battery Saver Does Not Deactivate After Time-out

Refer to Wiring Diagram Set 89, Interior Lamps for schematic and connector information. Diagrams By Number

Normal Operation

The Generic Electronic Module (GEM) provides a battery saver function. The battery saver function provides automatic shutoff of the interior lamps after 30 minutes has elapsed in order to save battery power.

- DTC B1315 (Battery Saver Relay Coil Circuit Short To Battery) - a continuous DTC that sets when the GEM detects a short to voltage from the battery saver output circuit.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- GEM



PINPOINT TEST E: THE BATTERY SAVER DOES NOT DEACTIVATE AFTER TIME-OUT

-------------------------------------------------
E1 CHECK THE BATTERY SAVER OUTPUT CIRCUIT FOR A SHORT TO VOLTAGE


- Ignition OFF.
- Disconnect: GEM C201d.
- Ignition ON.
- Place the front interior lamp control switch in the ON position.
- Do the interior lamps illuminate?

Yes
REPAIR the battery saver output circuit for a short to voltage. TEST the system for normal operation.

No
GO to E2.

-------------------------------------------------
E2 CHECK FOR CORRECT GEM OPERATION


- Disconnect all the GEM connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the GEM connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?

Yes
INSTALL a new GEM. REFER to Body Control Systems. TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
