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 Multifunction Electronic Modules Service and Repair. 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.
