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 (Generic Electronic Module) 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 (Generic Electronic Module)

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 (Generic Electronic Module) 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 (Generic Electronic Module) OPERATION

- Disconnect all the GEM (Generic Electronic Module) connectors.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect all the GEM (Generic Electronic Module) 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 (Generic Electronic Module). 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.
