Battery Saver Relay The following components are under the control of the battery saver relay:Delayed accessory relay.Overhead interior lamp with map lamps.Underhood lamp switch.Glove box lamp switch.Overhead interior lamp switch.Intior lamp coil.The battery saver relay becomes active (relay coil is energized) when the GEM is in awake mode and is deactivated (relay coil is de-energized) in sleep mode.The battery saver will remain active until the ignition state is not ACC or RUN and 45 minutes have passed since last active input. At that time, the relay will be deactivated and power to the above circuits will terminate.Five minutes after the battery saver relay has become deactivated, the GEM will go into a lower power state known as sleep mode. In the sleep mode, the GEM will deactivate all outputs and will monitor select inputs.Logical characteristics of the Gem battery saver mode are as follows:Feature Inputs: Sleep/Awake mode status.Feature Outputs: Battery saver relay control (Open circuit in sleep mode, grounded when awake).
Ignition Switch Positions The position of the ignition switch is very important to proper GEM operation. Often times, erratic or unexpected operation can be traced to problems on these GEM inputs. The following is a brief description of five ignition switch positions.When the ignition switch is in the RUN position, battery voltage should be present at the GEM/CTM RUN and RUN/ACC input terminals When the ignition switch is in the ACC position, battery voltage should be present at the GEM/CTM RUN/ACC input terminal only.When the ignition switch is in the START position, battery voltage should be present at the GEM/CTM start/clutch depressed input. The 45 minute time is in part of the GEM module.The GEM module does not have an OFF or LOCK Switch State input. The GEM will assume the OFF or LOCK position when there are no RUN, ACC, or START signals present.GEM Features and Functions
