Woodcliff Lake, NJ April 1990 Service Engineering
SUBJECT: Service Interval Indicator I (9 LEDS)
MODELS: E30 (prior to 1/86 production)
Situation: For improved reliability, improvements have been made to the Service interval indicator processor/circuit board. These improvements are:
^ 2 Lithium buffer batteries - greater reliability, (versus NiCad) longer storage time.
^ Parallel circuit for - buffer batteries required buffer batteries only if main battery
is disconnected.
^ Activation switch - prevents drain on buffer
(contact bridge) batteries before placement
into vehicle.
^ FR4 (fiber-reinforced) - provides greater strength, board material reliability of circuitry.
^ Lacquering of all - prevents circuit migration, components self-discharge.
Installation
Note: Before inserting the circuit board into the cluster housing, the contact bridge must be moved to the "ON" position (see drawings) to activate the Service Interval Indicator.
