Subject: Re: 86-89 Digital Instrument Cluster "OD" light by tequilaboy on 2012/12/13 19:26:43 First test failed. Bit 5 clears as expected with changes, but OD indicator still on. Must be another bit... Current thinking is that $0036 bit 1 is controlling the OD indicator, and bit 7 is controlling shift light. Still need to verify. C6D9: FDB $0036 ; 54, MODE WORD 2 ; b0 1 = CARS ACTIVE ; b1 1 = MALF 14 OR 15 THIS START UP ; b2 1 = REFERENCE PULSE OCCURRED ; b3 1 = IN ALDL MODE 8192 LOCKED IN AND MODE 4 ; b4 1 = DIAGNOSTIC SWITCH IN DIAG POSITION ; b5 1 = DIAGNOSTIC SWITCH IN ALDL POSITION ; b6 1 = HIGH BATTERY VOLTAGE-DISABLE MCU SOL DISABLE ; b7 1 = SHIFT LIGHT ON ; ;----------------------------- |
