ok mech. , join a real Saturn forum.?
rule #1 is fuse first. all must be good.
what does gauges dead mean sure ,meters dead but is the cluster dead, IP cluster 100% dead, and CEL lamp self test key on dead.>?
scan it yet? that is rule 2 (assumes battery is good /charged)
scan it but DLC OBD2 Pin 16 needs 12vdc and fuse blow there scan tools are born dead. back to rule #1 again.
does engine crank and run and drive.?
do head lamps work?
does the radio work. ?
heater blower blows.?
and is the ODOM dead./?????????/ if comm's or fuse dead)
new battery not connected backwards now or before.
many electronics blow up backwards, see some do have a diode on the VCC/VDD rails in electronics to stop that but some do not.!
to diagnose any car made we take note of all things
good , bad or ugly seen. all facts matter and reduce the testing needed.
all matter, even head lamps work key on or off.
many clusters now are on a CAN bus, network BINGO HERE>
, ONE OF HE FIRST IN USA.
USA spec, car or NOT. (gm exports cars ww)
I will now punch up L300 in the service manual just for you
gauges.?
speedo dead
tachmeter ded
fuel dead
engine temp, dead?
ODOMETER DEAD that too is meter but proves power and can bus not dead if works, does this work ?
here is the FSM page words for how that all works
"The instrument cluster receives information via the Class 2 serial data link from the 4 cylinder (L61) Body Control Module (BCM), the powertrain control module (PCM), and the sensing and diagnostic module (SDM). On V6 (L81) engine applications, the information from the engine control module (ECM) and the transaxle control module (TCM) is sent to the BCM over the CAN serial data link where it is converted to a Class 2 message and sent to the cluster. The information from the electronic brake/traction control module (EBTCM) is sent to the BCM, where it is converted into a Class 2 message and sent to the cluster."
NOW THE NITTY GRITTY FACTS HARD
ign1 FUSE NOT BLOW OR IP IS DEAD, ZERO POWER TO IT.
the can bus nor serial class 2 bus must not be dead.
or IP goes dead.
all needle meters go dead too. like that or fuse IGN1 dead.
or PCM /ECU nor and more.
the whole IP runs off a network. real. and very modern that year.
IGN1 fuse must not be blown.
