SCI TRANSMIT CIRCUIT OPEN
With the ignition off.
Measure the resistance of the SCI Transmit circuit from the SLA har-
ness connector to the DLC.
Is the resistance below 5.0 ohms?
Yes >> Replace the Shift Lever Assembly. (Refer to 21 - TRANS-
MISSION/TRANSAXLE/AUTOMATIC - NAG1/SHIFT

DISCONNECT MODULES
Note: The Controller Antilock Brake and Shift Lever Assembly
both use the SCI Transmit circuit at DLC cavity 9 to communicate
with the DRB III
T
. If one of these modules keeps the SCI Transmit
circuit artificially high or low, the DRB III
T
will not be able to com-
municate with any of the modules.
Note: Perform the following steps for each of the modules until
communication is restored with the other module or until each of
the modules has been eliminated as the cause of the fault.
Turn the ignition off.
Disconnect each of the modules noted above, one at a time.
Turn the ignition on.
Using the DRB III
T
, attempt to communicate with the other module still
connected.
Is the DRB III
T
able to communicate with the other module?
Yes >> Replace the module that was disconnected when communication was restored to the other module.
Perform BODY VERIFICATION TEST.
No >> Go to 8
