Chrysler Crossfire. Manual — part 159
*NO RESPONSE FROM POWERTRAIN CONTROL MODULE (CONTINUED)
9.
SCI TRANSMIT CIRCUIT SHORTED TO GROUND
With the ignition off.
Measure the resistance between ground and the PCM SCI Transmit
circuit.
Is the resistance above 100 kohms?
Yes
>> Go to 10
No
>> Repair the PCM SCI Transmit circuit for a short to ground.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
10.
SCI TRANSMIT CIRCUIT SHORTED TO VOLTAGE
Turn the ignition on.
Measure the voltage of the PCM SCI Transmit circuit at the DLC.
Is the voltage below 0.5 volt?
Yes
>> Replace the Powertrain Control Module. (Refer to 8 -
ELECTRICAL/ELECTRONIC CONTROL MODULES/POW-
ERTRAIN CONTROL MODULE - REMOVAL).
Perform POWERTRAIN VERIFICATION TEST - VER 2.
No
>> Repair the PCM SCI Transmit circuit for a short to voltage.
Perform POWERTRAIN VERIFICATION TEST - VER 2.

ULES - SCHEMATICS AND DIAGRAMS).
Diagnostic Test
1.
CHECK COMMUNICATION WITH OTHER MODULES
Turn the ignition on.
Using the DRB III
T
, attempt to communicate with any other module.
Is the DRB III
T
able to communicate with the module selected?
Yes
>> Go to 2
No
>> Perform Symptom *No Response From All Modules.
2.
FUSED IGNITION SWITCH OUTPUT CIRCUIT OPEN
WARNING: TURN THE IGNITION OFF, DISCONNECT THE BAT-
TERY AND WAIT TWO MINUTES BEFORE PROCEEDING.
Turn the ignition off.
Disconnect the Occupant Restraint Controller (ORC) harness connec-
tor.
Note: Check connector — Clean/repair as necessary.
Reconnect the battery.
Turn the ignition on.
Measure the voltage of the Fused Ignition Switch Output circuit at the
ORC harness connector.
Is the voltage above 10 volts?
Yes
>> Go to 3
No
>> Repair the Fused Ignition Switch Output circuit for an open.
WARNING: WHEN RECONNECTING AIRBAG SYSTEM COMPONENTS, THE IGNITION MUST BE TURNED OFF
AND THE BATTERY MUST BE DISCONNECTED FOR TWO MINUTES.
Perform AIRBAG VERIFICATION TEST.

3.
ORC GROUND CIRCUIT OPEN
Turn the ignition off.
Measure the resistance of the Ground circuit from the ORC harness
connector to ground.
Is the resistance below 5.0 ohms?
Yes
>> Go to 4
No
>> Repair the Ground circuit for an open.
WARNING: WHEN RECONNECTING AIRBAG SYSTEM COMPO-
NENTS, THE IGNITION MUST BE TURNED OFF AND THE BAT-
TERY MUST BE DISCONNECTED FOR TWO MINUTES.
Perform AIRBAG VERIFICATION TEST.
4.
SCI TRANSMIT CIRCUIT OPEN
With the ignition off.
Measure the resistance of the SCI Transmit circuit from the ORC har-
ness connector to the DLC.
Is the resistance below 5.0 ohms?
Yes
>>
Go to 5
No
>> Repair the SCI Transmit circuit for an open.
WARNING: WHEN RECONNECTING AIRBAG SYSTEM COMPO-
NENTS, THE IGNITION MUST BE TURNED OFF AND THE BAT-
TERY MUST BE DISCONNECTED FOR TWO MINUTES.
Perform AIRBAG VERIFICATION TEST.
5.
SCI TRANSMIT CIRCUIT SHORTED TO GROUND
With the ignition off.
Measure the resistance between ground and the SCI Transmit circuit.
Is the resistance above 100 kohms?
Yes
>> Go to 6
No
>> Repair the SCI Transmit circuit for a short to ground.
WARNING: WHEN RECONNECTING AIRBAG SYSTEM COMPO-
NENTS, THE IGNITION MUST BE TURNED OFF AND THE BAT-
TERY MUST BE DISCONNECTED FOR TWO MINUTES.
Perform AIRBAG VERIFICATION TEST.
