Chrysler Crossfire. Manual — part 78
ESP YAW RATE SENSOR CIRCUIT (CONTINUED)
11.
MEASURE THE RESISTANCE OF THE ESP YAW RATE SENSOR 5-VOLT SUPPLY CIRCUIT
With the ignition off.
Measure the resistance of the 5-Volt Supply circuit from the ESP Yaw
Rate Sensor harness connector to the CAB harness connector.
Is the resistance below 5.0 ohms?
Yes
>> Replace the Controller Antilock Brake. (Refer to 8 - ELEC-
TRICAL/ELECTRONIC CONTROL MODULES/CONTROL-
LER ANTILOCK BRAKE - REMOVAL).
Perform ABS VERIFICATION TEST.
No
>> Repair the ESP Yaw Rate Sensor 5-Volt Supply circuit for
an open.
Perform ABS VERIFICATION TEST.

STEERING ANGLE SENSOR CIRCUIT (CONTINUED)
When Monitored and Set Condition
•
When Monitored: With the ignition on. The Controller Antilock Brake (CAB) monitors the status of the Steering
Angle Sensor.
•
Set Condition: The DTC will set if a malfunction is detected between the CAB and the Steering Angle Sensor.
POSSIBLE CAUSES
DISCONNECTED BATTERY
FUSED B(+) CIRCUIT OPEN
FUSED IGNITION SWITCH OUTPUT CIRCUIT OPEN
STEERING ANGLE SENSOR GROUND CIRCUIT OPEN
STEERING ANGLE SENSOR SIGNAL CIRCUIT OPEN
STEERING ANGLE SENSOR SIGNAL CIRCUIT SHORT TO GROUND
STEERING ANGLE SENSOR SIGNAL CIRCUIT SHORT TO VOLTAGE
STEERING ANGLE SENSOR
CONTROLLER ANTILOCK BRAKE
For a complete Electronic Stability Program (ESP) Circuit Diagram (Refer to 5 - BRAKES/ELECTRICAL - SCHE-
MATICS AND DIAGRAMS).
Note: This DTC will set if the battery has been disconnected. Before performing any diagnostics confirm
that the steering angle sensor is calibrated correctly. If the DTC is current, and the battery has been previ-
ously disconnected, perform the following procedure to recalibrate the steering angle sensor.
•
Turn the ignition switch on.
•
Rotate the steering wheel to the center position.
•
Rotate the steering wheel to the full left stop.
•
Rotate the steering wheel to the full right stop.
•
Rotate the steering wheel back to the center position.
•
Sensor recalibration is now complete, and the ESP/BAS light should be off. If the light is still on, continue
to Step 1 of the Diagnostic Test for this DTC.

STEERING ANGLE SENSOR CIRCUIT (CONTINUED)
Diagnostic Test
1.
CHECK STEERING ANGLE SENSOR SIGNAL VOLTAGE
Note: Inspect Fuse 14 located in the Underhood Accessory Fuse
Block. If the fuse is open, repair the cause of the open fuse
before continuing.
Turn the ignition off.
Disconnect the Controller Antilock Brake harness connector.
Note: Check connectors - Clean/repair as necessary.
Turn the ignition on.
Measure the voltage of the Steering Angle Sensor Signal circuit at the
Controller Antilock Brake harness connector while slowly rotating the
steering wheel from the full right position to the full left position.
Note: It may be helpful to raise the front wheels off the ground
and support the vehicle using appropriate safety measures.
Does the voltage vary between 7.0 and 9.5 volts?
Yes
>> Replace the Controller Antilock Brake. (Refer to 8 - ELEC-
TRICAL/ELECTRONIC CONTROL MODULES/CONTROL-
LER ANTILOCK BRAKE - REMOVAL).
Perform ABS VERIFICATION TEST.
No
>> Go to 2
2.
MEASURE STEERING ANGLE SENSOR FUSED B(+) CIRCUIT VOLTAGE
Turn the ignition off.
Disconnect the Steering Angle Sensor harness connector.
Note: Check connectors - Clean/repair as necessary.
Turn the ignition on.
Measure the voltage of the Fused B(+) circuit at the Steering Angle
Sensor harness connector.
Is the voltage above 10 volts?
Yes
>> Go to 3
No
>> Repair the Steering Angle Sensor Fused B(+) circuit.
Perform ABS VERIFICATION TEST.
