Chrysler 300/300 Touring/300C, Dodge Magnum. Manual — part 222
•
When Monitored:
With the ignition on.
•
Set Condition:
If the Dynamics Sensor status changes from initialized to not initialized due to low voltage on the (G4) Dynam-
ics Sensor Supply circuit.
Possible Causes
WIRING HARNESS, TERMINAL, CONNECTOR DAMAGE
(G4) DYNAMICS SENSOR SUPPLY CIRCUIT HIGH RESISTANCE
(G94) DYNAMICS SENSOR GROUND CIRCUIT HIGH RESISTANCE
(G4) DYNAMICS SENSOR SUPPLY CIRCUIT SHORTED TO OTHER ABS CIRCUITS

1.
VERIFY DTC IS ACTIVE
Turn the ignition on.
With the scan tool, read and record ABS DTCs.
With the scan tool, read and record Environmental Data (EV Data).
With the scan tool, erase ABS DTCs.
Cycle the ignition switch.
With the scan tool, read ABS DTCs.
Does this DTC reset?
Yes
>> Go To 2
No
>> Perform the ABS Intermittent Condition diagnostic procedure in this Section.
Perform ABS VERIFICATION TEST - VER 1. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
2.
INSPECT RELATED WIRING HARNESS, TERMINALS, & CONNECTORS
Turn the ignition off.
Check all related wiring for pinched, chafed, pierced, and partially broken wires.
Check all related connectors for broken, bent, pushed out, and corroded terminals.
Were any problems found?
Yes
>> Repair as necessary.
Perform ABS VERIFICATION TEST - VER 1. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No

3.
CHECK (G4) DYNAMICS SENSOR SUPPLY CIRCUIT & (G94) DYNAMICS SENSOR GROUND CIRCUIT
FUNCTION
Disconnect the Dynamics Sensor harness connector.
Turn the ignition on.
Measure the voltage between the (G4) Dynamics Sensor Supply Circuit
and the (G94) Dynamics Sensor Ground Circuit.
Is the voltage above 4.5 volts?
Yes
>> Replace the Dynamics Sensor in accordance with the Ser-
vice Information.
Perform ABS VERIFICATION TEST - VER 1. (Refer to 5 -
BRAKES - STANDARD PROCEDURE).
No
>> Go To 4
4.
CHECK (G4) DYNAMICS SENSOR SUPPLY CIRCUIT FOR HIGH RESISTANCE
Turn the ignition off.
Disconnect the Anti-Lock Brakes Module harness connector.
Measure the resistance of the (G4) Dynamics Sensor Supply circuit
between the Dynamics Sensor harness connector and the Anti-Lock
Brakes Module harness connector.
Is the resistance below 5.0 ohms?
Yes
>> Go To 5
No
>> Repair the (G4) Dynamics Sensor Supply circuit for high
resistance.
Perform ABS VERIFICATION TEST - VER 1. (Refer to 5 -
BRAKES - STANDARD PROCEDURE).
5.
CHECK (G94) DYNAMICS SENSOR GROUND CIRCUIT FOR HIGH RESISTANCE
Measure the resistance of the (G94) Dynamics Sensor Ground circuit
between the Dynamics Sensor harness connector and the Anti-Lock
Brakes Module harness connector.
Is the resistance below 5.0 ohms?
Yes
>> Go To 6
No
>> Repair the (G94) Dynamics Sensor Ground circuit for high
resistance.
Perform ABS VERIFICATION TEST - VER 1. (Refer to 5 -
BRAKES - STANDARD PROCEDURE).

6.
CHECK (G4) DYNAMICS SENSOR SUPPLY CIRCUIT FOR A SHORT TO OTHER ABS CIRCUITS
Measure the resistance between the (G4) Dynamics Sensor Supply cir-
cuit and the B46, B15, D21, D65, D64, Z127, D52, D51, G94, B6, B7,
B4. B3, B1, B2, B9, B8, and Z107 circuit in the Anti-Lock Brakes Mod-
ule harness connector.
Is the resistance below 10k ohms on any of the circuits?
Yes
>> Repair all circuits with a resistance below 10k ohms for a
short to the (G4) Dynamics Sensor Supply circuit.
Perform ABS VERIFICATION TEST - VER 1. (Refer to 5 -
BRAKES - STANDARD PROCEDURE).
No
>> Replace the Anti-Lock Brakes Module in accordance with
the Service Information.
Perform ABS VERIFICATION TEST - VER 1. (Refer to 5 -
BRAKES - STANDARD PROCEDURE).
