Dodge Ram Truck 1500-2500-3500. Manual — part 375

PRNDL SWITCH INPUT CIRCUIT SHORTED (DIESEL ONLY) (CONTINUED)

For the Instrument Cluster circuit diagram (Refer to 8 - ELECTRICAL/INSTRUMENT CLUSTER - SCHEMATICS
AND DIAGRAMS).

For a complete wiring diagram Refer to Section 8W.

•

When Monitored:
With the ignition on.

•

Set Condition:
The instrument Cluster detects that a short condition exists in the PRNDL circuit.

Possible Causes

(T117) TRANSMISSION RANGE SENSOR ELECTRONIC CLUSTER 5 VOLT SUPPLY CIRCUIT SHORT TO THE
(T917) TRANSMISSION RANGE SENSOR ELECTRONIC CLUSTER MUX CIRCUIT

(T117) TRANSMISSION RANGE SENSOR ELECTRONIC CLUSTER 5 VOLT SUPPLY CIRCUIT SHORT TO
GROUND

TRANSMISSION RANGE SENSOR

NOTE: Ensure that the correct Instrument Cluster is installed and is correctly configured for the vehicle.
Turn the ignition off.

Disconnect the Transmission Range Sensor harness connector.

Turn the ignition on.

With the DRBIII

T

, read DTCs.

Does the DRBIII

T

display PRNDL Input Circuit Open?

Yes

>> Replace the Transmission Range Sensor in accordance with the Service Information.

(T117) TRANSMISSION RANGE SENSOR ELECTRONIC CLUSTER 5 VOLT SUPPLY CIRCUIT SHORT TO
THE (T917) TRANSMISSION RANGE SENSOR ELECTRONIC CLUSTER MUX CIRCUIT

Turn the ignition off.

Disconnect the Transmission Range Sensor harness connector.

Disconnect the Instrument Cluster C3 and C4 harness connectors.

Measure the resistance between the (T117) Transmission Range Sen-
sor Electronic Cluster 5 Volt Supply circuit and the (T917) Transmis-
sion Range Sensor Electronic Cluster MUX circuit.

Is the resistance below 5.0 ohms?

Yes

>> Repair the (T117) Transmission Range Sensor Electronic

Cluster 5 Volt Supply circuit for a short to the (T917)
Transmission Range Sensor Electronic Cluster MUX cir-
cuit.

Perform BODY VERIFICATION TEST - VER 1. (Refer to
BODY VERIFICATION TEST - VER 1.)

No

>> Go To 3

3.

(T117) TRANSMISSION RANGE SENSOR ELECTRONIC CLUSTER 5 VOLT SUPPLY CIRCUIT SHORT TO
GROUND

Measure the resistance between ground and the (T117) Transmission
Range Sensor Electronic Cluster 5 Volt Supply circuit.

Is the resistance below 5.0 ohms?

Yes

>> Repair the (T117) Transmission Range Sensor Electronic

Cluster 5 Volt Supply circuit for a short to ground.

Perform BODY VERIFICATION TEST - VER 1. (Refer to
BODY VERIFICATION TEST - VER 1.)

No

>> Replace and configure the Instrument Cluster in accor-

dance with the Service Information.

VIN CHECKSUM ERROR

For a complete wiring diagram Refer to Section 8W.

•

When Monitored:
With the ignition on.

•

Set Condition:
Once the Instrument Cluster learns a valid VIN and another valid VIN is transmitted on the bus. The Instru-
ment Cluster decodes the VIN that is transmitted on the bus by the PCM. If the VIN is valid the Instrument
Cluster stores the information. If the VIN information does not equate to the encrypted value then the fault is
set.

Possible Causes

another.
If any components have been exchanged or
