Reverse lamp fuse - 1995 Dodge Neon

Backup Lamps
The fuse block - rear supplies battery positive voltage to the reverse lamp relay control and to the switch terminals of the REVERSE relay. Battery positive voltage to the switch terminal is available through the PARK/REV fuse. The dash integration module (DIM) sends a power mode message to the rear integration module (RIM) indicating that the ignition is in the ON position. When the driver selects the REVERSE position, the powertrain control module (PCM) sends a class 2 message to the RIM. The message indicates that the gear selector lever is in the REVERSE position. The RIM then energizes the REVERSE relay and the backup lights illuminate. Current flows from the REVERSE relay switch to the backup lamps. The backup lamps have ground at G401 and at G402.

Your best bet , take it to a qualified repair shop.

Install a scan tool.
Turn ON the ignition, with the engine OFF.
With the scan tool, command the reverse lamp relay ON and OFF from the rear integration module (RIM) Output Control data list.
Does the reverse lamp relay turn ON and OFF with each command?

Turn OFF the ignition.
Disconnect the reverse relay. Refer to Relay Replacement in Wiring Systems.
Turn ON the ignition, with the engine OFF.
Probe the reverse relay control side supply voltage circuit with a test lamp that is connected to a good ground.
Does the test lamp illuminate?

Battery voltage from the CHMSL/BCK-UP fuse located in the rear fuse block is supplied to the body control module (BCM) for backup lamp operation. When the gear selector is placed in to the REVERSE position, the powertrain control module (PCM) sends a GMLAN serial data message to the BCM indicating that the gear selector is in the reverse position. The BCM then applies battery voltage to the backup lamp supply voltage circuit illuminating the left and right backup lamps. Ground for both backup lamps is provided at G403.

You might need to make sure that the reverse switch is sending a 12v signal to the backup lamps.

Backup Lamps
The backup lamp request signal is sent from the powertrain control module (PCM) to the body control module (BCM) on the class 2 message system. This signal is based on the park neutral position (PNP) switch signal. The BCM supplies voltage on the backup lamp supply voltage circuit to the backup lamps and to the automatic day/night mirror. Voltage for the courtesy lamp supply voltage circuit and backup lamp supply voltage circuit is from the TBC B fuse in the instrument panel fuse block directly through the BCM to these circuits. A short to ground on either of these circuits will open the fuse. The backup lamps are grounded at G401.
For trailer wiring, a separate backup lamp circuit is connected through the underhood fuse block from the TRLR B/U 10 A fuse to the trailer wiring harness.

Did you check the fuse , relay ? Backup Lamps
The B/U LAMP fuse in the RH I/P fuse block supplies battery positive voltage to the switch terminal of the backup lamps relay. The DIC/RKE fuse supplies battery positive voltage to the backup lamps relay coil terminal. When you place the gear selector lever in the REVERSE position, the powertrain control module (PCM) sends a class 2 message to the body control module (BCM). When these conditions occur, the BCM energizes the reverse lamp relay control circuit, closing the switch contacts, the current flows from the reverse lamp relay switch to the backup lamps. The backup lamps are grounded at G302.

Backup Lamps
The TURN SIG fuse in the console fuse block supplies battery positive voltage to park neutral position switch. When the gear selector lever is in the REVERSE position, power is supplied to both of the backup lamps. The backup lamps are grounded at G401 and G402.
Do you know what DTC'S - diagnostic trouble codes are ?
DTC B2552
The body control module (BCM) controls the backup lamp relay. The BCM grounds the backup lamp relay control circuit energizing the backup lamp relay. The BCM connects directly to the center console fuse block with no external wiring between them.
DTC B2553
The body control module (BCM) controls the backup lamp relay. The BCM grounds the backup lamps relay control circuit energizing the backup lamp relay. The BCM connects directly to the center console fuse block with no external wiring between them.

Reversing Lamps

The reversing lamp system consists of the following components:

• Rear lamps
• Reversing lamp switch
• PCM
• BCM

When the transmission is placed in REVERSE (R), the BCM provides voltage to the reversing lamps. The reversing lamps are located within the rear lamp assemblies.
When the transmission is in REVERSE, the PCM (gasoline engine) or the Transmission Control Module (TCM) (diesel engine) sends a message over the High Speed Controller Area Network (HS-CAN) to the Body Control Module (BCM) indicating the transmission is in REVERSE. The BCM provides voltage to the reversing lamps when it receives the message that the transmission is in REVERSE and the ignition is in the RUN state. You could have a transmission range sensor problem , check to see if it is adjusted correctly ! Need to have a scan tool to make sure the BCM is receiving signal from the PCM . This is complex for someone who doesn't deal with or know about serial data communications ! All it is ,is electric inputs to a control module, then the control module configures it into data bits an bytes 1's an 0's then sends it out on the Data bus. The module that needs this info reads it an turns on the lights.This system can set codes in the bcm ,leading to a problem.

DTC B1277:11 (Reverse Lamp: Circuit Short To Ground) - a DTC that sets when the BCMdetects a short to ground from the reversing lamp output circuit.

DTC B1277:15 (Reverse Lamp: Circuit Short To Battery or Open) - a DTC that sets when the BCMdetects an open from the reversing lamp output circuit.

Could set codes in the PCM - powertrain control module for a transmission range sensor problem !

Not sure which part you mean no power.

For the New Body style 2004 ( not a Heritage or Lightning model )

If both Stop / Turn pins & the parking lamps, might want to check the ground pin to make sure it is good ( or what you are using for ground on the test light / meter ).

The trailer tow parking lamp circuit is fuse #10 to the parking lamp relay

The stop / turn circuits also have fuses on each one, Fuse #36 & Fuse # 42 ( R & L ).

The 7 pin has fuses for the battery charge pin ( hot in run position ) and the reverse circuit ( hot in run & when in reverse ), Reverse is also fuse # 10 to the trailer tow reversing lamp relay & the battery charge pin is fuse # 106 to the trailer tow battery charge relay.

Could be all the fuses are blown, or what you are using for ground on the meter / test light is not a good ground.

Trailer Tow reversing relay ( non serviceable ) and the Trailer tow parking lamp relay are both fed from Fuse #10 ( coil on reversing relay is fed from reverse lamps & coil on parking lamp relay is fed from the parking lamps ).

Trailer Tow battery charge relay is fed from Fuse #106 ( coil is fed by fuse #13, hot in start / run position from key ).

Right Stop / Turn is fed from Fuse #36 ( powered from MFS circuit for truck stop/turn )
Left Stop / Turn is fed from Fuse #42 ( powered from MFS circuit for truck stop/turn )

Parking lamp is

Unfortunately, many possibilities. If you have time, start by removing both reverse lamp sockets from light assembly(and keep from touching any metal), remove bulbs from sockets, CAREFULLY INSPECT sockets and wires. New fuse of correct rating. Turn key on and try again in reverse.
Fuse still blows: Next place to look is transmission reverse electrical switch and wiring as far as you can trace looking for burned/stripped wires near transmission and wires by sockets
Fuse doesn't blow: Turn key off and install one lamp in socket at a time. DO NOT install sockets into fixture at this time. Test. Remove first lamp to check second. If still O.K., each socket back into fixture(one at a time same as before)and test. Most common problems: Sockets contaminated, wires shorting at sockets, bulbs installed incorrectly shorting to ground.
