My reverse is out what could be the problem? - 1999 Ford Explorer

NOT TRUE AT ALL
IF REVERSE LAMPS DO NOT GLOW.!
ARE THE REVERSE LAMPS DEAD, KEY ON = PRNDL REVERSE SELECTED?
IF METER NEG LEAD IS ON GROUND
AND METER PLUS LEAD (VOLTS) IS TOUCHING REVERSE LAMP PIN , KEY OFF NO HOT.
KEY ON, IN REVERSE YES HOT (12VDC =HOT)
AND THE 2 LAMPS MUST GLOW OR THE METER IS NOT CONNECTED CORRECTLY

START BY TESTING THAT REVERSE LAMPS DO INFACT WORK
AND NOT KEY OFF
AND NOT GLOW IN DRIVE AND PARK AND NEUTRAL.

In the BJB - battery junction box under the hood ,is a reversing lamp relay. Check it or try a known good one !an check fuse F70 10amp in the BJB .

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 !

You say that the reverse lights go out when reverse gear is selected! At what point are they on? Before reverse is selected?

look on the tranny for the reverse light switch near the pan

Reverse clutch pack problem .

the reverse clutch in the trans is after failing.there are two clutch packs in trans for reverse,low/reverse and reverse clutch in overdrive unit,so where you have all foward gears the low/ reverse is ok the reverse clutch in od unit is most likely culpret

On the side of your transmission will be a switch with several wires coming out of it. This is your reverse switch that turns on your reverse lights and most likely needs to be replaced

reverse clutch went out rebuild transmission
