no headlights

Most of the time my headlights are not working on my 2010 Liberty. The problem started about a week ago. No other issues with anything electrical. They malfunction in both manual and automatic. Running lights are fine.

The following DTC codes have been scanned:

B162 F
B162 B
B 1637
B 1633
This covers both left and right and high and low, control circuit low.

Is there a separate front control module from the TIPM ?

Check for an intermittent (you said most, but not all of the time) condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals.

Info from the FSM:

B162F-RIGHT LOW BEAM CONTROL CIRCUIT LOW
When Monitored:
With the Headlamps activated.
Set Condition:
When the Totally Integrated Power Module (TIPM) detects a shorted low condition when the right low beam is on.
Possible Causes
(L44) RIGHT LOW BEAM CONTROL CIRCUIT SHORTED TO GROUND
RIGHT LOW BEAM BULB
TOTALLY INTEGRATED POWER MODULE (TIPM)

B162B-LEFT LOW BEAM CONTROL CIRCUIT LOW
When Monitored:
With the Headlamps activated.
Set Condition:
When the Totally Integrated Power Module (TIPM) detects a low condition.
Possible Causes
(L43) LEFT LOW BEAM CONTROL CIRCUIT SHORTED TO GROUND
LEFT LOW BEAM BULB
TOTALLY INTEGRATED POWER MODULE (TIPM)

B1637-RIGHT HIGH BEAM CONTROL CIRCUIT LOW
When Monitored:
With the High Beam Headlamps activated.
Set Condition:
When the Totally Integrated Power Module (TIPM) detects a low condition.
Possible Causes
(L34) RIGHT HIGH BEAM CONTROL CIRCUIT SHORTED TO GROUND
RIGHT HIGH BEAM BULB
TOTALLY INTEGRATED POWER MODULE (TIPM)

B1633-LEFT HI BEAM CONTROL CIRCUIT LOW
When Monitored:
With the Headlamps activated.
Set Condition:
When the Totally Integrated Power Module (TIPM) detects a low condition.
Possible Causes
(L33) LEFT HIGH BEAM CONTROL CIRCUIT SHORTED TO GROUND
LEFT HIGH BEAM BULB
TOTALLY INTEGRATED POWER MODULE (TIPM)

The wiring all looks good as far as I can tell. Any idea where I could find the information on which terminals go to the headlights from the TIPM? A wiring diagram would be great.

I believe that I have resolved my issue without having to purchase a new TIPM. I would be happy to share the details with anyone that may be interested.

Having same issue here. Codes pulled are the same as well. Please advise or PM on details of what you have found. Would like to find out if it would work for mine as well. Thanks.
