SUBJECT:
TIPM Flash - DTC's Indicating Short Circuits In The Wiring On The Trailer Or No Engine
Crank With DTC P1277 - Starter Control Circuit 2 Low
OVERVIEW:
This bulletin involves a discussion and reprogramming of the Totally Integrated Power
Module (TIPM).
MODELS:
2006 (DR/DH/D1) Ram Truck
NOTE: This bulletin applies to vehicles built prior to April 03, 2006 (MDH 0403XX).
SYMPTOM/CONDITION:
Customer may experience any of the following TIPM Diagnostic Trouble Codes (DTC's):
B166B - Left Trailer Tow Lamp Control Circuit Low. Trailer harness left lamp circuit
is shorted to ground.

is shorted to battery voltage.
B178C - Left Trailer Tow Lamp Control Circuit Over Current. Trailer harness left
lamp circuit is intermittently grounding.
B166F - Right Trailer Tow Lamp Control Circuit Low. Trailer harness right lamp
circuit is shorted to ground.
B1670 - Right Trailer Tow Lamp Control Circuit High. Trailer harness right lamp
circuit is shorted to battery voltage.

ground.
B2215 - Front Control Module Internal (TIPM). An internal fault code counter has
exceeded its limit of 250 counts and one or more electrical outputs controlled by the
TIPM have been disabled.
P1277 - Starter Control Circuit 2 Low (TIPM). The output feed current to the starter
solenoid has exceeded the upper current limit of 75 amps. This may result in a
no-crank condition.
DISCUSSION:
DTC's B1667, B166B, B166E, B166F, B178C and B2215:
1. These DTC's indicate that a (hard or intermittent) short circuit to GROUND exists in
the wiring of one or more of the TRAILER electrical harness circuits.
2. The TIPM retries the output on each ignition cycle or request (brake or turn signal
activation) in an attempt to enable the output in case the fault is intermittent.
3. DTC's B1667, B166B, B166E, B166F, and B178C may occur individually or in
combination with each other.
4. For the two over current DTC's, B166E and B178C, the fault is set when the TIPM has
detected electrical loads on the circuit greater than 15 amps.
5. If DTC B2215 is also present with one of more of the above DTC's, then this fault code
indicates that the TIPM has detected the faulted condition (short) on one or more of
the trailer circuits more than 250 times. When detected more than 250 times, the TIPM
disables the electrical output (turns off) to the respective faulty trailer circuit to protect
that circuit and the system.
6. Short circuits can be intermittent and will require diagnosis and repair of the trailer wire
harness.
7. Once the faulty circuit has been repaired, the dealer must use a scan tool to enable
the respective trailer circuit that was previously been turned off (disabled) due to DTC
B2215.
8. The new TIPM software raises the TIPM circuit trigger point from 15 amps. to 20
amps.
DTC's B166C and B1670:
1. These DTC's indicate that a short circuit to BATTERY voltage (12 volts) exists in the
wiring of one of the TRAILER electrical harness circuits.
DTC B2215 - Front Control Module (TIPM):
1. This fault code occurs when the TIPM detects a short (to ground or to battery) on one
of the trailer circuits more than 250 times.
2. When B2215 is present with one of the above trailer circuit faults the TIPM will turn off
(disable) the respective faulty trailer circuit or circuits.
3. This internal fault DOES NOT mean that the TIPM module is defective.
4. The TIPM memory can be cleared, this action will turn on a previously disabled trailer
circuit. If possible, the fault in the circuit should be repaired first before clearing the
TIPM memory.
5. DO NOT replace the TIPM without first attempting to clear the TIPM memory.
6. The dealer will need a scan tool to clear the TIPM memory.
7. If one or more of the TIPM outputs are disabled due to one of these conditions, normal
operation can be restored a maximum of five (5) times.
8. The TIPM will be rendered inoperative on the sixth attempt to clear the TIPM memory.
At this point the TIPM must be replaced. The DTC(s) that indicates the problem and
DTC 2215 will both remain ACTIVE. Neither fault code will can be cleared at this point.
08-021-06 REV. A -2-
DTC P1277 - Starter Control Circuit 2 Low (TIPM):
1. The TIPM monitors the output current to the starter solenoid for over-current
conditions.
2. The DTC is set when the output current to starter solenoid exceeds 75 amps.
3. On trucks equipped with a diesel engine, there may be times in cold climates when it is
normal for the starter solenoid current to exceed 75 amps.
4. If DTC B2215 is present in addition to DTC P1277, then a starter solenoid circuit
over-current condition has been detected by the TIPM module more than 250 times. At
this point, the circuit to the starter solenoid is turned off until the TIPM memory is
cleared.
5. The new TIPM software raises the TIPM current trigger point for DTC P1277 from 75
amps. to 100 amps.
DIAGNOSIS:
If any of the DTC's listed above are present, perform the Repair Procedure.
NOTE: The Repair Procedure (TIPM flash) currently can not be performed using the
StarMOBILE™ in its STANDALONE mode. Use the StarSCAN™ to perform
the Repair Procedure, or use the StarMOBILE™ in its CONNECTED mode to
perform the Repair Procedure.

NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
1. Open the hood and install a battery charger. Using a voltmeter, verify that the charging
rate provides 13.2 - 13.5 volts. Set the battery charger to continuous charge. Do not
allow the charger to time out during the flash process. Remove the charger from the
battery when the flash process is complete.
NOTE: Do not allow the charging voltage to climb above 13.5 volts during the flash
process.
2. Connect the CH9410 StarSCAN® ethernet cable to the StarSCAN® and the dealer's
network drop.
3. Connect the CH9404 StarSCAN® vehicle cable to the StarSCAN® and the vehicle.
4. Power ON the StarSCAN®.

TIPM Flash - Diagnostic Trouble Codes B178C, B166E, B2215 For Trailer Tow Lamps
Inoperative Indicating Short Circuits In The Wiring On The Trailer Or P1277 For No Crank -
Starter Solenoid Current Excessive.
OVERVIEW:
This bulletin involves Flash Reprogramming the Totally Integrated Power Module (TIPM).
MODELS:
2006 (DR/DH) Ram Truck
SYMPTOM/CONDITION:
Customer may experience any of the following TIPM Diagnostic Trouble Codes (DTC's)
with associated symptoms:
B178C - Left Stop Turn Over Current - Load on Left Stop/Turn circuit has exceeded
15 amps.
B166C - Right Stop turn Over Current - Load on Right Stop/Turn circuit has
exceeded 15 amps.
B2215 - Internal Fault - An Internal Fault code counter has exceeded its limit and an
output is disabled.
P1277 - Fault Code Counter Reaches Upper limit Start Solenoid Circuit Over
Current (Start Solenoid Current has exceeded the Upper Limit of 75 amps). Can be
accompanied by fault code B2215, indicating that the faulted condition has been
seen by the TIPM more than 250 times. If the B2215 fault code is present, the
Output circuit of the TIPM will not function, resulting in a no-crank condition.
DISCUSSION:
- DTC'c B178C, B166C and P2215 indicate that short circuits exist in the wiring on
the trailer. The fault is set when the TIPM has seen loads on the circuit greater than
15 amps. TIPM retries the output on each ignition cycle or request (brake or turn
signal activation) to attempt to enable the output in case of an intermittent faulted

condition. The short circuits are usually intermittent and will require diagnosis and
repair. If Present, the B2215 fault code indicates that the TIPM has seen the faulted
condition >250 times and has turned off the output to protect the system. TIPM
trigger points for the trailer tow outputs has been increased from 15 amps to 17.5
amps, and the fault reporting strategy has been changed to be less susceptible to
trailer wiring problems. With this service flash, the TIPM will no longer permanently
deactivate the trailer tow outputs and the B2215 DTC will no longer be set.
- Each of these DTC's, including B2215 - Internal Fault, can be cleared from the
TIPM module memory but this can only be done a maximum of 5 times. The TIPM
module will be rendered inoperative on the sixth attempt and must be replaced.
- DCT B2215 - Internal Fault does not mean that the TIPM module is defective.
- DCT P1277 - Start Solenoid Circuit Over Current - The TIPM Module Monitors
starter Solenoid Current and contains a set point of 75 amps to trigger the DTC.
When this DTC is set, the TIPM renders the starter solenoid inoperative for that
ignition cycle, to protect the wiring. If the B2215 fault code (FCM Internal Fault) is
shown in addition to the P1277 code, this means that the Over Current Condition
has been seen by the TIPM module more than 250 times. On Diesel engine
equipped trucks there can be normal situations where the starter solenoid current
can exceed 75 amps. This software will change the DTC trigger to 100 amps.
DIAGNOSIS:
If any of the DTC's listed above are present, perform the Repair Procedure.
