RAM 1500 Truck 2WD V8-5.7L VIN 2 (2006)
amps.
5.
If DTC B2215 is also present with one of more of the above DTC's, then this fault code indicates that the 11PM 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 11PM 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 11PM 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.
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(TM) in its STANDALONE mode. Use the
StarSCAN(TM) to perform the Repair Procedure, or use the StarMOBILE(TM) in its CONNECTED mode to perform the Repair Procedure.
