it scans c0196 code yaw rate / tried resetting, it wont any ideas bad sensor? thanks

no warranty

any help would be appreciated , i was reading you could un plug it step on the breaks ect to reset/ calibrate it

Posted (edited)

its either 3 things ,EBCM or Yaw sensor or wiring

 

there is a bulletin for dash lights on and no codes,,,

 

this is from the code ,,,,,i hope ya feel lucky

 

i recommend taking it in but guys dont like me saying that .....good luck !!!!

 

 


Circuit/System Testing






1.
Verify that DTC U2142 is not
set.







If the DTC is set, refer to DTC
U2105-U2199
.






2.
Verify that DTC C0710 is not
set.







If the DTC is set, refer to DTC C0710
.






3.
Ignition OFF, disconnect the harness connector
at the yaw/lateral accelerometer sensor.






4.
Ignition OFF and all vehicle systems OFF. It
may take up to 2 minutes for all vehicle systems to power down. Test for less
than 10 Ω between the ground circuit terminal 1 and
ground.







If greater than the specified range, test the ground circuit for
an open/high resistance.






5.
Disconnect the harness connector at the
EBCM.






6.
Test for infinite resistance between the 12 V
reference circuit terminal 32 of the EBCM connector and
ground.







If not the specified value, test the 12 V reference circuit for a
short to ground.






7.
Test for less than 2 Ω between the 12 V
reference circuit terminal 32 of the EBCM connector and terminal 4 of the
yaw/lateral accelerometer sensor
connector.







If greater than the specified range, test the 12 V reference
circuit for open/high resistance.






8.
If all circuits test normal, replace the
yaw/lateral accelerometer sensor. If the DTC resets, replace the EBCM.

thanks will check tomorrow .....im never lucky..

do you have to flash/ program sensor or ecbm to vehicle if replaceing

EBCM needs to be programed only

 

 

price out the yaw sensor and then decide on risk

 

as said ,im not recommending replacing anything ,,its on you ,risk, vs reward crap

just to follow up, did all the test you advised , wiring checked out , ordered yaw sensor ,installed it and it cleared the code ..thanks for your help

Its a 11 and you don't have a warrenty left?

    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?   
    • Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
