Actually just have P1585 code

Hi,

the code indicates an issue with the transmission (cvt) and the acceleration sensor circuit. i realize you did scan the computer, but in this case, you should scan the entire can bus system. can stands for computer area network. i have a feeling that is where the problem will be found. here is a video showing how this is done:

now, i do have the diagnostics for the code. i will include them here.

dtc p1585 acceleration sensor circuit

description
the ecm determines the vehicle inclination based on a signal from the airbag sensor assembly (yaw rate and acceleration sensor). if a malfunction in the airbag sensor assembly (yaw rate and acceleration sensor) is determined based on a malfunction signal from the brake actuator assembly (skid control ecu), the ecm cancels neutral control as a fail-safe function.

hint: the airbag sensor assembly (yaw rate and acceleration sensor) signal is sent to the brake actuator assembly (skid control ecu) via can communication.
if can communication dtcs are output, perform troubleshooting for those dtcs first.

see pic 1 and 2. i overlapped them so you could follow the procedure.

caution / notice / hint
notice:

perform the universal trip to clear permanent dtcs.

procedure
1. check dtc output
connect the techstream to the dlc3.
turn the ignition switch to on.
turn the techstream on.
check for dtcs.
powertrain / engine and ect / trouble codes
result:

b -- go to can communication system networking: can communication system(w/o central gateway ecu / diagnosis system / networking: can communication system(w/o central gateway ecu) diagnosis system networking: can communication system (w/o central gateway ecu) diagnosis system

2. read value using techstream (g sensor)
connect the techstream to the dlc3.
turn the ignition switch to on.
turn the techstream on.
enter the following menus: powertrain / engine and ect / data list / primary.
in accordance with the display on the techstream, read the data list.

3. replace airbag sensor assembly
replace the airbag sensor assembly (yaw rate and acceleration sensor).

result: proceed to next

4. perform initialization
notice:

performing reset memory will clear the learned value of the yaw rate and acceleration sensor (deceleration sensor zero point calibration) and the cvt oil pressure (cvt oil pressure calibration). make sure to perform reset memory, yaw rate and acceleration sensor zero point calibration, and cvt oil pressure calibration when replacing any of the parts shown in the following table:

after performing reset memory, always perform yaw rate and acceleration sensor (deceleration sensor zero point) calibration first, and then cvt oil pressure calibration.
always perform calibration with the vehicle on level ground.
do not shake or vibrate the vehicle during calibration.
using the techstream, perform reset memory, deceleration sensor zero point calibration and cvt oil pressure calibration.

check out the diagrams (below). let us know what happens and please upload pictures or videos of the problem.

Hi,

I attached the schematics for the computer data line schematics for you. Let me know if that is what you needed.

Hi,

No problem. I enlarged the schematics and then cut them in half to make them more readable. I did overlap them so you could follow from one to the next.

Let me know if this helps.
