DTC P1586: Acceleration Sensor Malfunction [08/2013 - 08/2016]: Procedure

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

Result	Proceed to
DTC U0129 is not output	A
DTC U0129 is output	B

Result: 2

GO TO CAN COMMUNICATION SYSTEM: DIAGNOSIS SYSTEM [08/2013 - 04/2014] , DIAGNOSIS SYSTEM [04/2014 - 08/2015] , DIAGNOSIS SYSTEM [08/2015 - 08/2016]

Result: 1

See step 2

CHECK DTC OUTPUT (IN ADDITION TO DTC P1586)

Connect the Techstream to the DLC3.
Turn the Techstream on.
Turn the ignition switch to ON.
Clear the DTCs.
Powertrain > Engine and ECT > Clear DTCs
Perform a road test where the vehicle is driven at 30 km/h (18 mph) or more, the brakes are applied at least 16 times and the vehicle is finally stopped.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
Powertrain > Engine and ECT > Trouble Codes

Read the DTCs using the Techstream.

HINT:

If any DTCs other than P1586 are output, perform troubleshooting for those DTCs first.

Result

Result	Proceed to
Only DTC P1586 is output	A
DTC P1586 and other DTCs are output	B

Result: 2

GO TO DTC CHART: DIAGNOSTIC TROUBLE CODE CHART [08/2013 - 08/2014] , DIAGNOSTIC TROUBLE CODE CHART [08/2014 - 08/2016]

Result: 1

See step 3

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.

Powertrain > Engine and ECT > Data List

Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
G Sensor	Converted output voltage of G sensor	min.: 0 V max.: 79.998 V	Displays converted voltage of G sensor 2.31 V to 2.69 V: Vehicle on level ground 1.88 V to 2.5 V: Decelerating 2.5 V to 3.11 V: Accelerating Set to 1.87 V: G sensor malfunction Set to 1.87 V: Communication malfunction	-

REPLACE BRAKE ACTUATOR ASSEMBLY. Refer to COMPONENTS [08/2013 - 04/2014] Refer to COMPONENTS [04/2014 - 08/2015] Refer to COMPONENTS [08/2015 - 08/2017]

Result: 1

See step 4

REPLACE AIRBAG SENSOR ASSEMBLY

Replace the airbag sensor assembly (yaw rate and acceleration sensor).

Refer to COMPONENTS [08/2013 - ]

Result: 1

See step 5

PERFORM INITIALIZATION

NOTE:

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:

Replaced Part
Continuously variable transaxle assembly ECM Oil pressure sensor Airbag sensor assembly (Yaw rate and acceleration sensor)

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.
Refer to INITIALIZATION [08/2013 - 08/2016]

Check for DTCs again.

Refer to DTC CHECK / CLEAR [08/2013 - ]
