DTC SET CONDITIONS <SHIFT FORK 2
CURRENT GEAR: 3RD GEAR>

Check Conditions

• Voltage of battery: 8 V or more.

• Voltage of battery: 16.5 V or less.

• Engine speed: 500 r/min or more.

• Time since above engine condition: 400 millisec-

JUDGMENT CRITERIA

• Shift fork 2 position: −6 mm (−0.24 inch) or more.

(250 millisecond)

OBD-II DRIVE CYCLE PATTERN <SHIFT
FORK 2 CURRENT GEAR: 3RD GEAR>

The travel distance of the shift fork 2 remains

−6 mm

(

−0.24 inch) or less for 250 milliseconds.

PROBABLE CAUSES

• Malfunction of TC-SST-ECU

DIAGNOSTIC PROCEDURE

STEP 1. Scan tool CAN bus diagnostics
Using scan tool MB991958, diagnose the CAN bus lines.
Q: Is the check result normal?

YES : Go to Step 2.
NO : Repair the CAN bus lines. (Refer to GROUP 54C

STEP 2. Check whether the DTC is reset.
Q: Is DTC No. P1829 set?

YES : Replace the TC-SST assembly. (Refer to

P.22C-341

NO : Intermittent malfunction. (Refer to GROUP 00

P.00-15

DTC P182A: Shift Fork Position Sensor 3 System (Voltage low range out)

CAUTION

• If there is any problem in the CAN bus lines,

an incorrect diagnostic trouble code may be
set. Prior to this diagnosis, diagnose the CAN
bus lines.

• Whenever the ECU is replaced, ensure that

the CAN bus lines are normal.

DIAGNOSTIC FUNCTION

TC-SST-ECU checks that the voltage of the shift fork
position sensor 3 is normal.

DESCRIPTIONS OF MONITOR METHODS

The voltage of the shift fork position sensor 3 is too
low.

MONITOR EXECUTION
