P074C UNABLE TO ENGAGE 4GR

P074C UNABLE TO ENGAGE 4GR

Description

INFOID:0000000009267961

This malfunction is detected when the A/T does not shift into 4GR position as instructed by TCM. This is not

only caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such as control

valve sticking, improper solenoid valve operation, etc.

DTC CONFIRMATION PROCEDURE

CAUTION:

• “

TM-191, "Diagnosis Procedure"

” must be performed before starting “DTC CONFIRMATION PROCE-

DURE”.

• Never perform “DTC CONFIRMATION PROCEDURE” before completing the repair, which may cause

secondary malfunction.

• Always drive vehicle at a safe speed.

1.

PREPARATION BEFORE WORK

If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at

least 10 seconds, then perform the next test.

>> GO TO 2.

2.

CHECK DTC DETECTION

With CONSULT

1. Select “4TH GR FNCTN P0734” in “DTC & SRT confirmation” in “TRANSMISSION”.

NOTE:

"4TH GR FNCTN P0731" can be used in this diagnosis.

2. Drive vehicle according to the following conditions.

3. Keep the current driving status for 2 seconds or more if CONSULT screen changes from “OUT OFCONDI-

TION” to “TESTING”.

CAUTION:

When “TESTING” is not indicated on CONSULT for a long time, check “Self Diagnostic Results” in

“TRANSMISSION”. When a DTC other than “P074C” is detected, check the DTC. Refer to 

TM-109,

"DTC Index"

.

P0863 TCM COMMUNICATION

P0863 TCM COMMUNICATION

Description

INFOID:0000000009267964

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-

tiplex communication line with high data communication speed and excellent malfunction detection ability.

Many electronic control units are equipped onto a vehicle, and each control unit shares information and links

with other control units during operation (not independent). In CAN communication, control units are con-

nected with 2 communication lines (CAN-H and CAN-L) allowing a high rate of information transmission with

less wiring. Each control unit transmits/receives data but selectively reads required data only.
