AUTOMATIC TRANSAXLE DIAGNOSIS <A/T>

TSB Revision

AUTOMATIC TRANSAXLE

23C-109

STEP 9. Erase the DTC code, and drive the vehicle for a 
while.
Check that the normal code is displayed.
Q: Is the check result normal?

YES : The procedure is complete.
NO :  Return to START.

DTC P0893: Interlock Detection

.

DESCRIPTIONS OF MONITOR METHODS

When sudden deceleration (2.5 m/s

2

) exceeding the 

setting time is detected with combination as follows; 
Stoplight switch: correct, output shaft speed sensor: 
correct, hydraulic switch: incorrect.

.

LOGIC FLOW CHARTS (Monitor Sequence)

.

DTC SET CONDITIONS

Check Conditions

• Fluid pressure switch status combination: not 

designed combination

• Stoplight switch signal: OFF.

Judgement Criteria

• Deceleration: more than threshold value. (1.9 

second)

.

OBD-II DRIVE CYCLE PATTERN

Start the engine, drive at 60 km/h (37.3 mph) or more 
for 15 minutes in total.

.

TROUBLESHOOTING HINTS (THE MOST 
LIKELY CAUSES FOR THIS CODE TO BE 
SET ARE:)

• Malfunction of the P0720: output shaft speed 

sensor system circuit

• Damaged harness or connector

• Malfunction of the P0743: lock-up and 

low-reverse brake linear solenoid valve system 
circuit

• Malfunction of the P0753: low clutch linear sole-

noid valve system circuit

• Malfunction of the P0758: 2-6 brake linear sole-

noid valve system circuit

• Malfunction of the P0763: 3-5 reverse clutch lin-

ear solenoid valve system circuit

• Malfunction of the P0768: high clutch linear sole-

noid valve system circuit

AUTOMATIC TRANSAXLE DIAGNOSIS <A/T>

TSB Revision

AUTOMATIC TRANSAXLE

23C-111

• Malfunction of the P1753: low clutch shift sole-

noid valve system circuit

• Malfunction of the P1758: low-reverse brake shift 

solenoid valve system circuit

• Malfunction of the P0846: 2-6 brake pressure 

switch system circuit

• Malfunction of the P0876: high clutch pressure 

switch system circuit

• Malfunction of the P0988: low-reverse brake 

pressure switch system circuit

DIAGNOSIS

STEP 1. Check the DTC.
Check if the following DTCs are set.

• P0720 output shaft speed sensor

• P0743 lock-up and low-reverse brake linear solenoid valve

• P0753 low clutch linear solenoid valve

• P0758 2-6 brake linear solenoid valve

• P0763 3-5 reverse clutch linear solenoid valve

• P0768 high clutch linear solenoid valve

• P1753 low clutch shift solenoid valve

• P1758 low-reverse brake shift solenoid valve

• P0846 2-6 brake pressure switch

• P0876 high clutch pressure switch

• P0988 low-reverse brake pressure switch

Q: Is the check result normal?

YES : Go to Step 2.
NO :  Repair or replace the failure section.

STEP 2. Check TCM related to the solenoid, pressure 
switch and output shaft speed sensor, the A/T control 
solenoid valve assembly connector pin terminals, and the 
connection status. 
Q: Is the check result normal?

YES : Replace the TCM, and then go to Step 3.
NO :  Repair or replace the failure section.

STEP 3. Erase the DTC code, and drive the vehicle for a 
while.
Check that the normal code is displayed.
Q: Is the check result normal?

YES : The procedure is complete.
NO :  Replace the transaxle assembly.

DTC P0988: Low-Reverse Brake Pressure Switch System

.

PRESSURE SWITCH SYSTEM CIRCUIT

Refer to 

P.23C-100

.

.

DESCRIPTIONS OF MONITOR METHODS

• During reverse driving, the switch OFF status 

continues for 2 seconds. (The detection is 
achieved twice during 1 driving cycle

*1

, and it 

continues for 2 driving cycles.)

*1

: Indicates the series of driving cycle "ignition 

key OFF 

→ ON → drive → OFF." The "1 driving 

cycle," "2 driving cycle," and so on indicates how 
many cycles are required to detect a failure.

.

MONITOR EXECUTION

• Reverse gear driving

.

Other Monitor (There is no temporary DTC stored 

in memory for the item monitored below)

• Not applicable
