Code No. P0893: Interlock Detection
DIAGNOSIS CODE SET CONDITIONS
- With the stop lamp switch signal and output shaft speed sensor being normal, the fast deceleration exceeding the set time is detected.
- Output failure to the solenoid, open or short circuit
- Hydraulic switch pattern, hydraulic switch open or short circuit
- Open circuit of the output shaft speed sensor or poor connection of the connector
PROBABLE CAUSES
- 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 solenoid valve system circuit
- Malfunction of the P0758: 2-6 brake linear solenoid valve system circuit
- Malfunction of the P0763: 3-5 reverse clutch linear solenoid valve system circuit
- Malfunction of the P0768: high clutch linear solenoid valve system circuit
- Malfunction of the P1753: low clutch shift solenoid valve system circuit
- Malfunction of the P1758: low-reverse brake shift solenoid valve system circuit
- Malfunction of the P0841: low clutch pressure switch system circuit
- Malfunction of the P0846: 2-6 brake pressure switch system circuit
- Malfunction of the P0871: 3-5 reverse clutch 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 PROCEDURE |
STEP 1. Check the diagnosis code. |
Check if the following diagnosis codes are set. |
|
Q.
Is the check result normal?
|
Go to Step 2. |
|
Repair or replace the failure section. |
|
STEP 2. Check A/T-ECU 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?
|
Replace the A/T-ECU, and then go to Step 3. |
|
Repair or replace the failure section. |
|
STEP 3. Erase the diagnosis code, and drive the vehicle for a while. |
Check that the normal code is displayed. |
Q.
Is the check result normal?
|
The procedure is complete. |
|
Replace the transmission assembly. |
