DTC P0893: Interlock Detection

DESCRIPTIONS OF MONITOR METHODS
^ With the stoplight 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

MONITOR EXECUTION
^ Continuous

LOGIC FLOW CHARTS (Monitor Sequence)

Logic Flow Charts (Monitor Sequence):

DTC SET CONDITIONS

Check Conditions
^ Pattern of hydraulic pressure switch: incorrect combination.
^ Output shaft speed sensor: normal.
^ Stoplight switch signal: normal.

Judgement Criteria
^ Deceleration: more than 2.5 m/s (squared). (0.3 second)

OBD-II DRIVE CYCLE PATTERN
Start the engine, drive at 60 km/h (37 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 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

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
^ P0841 low clutch pressure switch
^ P0846 2-6 brake pressure switch
^ P0871 3-5 reverse clutch 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.
