Checking the main switch
Check the main switch circuit as shown in the table.
If—conductivity—is different—from specification, replace the switch.
Checking the central locking switch (in the door lock)
Models up to 1996
1. Check for continuity between terminals "2" And "3" connector when the switch is in the position "blocked".
2. Check for continuity between terminals "1" And "2" connector when the switch is in the position "unlocked".
Models after 1996
1. Check for continuity between terminals "2" And "3" connector when the switch is in the position "blocked".
2. Check for continuity between terminals "1" And "3" connector when the switch is in the position "unlocked". Replace the switch if the continuity of the circuits is broken.
Checking the tailgate lock switch (station wagon)
Check conductivity.
Checking the door lock motor
Models up to 1996
1. Checking the operation of the electric drive of the front door lock.
- A) Connect the battery to the terminals "5" (+) And "7" (-) connector. Make sure the latch of the lock moves to the position "unlocked".
- b) Reverse the polarity of the battery connection, the latch of the door lock should move to the position "blocked". Replace the lock if it does not work as directed.
2. Checking the operation of the electric drive of the lock of the rear door and the tailgate (for station wagon models).
- A) Connect the battery to the terminals "2" (+) And "4" (-) connector. Make sure the latch of the lock moves to the position "unlocked".
- b) Reverse the polarity of the battery connection: the latch of the door lock must move and the position "blocked".
Models after 1996
1. Connect the battery to terminals 3 (+) and 2 (-), check that the latch of the lock has moved from the position "unlocked".
2. Reverse the polarity of the voltage, the latch should move to the position "blocked". Replace the lock if it does not work as directed.
Thermistor test
Note: In parentheses are pin numbers for models manufactured since 1996.
J Connect the battery "+" battery to the output "5" ("3") connector.
2. Connect the positive lead of the ammeter to the terminal "7" ('2"), ammeter negative lead to battery Check that the current changes from about 3.2A to less than 0.5A within 20-70 seconds.
3. Disconnect the wires from the connector.
4 After about 60 seconds, connect the battery to the terminals "5" ("2") (+) And "7" ("3") (-), the door latch should move to the position "blocked". If the work is not as described, replace the lock.
Checking the central locking control relay
Models up to 1996
Disconnect the connector from the relay and check the connector on the wire side as shown in the table.
Models after 1996
1. Disconnect the connector from the relay and check the connector on the wire side as shown in the table.
2. If the circuit matches the table and the problem persists, check the target with the connector connected (for models after 1996 release).
- A) Connect the connector to the relay.
- b) Connect the positive lead of the voltmeter to the terminal "8", negative to the conclusion "7".
- V) Set the central locking switch to position "unlocked". Check that the voltage changes from 0 to battery voltage in about 0.2 seconds.
- G) Reverse the polarity of the voltmeter connection.
- d) Set the central locking switch to position "blocked". Check that the voltage changes from 0 to battery voltage in about 0.2 seconds. If the operation is not as described, replace the relay.
Checking the unlocked door sensor
1. Check the conductivity.
- A) Check for continuity between terminals "4" And "6" at sensor position "OFF" (the door is locked).
- b) Check for continuity between terminals *4" And "6" at sensor position "ON" (the door is unlocked). If the conductivity is not as described, replace the lock.
2. Check the lock signal. Note: If relay operation is as described, check blocking signal.
- A) Connect the connector to the control relay.
- b) Connect the battery to the terminals "3" (+) And "1" (-) connector.
- V) Set the lock switch to the position "UNLOCK" (unlocked), check that the voltage rises from 0 to battery voltage in about 0.2 sec.
- G) Connect the battery to the terminals "4" (+) And "1" (-) connector.
- d) Set the lock switch to the position "LOCK" (blocked), check that the voltage rises from 0 to battery voltage in about 0.2 sec. If operation is not as described, replace the relay.
