Component Tests and General Diagnostics
ON-VEHICLE INSPECTION1. INSPECT WIRELESS DOOR LOCK CONTROL FUNCTIONS
HINT:
- The switch described below transmit signals and are built into the door control transmitter.
- The transmitter's operational area must be taken into account while checks are being made.
a. Make sure the vehicle is in the initial condition described below.
1. The followings are the vehicle's initial condition.
- No key in the ignition key cylinder
- All the doors closed (door open indicator off)
- All the doors locked
b. Check the basic function.
1. In the operational area, check that all the doors lock when pressing the LOCK switch.
2. Check that the driver's door unlocks when pressing the UNLOCK switch and pressing the switch once again within 3 seconds unlocks all the other doors.
HINT: The UNLOCK operation is possible even when any of the doors is open.
c. Check the chattering prevention function.
1. If a switch is pressed, check that the corresponding operation occurs only once. If the switch is held down, check that the corresponding operation occurs only once and does not repeatedly activate. Lastly, if a switch is pressed at 1 second intervals, check that the corresponding operation activates once for every press of the switch.
d. Check the automatic locking function.
1. Check that if all of the doors are unlocked with the UNLOCK switch and none of the doors are opened or locked within approximately 30 seconds, the doors automatically relock.
2. Check that if all of the doors are unlocked with the UNLOCK switch and a door is opened or locked within approximately 30 seconds, the automatic locking function does not operate.
e. Check the switch operation fail-safe function.
1. Check that when the key is in the ignition cylinder, the switches cannot lock or unlock doors (unless the system is in the recognition code registration mode).
f. Check the repeat function.
1. If the lock switch is pressed while the movement of the driver side door control knob is restricted, check that, 1 second later, the repeat function attempts to lock all of the doors again.
g. Check the operation stop function when a door is open or not completely close.
1. If a door is open or not completely closed, check that: 1) the doors cannot be locked by the LOCK switch and buzzer sounds for 10 seconds, and 2) the glass hatch open operation is possible.
h. Check the hazard warning lights flashing function (answer back).
1. Check that when a switch is pressed: 1) the doors lock or unlock, and 2) the hazard warning lights flash and the buzzer sounds once (when locking) or twice (when unlocking).
i. Check the glass hatch open function.
1. Check that when the HATCH switch has been pressed for approximately 10.8 seconds, the glass hatch will open.
HINT: The open operation is possible even when any of the doors is open.
j. Check the remote panic function.
1. Check that the theft alarm sounds and headlights and tail lights flash when the PANIC switch is pressed, and that sounding and flashing stop when the PANIC or UNLOCK switch is pressed once again.
2. CHECK DOOR CONTROL RECEIVER
a. Disconnect the connector from the door control receiver.
b. Measure the resistance and voltage between the terminals of the door control receiver connector and the body ground.
If the result is not as specified, there may be a malfunction on the wire harness side.
c. Reconnect the connector and check the voltage between the terminal and the body ground.
If the result is not as specified, the door control receiver has a malfunction.
