DIAGNOSTICS - POWER SLIDE DOOR SYSTEM
05BZJ-01
PRE-CHECK
1. DIAGNOSIS SYSTEM
(a) Inspect the DLC3.
HINT:
1 2 3 4 5 6 7 8 The vehicle's ECM uses ISO 9141-2 for communication.
9 10 11 12 13 14 15 16 The terminal arrangement of the DLC3 complies with SAE
J1962 and matches the ISO 9141-2 format.
DLC3
B50154
Terminal No. Condition Specified Condition
7 (Bus + line) - 5 (Signal ground) During communication Pulse generation
4 (Chassis ground) - Body ground Constant Below 1
5 (Signal ground) - Body ground Constant Below 1
16 (B+) - Body ground Constant 9 to 14 V
HINT:
If the screen displays UNABLE TO CONNECT TO VEHICLE after you have connected the cable of the
hand-held tester to the DLC3, turned the ignition switch ON and used the hand-held tester, there is a prob-
lem on the vehicle side or tester side.
S If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the
original vehicle.
S If communication is still impossible when the tester is connected to another vehicle, the problem is
probably in the tester itself, so consult the Service Department listed in the tester's manual.
Hand-held Tester
2. CHECK DTC (USING HAND-HELD TESTER)
(a) Checking DTCs.
(1) Connect the hand-held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) Read DTCs by following the prompts on the tester
screen.
HINT:
Refer to the hand-held tester operator's manual for further de-
A80036 tails.
3. CLEAR DTC (USING HAND-HELD TESTER)
(a) Clearing the DTCs from memory.
(1) Connect the hand-held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) Erase the DTCs following the prompts on the tester
screen.
HINT:
Refer to the hand-held tester operator's manual for further de-
tails.

4. DATA LIST
HINT:
Using the DATA LIST displayed on the hand-held tester, you can read the value of the switch, sensor, actua-
tor, etc. without parts removal. Reading the DATA LIST as the first step of troubleshooting is one way to
shorten the labor time.
(a) Connect the hand-held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Read the DATA LIST according to the display on the tester.

5. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand-held tester allows you to operate the relay, VSV, actuator,
etc. without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one way to
shorten the labor time. It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Connect the hand-held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Perform the ACTIVE TEST according to the display on the tester.

6. RESET
(a) When the control motor and clutch is replaced:
The power slide door ECU cannot receive a switch signal from the control motor and clutch. This may
cause the power slide door system to enter fail-safe mode and DTC (B2224 (LH) or B2223 (RH)) to
set, and also make the system disabled.
When the motor and clutch is replaced, be sure to perform the following: first, properly connect the
motor and clutch; second, clear the DTC using the hand-held tester and finally recheck that no DTC
is output.
(b) Reset the power slide door system:
The power slide door ECU records the fully open position and the fully closed position of the power
slide door in its memory and the power slide door fully opens and closes based on this memory. The
power slide door cannot operate without this memory. In the case where the battery has been removed,
manually close the slide door fully to reset the power slide door system. However, if the battery is re-
moved/installed when the slide door is fully open, the power slide door operates normally, thus the re-
setting the system is unnecessary.
