- Step 1
SET IN SELF-DIAGNOSIS MODE
- a
Turn ignition switch ON.
- b
Set in self-diagnosis mode as follows. Within 10 seconds after starting engine (ignition switch is turned
ON.), press OFF switch for at least 5 seconds.
- Step 2
SENSOR CIRCUITS ARE CHECKED FOR OPEN OR SHORT CIRCUIT

- Step 4
OPERATION OF EACH DOOR MOTOR IS CHECKED
- a
Press temperature (UP) switch (driver side).
- b
Press (DEF) switch. Code No. of each door motor test is indicated on the display.
- Step 5
TEMPERATURE OF EACH SENSOR IS CHECKED
- a
Press temperature (UP) switch (driver side).
- b
Code No. 51 appears on the display.
- c
Press (DEF) switch one time. Temperature detected by ambient sensor is indicated on the display.
- Note:
If temperature shown on display greatly differs from actual temperature, check sensor circuit first, then inspect sensor.
- c
Press (DEF) switch a second time. Temperature detected by invehicle sensor is indicated on the display.
- Note:
If temperature shown on display greatly differs from actual temperature, check sensor circuit first, then inspect sensor.
- c
Press (DEF) switch a third time. Temperature detected by intake sensor is indicated on the display.
- Note:
If temperature shown on display greatly differs from actual temperature, check sensor circuit first, then inspect sensor.
