1. Outside air temperature sensor
DTC detecting condition Possible cause
DTC B1141 (DTC No. 1141):
Input signal from outside air temperature sensor is higher
than 4.88 V.• Open in outside air temperature sensor circuit
• Outside air temperature sensor malfunction
• BCM malfunction
DTC B1142 (DTC No. 1142):
Input signal from outside air temperature sensor is lower
than 0.1 V.• Short in outside air temperature sensor circuit
• Outside air temperature sensor malfunction
• BCM malfunction
Step Action Yes No
1 Outside air temperature sensor check
1) Turn ignition switch to OFF position.
2) Disconnect connector from outside air temperature
sensor.
3) Check outside air temperature sensor for resistance
referring to “Outside Air Temperature Sensor Inspection
(If Equipped) in Section 9C”.
Is it in good condition?Go to Step 2. Replace outside air
temperature sensor.
2Outside air temperature sensor circuit check
1) Disconnect connector from BCM and check for proper
terminal connection to BCM connector.
2) If connections are OK, check outside air temperature
sensor circuit for open, short and high resistance.
Is each circuit in good condition?Substitute a known-
good BCM (included in
junction block) and
recheck.Repair circuit.

5) Disconnect connectors from BCM and junction
block.
6) Detach wiring harness clamp from junction block.
Installation
Reverse removal procedure for installation, noting
following points.
• Connect connectors securely.
• Enable air bag system referring to “Enabling Air Bag
System in Section 8B”.
• With keyless entry system (other than keyless start
model), if BCM is replaced, register transmitter code
into BCM, referring to “Programming Transmitter
Code for Keyless Entry System (Other than Keyless
Start Model) in Section 9F”.
Security Alarm Mode Selection Procedure (If
Equipped)
S6RW0DA206005
Security alarm mode can be selected by performing the
following procedure.
1) Confirm that all doors are closed, all doors are
unlocked and ignition key is inserted in ignition key
cylinder.
2) Remove ignition key from ignition key cylinder.
3) Perform Step a) through e) described below within
15 seconds.
a) Insert ignition key (1) in ignition key cylinder (2).
b) Remove ignition key from ignition key cylinder.
c) Repeat Step a) and b) twice.
d) Insert ignition key in ignition key cylinder.
e) Push lock side (3) of driver side manual lock
switch (4) 3 times.4) When Step 3) is completed, the mode changes to
the next one automatically. The warning buzzer
(located in BCM) sounds by the number of specified
for each mode as follows.
• Changed from A mode to B mode: Buzzer sounds
4 times
• Changed from B mode to A mode: Buzzer sounds
once
