Step Action YesNo
1 Fuse check
1) Turn ignition switch to OFF position.
2) Check circuit fuses for condition.
Are circuit fuses in good condition? Go to Step 2.
Replace fuse and check
for short circuit to
ground.
2 Power supply circuit check
1) Disconnect connectors from junction block assembly.
2) Check for proper connection to junction block assembly
connector at terminal “E40-2”.
3) If OK, then measure voltage between “E40-2” terminal of junction block assembly connector and vehicle body
ground.
Is voltage 10 – 14 V? Go to Step 3.
Repair power supply
circuit.

Wiring Diagram
Refer to “BCM Power Circuit and Ground Circuit Check”.
DTC Detecting Conditi on and Possible Cause
Flow Test Description
Step 1: Check charging system
DTC Troubleshooting 3
Power supply circuit check
1) Check for proper connection to junction block assembly
connector at terminals “G32-2” and “G32-5”.
2) If OK, turn ignition switch ON.
3) Measure voltage between following terminals. • Between “G32-2” terminal of junction block assembly connector and vehicle body ground
• Between “G32-5” terminal of junction block assembly connector and vehicle body ground
Is each voltage 10 – 14 V? Go to Step 4. Repair power supply
circuit.
4 Ground circuit check
1) Turn ignition switch to OFF position.
2) Check for proper connection to junction block assembly
connector at terminals “G33-3”, “G34-9” and “L05-4”.
3) If OK, then measure resistance between following terminals.
• Between “G33-3” terminal of junction block assembly connector and vehicle body ground
• Between “G34-9” terminal of junction block assembly connector and vehicle body ground
• Between “L05-4” terminal of junction block assembly connector and vehicle body ground
Is each resistance 2
Ω or less? BCM power supply
circuit and ground circuit
are in good condition.
Repair ground circuit.
Step Action Yes No
DTC detecting condition
Possible cause
Power voltage supplied from battery to BCM is
higher than 16V. • Charging system malfunction
• BCM malfunction
Step
Action YesNo
1 Charging system operation check
1) Check generator for operation referring to “Generator
Test (Overcharged Battery Check) in Section 1J”.
Is it in good condition? Substitute a known
good BCM (included in
junction block
assembly) and recheck.
Repair charging system.

2. BCM
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 YesNo
1 Check outside air temperature sensor
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.
