Customer Complaint Analysis
Record details of the problem (failure, complaint) and how it occurred as described by the customer.
For this purpose, use of such a questionnaire form as shown in figure will facilitate collectin g information to the point
required for proper analysis and diagnosis. Customer questionnaire (example)
Problem Symptom Confirmation
Check if what the custom er claimed in “Customer
Questionnaire” is accurately f ound in the vehicle. If that
symptom is found, check whether the symptom is
identified as a failure. (This step should be shared with
the customer if possible.)
DTC Check
Check DTC stored in BCM me mory referring to “DTC
Check”, record it and then clear it referring to “DTC
Clearance”. DTC indicates malfunction that occurred in
the system but does not indicate whether it exists now or
it occurred in the past and the normal condition has been
restored now. To check which case applies, clear DTC
once and check whether or not any fault exists.
Troubleshooting for DTC
Based on the DTC indicated in Step 3 and referring to
applicable DTC flow, locate the cause of the trouble,
namely in a sensor, wire harness, connector, BCM or
other part and repair or replace faulty parts. Body Electrical Control System Symptom Diagnosis
Check the parts or system
suspected as a possible
cause referring to symptom diagnosis of each system.
Check for Intermi ttent Problem
Check parts where an intermit tent trouble is easy to
occur (e.g., wire harness, connector, etc.), referring to
“Intermittent and Poor Connec tion Inspection in Section
00”.
Final Confirmation Test
Confirm that the problem symptom has gone and the
body electrical control system is free from any abnormal
conditions. If what has been repaired is related to the
malfunction DTC, check DTC again and confirm that no
DTC is indicated.

DTC B1133 (DTC No. 1133): Battery Voltage Too HighS7RS0BA204008
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.

• 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.
