HOW TO PROCEED WITH TROUBLESHOOTING
HINT:
Carry out troubleshooting in accordance with the procedures on the follo\
wing page. Here, only the basic
procedures are shown. Details are provided in the Diagnostics Section, showing the most effective methods
for each circuit. Confirm the troubleshooting procedures first for the r\
elevant circuit before beginning trouble-
shooting of that circuit.
1 Vehicle brought to workshop
2 Customer problem analysis
(a) Ask the customer about the conditions and environment when the problem o\
ccurred.
3 Symptom confirmation and DTC (and freeze frame data) check
(a) Check the battery positive voltage. Voltage: 11 ± 14 V (Engine stopped)
(b) Visually check the wire harness, connectors and fuses for open and short,\
etc.
(c) Warm up the engine to the normal operating temperature.
(d) Confirm the problem symptoms and conditions, and check for DTCs accordin\
g to the related chart.
OK Go to step 5
NG
4 DTC chart
(a) Check the results obtained in step 3, then confirm the inspection procedures \
for the system or the part which should be checked using the DTC chart.
Go to step 6
5 Problem symptoms chart
(a) Check the results obtained in step 3, then confirm the inspection procedures \
for the system or the partwhich should be checked using the problem symptoms table.
6 Circuit inspection or parts inspection
(a) Confirm the circuit for the system or the part which should be checked u\
sing the problem symptoms
table or the results obtained in step 4.
7 Repair
(a) Repair the affected system or part in accordance with the instructions in step 6.

The
”Current Flow Chart” section, describes which parts each power source (fuses, fusible links\
, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the condition\
s when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power so\
urce, the power source system must be fully
understood.
