1Battery voltage check
1) Measure voltage on battery.
Is voltage in 9 – 16 V?Go to Step 2. Check charging system
and repair as necessary
referring to “Generator
Test (Undercharged
Battery Check) in
Section 1J” or
“Generator Test
(Overcharged Battery
Check) in Section 1J”.
2Connection check
1) Check for loose each connection.
Is it connected securely?Go to Step 3. Intermittent trouble.
Check for intermittent
trouble referring to
“Inspection of
Intermittent and Poor
Connections” If OK,
substitute a known-
good SDM and recheck.
3Circuit fuse check
1) With ignition switch turn OFF, check “A/B” fuse for
blowing.
Is “A/B” fuse in good condition?Go to Step 4. Repair defective wire
circuit. After repaired,
replace “A/B” fuse.
