Has a problem been found?
 | ▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure. |
 | ▶ Go to next procedure. |
Many malfunctions in the electrical system are caused by poor harness and terminals.
Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.

Engine "ON".
headight and heatwire "ON".
Measure voltage between terminal (+) and (-) of battery while maintaining ENG RPM 2,500RPM over 2 minutes.
Specification : Less than 17 [V]
Is "resistance" display near the specified value?
| ▶ Go to "Power Circuit Inspection" procedure. |
| ▶ Check that the tension of drive velt, ENG RPM, fuse, terminal of battery, all terminals of alternator are in good condition and Check for damaged harness and poor connection between alternator and battery. ▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure. |
IG Key "OFF".
Disconnect A. A. F connector.
IG "ON" & Engine "ON".
Measure voltage between terminal A. A. F harness connector and chassis ground.
Specification : less than 17 [V]
Is the measured voltage within specifications?
| ▶ Go to "Ground Circuit Inspection" procedure. |
| ▶ Check for open or blown fuse referring to "Circuit Diagram". Repair open or short in power circuit between battery and A.A.F harness connector and then go to "Verification of vehicle Repair" procedure. |
IG Key "OFF".
Disconnect A. A. F connector.
Measure resistance between terminal A.A.F harness connector and chassis ground.
Specification : Approx. 0 Ω
Is the measured resistance within specifications?
| ▶ Substitute with a known-good A.A.F and check for proper operation. If the problem is corrected,replace A.A.F and then go to "Verification of Vehicle Repair" procedure. |
| ▶ Check for open or contact resistance in ground harness. ▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure. |
