Has a problem been found?
 | ▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure. |
 | ▶ Go to "Check Charging system" procedure. |
Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
Has a problem been found?
| ▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure. |
| ▶ Go to "Check Charging system" procedure. |
ENG "ON" and Turn On the electrical load such as Head light and Heater.
Check battery voltage(+) and (-) after accellerating 2500 engine RPM at idle status for 2 min.
Specification : About 9 ≤ Vbatt ≤ 16
Is the measured voltage within specification ?
| ▶ Go to "Power Circuit Inspection" procedure. |
| ▶ Check Fuse from Alternator to battery and connection of connector and harness. And then, go to "Verification of Vehicle Repair" procedure. ▶ If harness connection is O.K, howerever, over voltage is detected, repair or replace alternator and then, go to "Verification of Vehicle Repair' procedure. |
IG "OFF".
Wait for 1 min. after disconnecting battery (-) cable.
Disconnect IPM connector.
IG "ON" after connecting battery (-) terminal.
Measure voltage between ON/START terminal of IPM harness connector and chassis ground.
Specification : About 9 ≤ Vbatt ≤ 16
Is the measured voltage within specification ?
| ▶ Go to "Ground Circuit Inspection" procedure. |
| ▶ Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure. |
IG "OFF".
Wait for 1 min. after disconnecting battery (-) terminal.
Disconnect IPM connector.
Measure resistance between Ground Terminal of IPM harness connector and chassis ground.
Specification : About below 1 Ω.
Is the measured value within specification ?
| ▶ Substitute with a known - good IPM and check for proper operation. If the problem is corrected, replace the IPM and go to "Verification of Vehicle Repair" procedure. |
| ▶ Check open in harness and repair or replace as necessary and then, go to "Verification of Vehicle Repair" procedure. |
