Is the problem found?
 | ▶ Repair the trouble causing part and go to "Verification of Vehicle Repair". |
 | ▶ Go to "Control Circuit Inspection". |
Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various problems and damge of component.
Perform checking procedure as follows.
Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.
Check connecting condition of ECM and component connector : Check terminal seperation, damage of locking device and connecting condition between terminal and wiring.
Disconnect the pin which requires checking at male connector and insert it to the terminal at female connector for checking connecting condition. ( after checking, reconnect the pin at correct position. )

| ▶ Go to "Control Circuit Inspection". |
Check control circuit voltage
IG KEY "OFF", ENGINE "OFF".
Disconnect ECM connector.
IG KEY "ON".
Measure the voltage between engine MIL terminal of ECM harness connector and chassis ground.
Specification : 10.8V~13.0V
Is the measured voltage within the specification?
| ▶ Go to "2. Grounding test of check lamp control circuit" as follows. |
| ▶ Check open in filament of check lamp. ( Refer to Component Inspection ) ▶ Repair open between power terminal of cluster and ECM harness connector and go to "Verification of Vehicle Repair", |
Grounding test of check lamp control circuit
IG KEY "OFF", ENGINE "OFF".
Disconnect ECM connector.
IG KEY "ON".
Ground MIL terminal of ECM harness connector to chassis ground.
Specification : check lamp turns ON.
Does check lamp turn ON?
| ▶ Go to "Verification of Vehicle Repair". |
| ▶ Repair short to battery in check lamp control circuit and go to "Verification of Vehicle Repair". |
