INSPECTION
|
ACTION
|
|
1
|
INSPECT OIL PRESSURE WARNING LIGHT
Disconnect the oil pressure switch connector.
Connect a jumper wire with a 10 A fuse between oil pressure switch terminal A (harness-side) and ground.
Turn the ignition switch to the ON position.
Does the oil pressure warning light illuminate?
|
Yes
|
Go to the next step.
|
|
No
|
Go to Step 3.
|
|
2
|
OIL PRESSURE INSPECTION
Inspect the oil pressure.
Is the engine oil pressure within specification?
|
Yes
|
Go to Step 5.
|
|
No
|
Refer to Section 01-11.
|
|
3
|
INSPECT FOR OPEN CIRCUIT
Disconnect the instrument cluster connector.
Measure the resistance between instrument cluster terminal 3D (harness-side) and oil pressure switch terminal A (harness-side).
Is the resistance less than 5 ohms?
|
Yes
|
Go to the next step.
|
|
No
|
Repair or replace the wiring harness. Inspect the system for normal operation.
|
|
4
|
INSPECT FOR SHORT TO POWER SUPPLY
Turn the ignition switch to the ON position.
Measure the voltage between instrument cluster terminal 3D (harness-side) and ground.
Is there voltage?
|
Yes
|
Repair or replace the wiring harness. Inspect the system for normal operation.
|
|
No
|
Go to Step 6.
|
|
5
|
INSPECT CIRCUIT FOR SHORT TO GROUND
Disconnect the instrument cluster connector.
Measure the resistance between instrument cluster terminal 3D (harness-side) and ground.
Is the resistance less than 5 ohms?
|
Yes
|
Repair or replace the wiring harness. Inspect the system for normal operation.
|
|
No
|
Replace the oil pressure switch. Inspect the system for normal operation.
|
|
6
|
INSPECT INSTRUMENT CLUSTER OPERATION
Disconnect all the instrument cluster connectors.
Inspection:
• Corrosion
• Terminal separation
Connect the instrument cluster connector and verify that its position is correct.
Operate the system and inspect for any malfunction.
Is any malfunction still present?
|
Yes
|
Replace the instrument cluster. Inspect the system for normal operation.
|
|
No
|
The system operates normally. The malfunction may result from loose connectors or corrosion. Clear the DTC. Repeat the self-test.
