TROUBLESHOOTING CHART
OPERATION PROCEDURE
- Connect both battery cables. NOTE: Supply power using jumper cables if battery is discharged.
- Use the Intelligent Key or mechanical key to turn the ignition switch to the "ACC" position. At this time, the steering lock will be released.
- Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
- Perform the necessary repair operation.
- When the repair work is completed, return the ignition switch to the "LOCK" position before connecting the battery cables. (At this time, the steering lock mechanism will engage.)
- Perform a self-diagnosis check of all control units using CONSULT-III.

Description
| Selection points | Selection parts | Selection items | Selection methods |
|---|---|---|---|
| Between cylinder block and crankshaft | Main bearing | Main bearing grade (bearing thickness) | Determined by match of cylinder block bearing housing grade (inner diameter of housing) and crankshaft journal grade (outer diameter of journal) |
| Between crankshaft and connecting rod | Connecting rod bearing | Connecting rod bearing grade (bearing thickness) | Combining service grades for connecting rod big end diameter and crankshaft pin outer diameter determine connecting rod bearing selection. |
| Between cylinder block and piston | Piston and piston pin assembly (piston is available together with piston pin as an assembly.) | Piston grade (piston outer diameter) | Piston grade = cylinder bore grade (inner diameter of bore) |
| Between piston and connecting rod (1) | |||
| (1) For the service parts, the grade for fitting cannot be selected between piston pin and connecting rod. (Only grade "0" is available.) The information at the shipment from the plant is described as a reference. | |||

COMPONENTS DESCRIPTION
- The identification grade stamped on each part is the grade for the dimension measured in new condition. This grade cannot apply to reused parts.
- For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the measurement with the values of each selection table.
- For details of the measurement method of each part, the reuse standards and the selection method of the selective fitting parts, refer to the text.
Scheme 7
- Check the cylinder bore grade on rear left side of cylinder block, and select piston of the same grade.
- If there is a corrected stamp mark on the cylinder block, use it as a correct reference.
Scheme 8
- Measure the cylinder bore inner diameter. Refer to " «INSPECTION»(ref-295108-S28407779032008081400000) ".
- Determine the bore grade by comparing the measurement with the values under the cylinder bore inner diameter of the "Piston Selection Table".
- Select piston of the same grade.
