Diagnosis:

SI-DRIVE mode does not switch.

CAUTION: Note that SI-DRIVE system operates the following controls when it switches the modes.

When turning the engine OFF and then ON again, it switches to I (intelligent) mode regardless of the mode before turning off the engine.
Switches to I (intelligent) when the malfunction indicator light illuminates while the engine is running. In this case, it will not be possible to change to the S (Sports) or S# (Sport Sharp) mode.

CHECK SI-DRIVE SWITCH .
1. Turn the ignition switch to OFF.
2. Disconnect the connector from the combination meter.
3. Measure the resistance when the SI-DRIVE switch is operated.
  Connector & terminal
  
  (i10) No. 35 - Chassis ground:
Does the resistance change as below?

I: Less than 1 Ω

S or S#: 1.71 - 1.89 kΩ

Yes

Go to 7 .

No

Go to 2 .
CHECK HARNESS BETWEEN COMBINATION METER AND SI-DRIVE SWITCH CONNECTOR (SHORT TO GROUND) .
CAUTION: Before handling the airbag system components, refer to "CAUTION" of "General Description" in "AIRBAG SYSTEM". Ref. to AIRBAG SYSTEM>GENERAL DESCRIPTION>CAUTION .
1. Remove the driver's airbag module. Ref. to AIRBAG SYSTEM>DRIVER'S AIRBAG MODULE>REMOVAL .
2. Measure the resistance between combination meter connector and chassis ground.
  Connector & terminal
  
  (i10) No. 35 - Chassis ground:
Is the resistance 1 MΩ or more?

Yes

Go to 3 .

No

Repair the short circuit to ground in harness between combination meter and SI-DRIVE switch connector.
CHECK HARNESS BETWEEN COMBINATION METER AND ROLL CONNECTOR (OPEN) .
1. Disconnect the connector from the roll connector.
2. Measure the resistance of harness between combination meter connector and roll connector.
  Connector & terminal
  
  (i10) No. 35 - (i72) No. 3:
Is the resistance less than 1 Ω?

Yes

Go to 4 .

No

Repair the open circuit of harness between combination meter connector and roll connector.
CHECK HARNESS BETWEEN ROLL CONNECTOR AND CHASSIS GROUND (OPEN) .
Measure the resistance of harness between roll connector and chassis ground.

Connector & terminal

(i72) No. 2 - Chassis ground:

Is the resistance less than 1 Ω?

Yes

Go to 5 .

No

Repair the following item.
- Open circuit in harness between roll connector and chassis ground
- Poor contact of J/C
CHECK SI-DRIVE SWITCH .
Check the SI-DRIVE switch. Ref. to EYESIGHT>SWITCHES AND HARNESS>INSPECTION .

Is the check result OK?

Yes

Go to 6 .

No

Replace the satellite switch assembly. Ref. to EYESIGHT>SWITCHES AND HARNESS>REMOVAL .

CHECK ROLL CONNECTOR .

Measure the resistance between roll connector terminals.

Terminal No.	Inspection conditions	Standard
A7 - C2	Always	Less than 1 Q
A8 - C3	Always	Less than 1 Q

Is the check result OK?

Yes

The circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.

NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.

Replace the roll connector. Ref. to AIRBAG SYSTEM>ROLL CONNECTOR>REMOVAL .

RECHECK FAULT .
1. Connect all connectors.
2. Switch SI-DRIVE modes.
Is there any fault?

Yes

Repair the poor contact of combination meter connector. Replace the meter case assembly if defective. Ref. to INSTRUMENTATION/DRIVER INFO>COMBINATION METER .

No

The circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.

NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.
