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 SIDRIVE 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 Ω
A8 - C3	Always	Less than 1 Ω

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.

No: 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.
