(i59) No. 10 (+) — Chassis ground (?):

Is the voltage 10 V or more?

INSTRUMENTATION/DRIVER INFO > Clock System > INSPECTION

Check the harness for a open or short between the fuse and clock.

2.CHECK GROUND CIRCUIT.

Measure the resistance between the clock connector and chassis ground.

Connector & terminal

(i59) No. 6 — Chassis ground:

Is the resistance less than 10 ??

INSTRUMENTATION/DRIVER INFO > Clock System > INSPECTION

Repair or replace the harness.

3.CHECK HARNESS BETWEEN CLOCK AND COMBINATION METER.

1) Disconnect the combination meter connector.

2) Measure the resistance between the clock connector and combination meter connector.

Connector & terminal

(i59) No. 5 — (i10) No. 29:

Is the resistance less than 10 ??

INSTRUMENTATION/DRIVER INFO > Clock System > INSPECTION

Repair or replace the harness.

3. CHECK AMBIENT TEMPERATURE METER SYSTEM COMMUNICATION CIRCUIT

STEPCHECKYESNO

1.CHECK AMBIENT SENSOR POWER SUPPLY.

1) Disconnect the ambient sensor connector.

2) Turn the ignition switch to ON.

3) Measure the voltage between the ambient sensor connector and chassis ground.

Connector & terminal

(F78) No. 2 (+) — Chassis ground (?):

Is the voltage 4 V or more?

INSTRUMENTATION/DRIVER INFO > Clock System > INSPECTION

Check the harness for a open or short between the fuse and clock.

2.CHECK HARNESS BETWEEN AMBIENT SENSOR AND COMBINATION METER.

1) Disconnect the combination meter connector.

2) Measure the resistance between the ambient sensor connector and the combination meter connector.

Connector & terminal

(F78) No. 1 — (i10) No. 23:

Is the resistance less than 10 ??

INSTRUMENTATION/DRIVER INFO > Clock System > INSPECTION

Repair or replace the harness.

3.CHECK AMBIENT SENSOR.

1) Remove the ambient sensor. HVAC SYSTEM (HEATER, VENTILATOR AND A/C) > Ambient Sensor (Auto A/C Model) > REMOVAL

2) Check the ambient sensor. HVAC SYSTEM (AUTO A/C) (DIAGNOSTICS) > Diagnostic Procedure for Sensors > AMBIENT SENSOR

Is the ambient sensor operating properly?

INSTRUMENTATION/DRIVER INFO > Clock System > INSPECTION

Replace the ambient sensor.

4.CHECK AMBIENT TEMPERATURE DISPLAY.

1) Connect the combination meter connector.

2) Install the 3 k? resistance to ambient sensor connector terminal.

3) Turn the ignition switch to ON.

Connector & terminal

(F78) No. 1 — No. 2:
