Check Clock System Communication Circuit

1. Disconnect the MFD connector.
2. Turn the ignition switch to ON.
3. Measure the voltage between MFD connector and chassis ground.

Connector & terminal 

(i122) No. 3 (+) - Chassis ground (-):

Is the voltage 10 V or more?

• Yes: Go to 2  .
• No: Repair or replace the harness.

Measure the resistance between MFD connector and chassis ground.

Connector & terminal 

(i122) No. 2 - Chassis ground:

Is the resistance less than 10 Ω?

• Yes: Go to 3  .
• No: Repair or replace the harness.

1. Remove the MFD.
2. Attach the clock to another vehicle on which the clock display operates normally, and check its operation.

Is MFD normal?

• Yes: Repair the poor contact of connector.
• No: Replace the MFD.
