NOTE: When the measured resistance value is more than 52 Ω and less than 62 Ω, main wiring harness or related lines may be shorted to ground, or shorted to power supply line, or related lines may be open.

CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS .
1. Turn the ignition switch to OFF.
2. Disconnect the audio or navigation unit connector.
3. Using a tester, measure the resistance between audio or navigation unit connector and chassis ground.

  (i87) No. 9 - Chassis ground:
  
  (i87) No. 10 - Chassis ground:
Is the resistance less than 10 Ω?

Yes : Go to 2.

No : Go to 3.
CHECK CONTROL MODULE .
With the tester connected, disconnect control module.

NOTE: Disconnect the central gateway Control Module at the end.

(i87) No. 9 - Chassis ground:

(i87) No. 10 - Chassis ground:

Did the resistance change to 10 Ω or more?

Yes : Replace the control module whose resistance has changed. When the value changed at disconnecting the central gateway Control Module, replace the central gateway Control Module. Ref. to SECURITY AND LOCKS>GATEWAY Control Module . Go to 3.

No : Repair or replace the short circuit of the harness between the central gateway Control Module and body integrated unit.
CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS .
1. Turn the ignition switch to ON.
2. Using a tester, measure the voltage between audio or navigation unit connector and chassis ground.
  Connector & terminal
  
  (i87) No. 9 (+) - Chassis ground (-):
  
  (i87) No. 10 (+) - Chassis ground (-):
Is the voltage 5 V or less?

Yes : CAN communication circuit is normal.

No : Go to 4.
CHECK CONTROL MODULE .
With the tester connected, disconnect control module.

NOTE: Disconnect the central gateway Control Module at the end.

Connector & terminal

(i87) No. 9 (+) - Chassis ground (-):

(i87) No. 10 (+) - Chassis ground (-):

Did the voltage change to 5 V or less?

Yes : Replace the control module whose voltage has changed. When the value changed at disconnecting the central gateway Control Module, replace the central gateway Control Module. Ref. to SECURITY AND LOCKS>GATEWAY Control MODULE . Go to 5.

No : Repair or replace the short circuit of the harness between the central gateway Control Module and body integrated unit.
CHECK HARNESS .
Using a tester, measure the voltage between the central gateway Control Module connector and chassis ground.

(i366) No. 15 (+) - Chassis ground (-):

(i366) No. 16 (+) - Chassis ground (-):

Is the voltage 5 V or less?

Yes : CAN communication circuit is normal.

No : Repair or replace the short circuit of the harness between the central gateway Control Module and body integrated unit.
