Diagnostic Procedure
DIAGNOSTIC PROCEDURE
| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK LAN SYSTEM. Inspect LAN system. |
Is LAN system normal? | Go to step 2 . | Perform the inspection according to the diagnosis for LAN system. |
| 2 CHECK FUSE. Remove the fuse. |
Is the fuse OK? | Go to step 3 . | Replace the fuse. When the replaced fuse is blown immediately, check the power supply circuit for short-circuited. |
3 CHECK HARNESS.
|
Is the resistance less than 1 Ω? | Go to step 4 . | Repair or replace the open circuit of harness. |
| 4 CHECK HARNESS. Using a tester, measure the resistance between the keyless access CM connector and chassis ground. Connector & terminal (B572) No. 11 - Chassis ground: |
Is the resistance less than 1 Ω? | Go to step 5 . | Repair or replace the open circuit of harness. |
| 5 CHECK HARNESS. Using a tester, measure the resistance between the keyless access CM connector and chassis ground. Connector & terminal (B572) No. 7 - Chassis ground: |
Is the resistance 10 kΩ or more? | Go to step 6 . | Repair or replace the short circuit of the harness. |
6 CHECK KEYLESS ACCESS CM.
|
Is the voltage 2 V or less → 9 V or more when the push button ignition switch is turned on while depressing the brake pedal with the shift position in P or N and while the key is in the passenger room? | Perform inspection according to the diagnosis of engine. < Refer to PROCEDURE , Basic Diagnostic Procedure. > | Replace the keyless access CM. < Refer to KEYLESS ACCESS CM . > |
