| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK LAN SYSTEM. Inspect LAN system. Ref. to PROCEDURE , Basic Diagnostic Procedure. |
Is the check result OK? | Go to step 2 | Perform the inspection according to the diagnosis for LAN system. |
| 2 CHECK FUSE. Check the fuse. Ref. to RELAY AND FUSE |
Is the check result 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 (OPEN CIRCUIT).
|
Is the resistance less than 1 Ω? | Go to step 4 | Repair or replace the open circuit of harness. |
| 4 CHECK HARNESS (OPEN CIRCUIT). Using a tester, measure the resistance between the keyless access Control Module connector and chassis ground. Connector & terminal (i241) No. 21 - Chassis ground: (i75) No. 1 - Chassis ground: |
Is the resistance less than 1 Ω? | Go to step 5 | Repair or replace the open circuit of harness. |
| 5 CHECK HARNESS (GROUND SHORT CIRCUIT). Using a tester, measure the resistance between the keyless access Control Module connector and chassis ground. Connector & terminal (i241) No. 35 - 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 CONTROL MODULE.
|
Does the voltage change as 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 (AT model) or while depressing clutch pedal (MT model)? | Perform inspection according to the diagnosis of engine. Ref. to PROCEDURE , Diagnostics for Engine Starting Failure. Ref. to PROCEDURE , Diagnostics for Engine Starting Failure. | Replace the keyless access Control Module.
