- Engine type: FA
- Engine type: EJ
DIAGNOSTIC PROCEDURE
| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK LAN SYSTEM. Inspect LAN system. < Ref. to PROCEDURE , Basic Diagnostic Procedure. > |
Is LAN system normal? | 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 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 voltage 9.5 - 16 V? | Go to step 4. | Check the power supply circuit. |
| 4 CHECK HARNESS. Using a tester, measure the resistance between the keyless access CM (Control Module) 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.
|
Is resistance 74.15 - 460.88 Ω? (at 20°C) Go to step 6. | Check IG relay 2. | Go to step 7. |
6 CHECK HARNESS.
|
Is resistance 50.87 - 72.17 Ω? (20°C) | Go to step 8. | Check IG relay 1. Go to step 7. |
| 7 CHECK RELAY. Perform unit inspection of IG relay 1 and IG relay 2. < Ref. to CHECK RELAY , INSPECTION, Relay and Fuse. > |
Is the relay OK? | Go to step 8. | Replace the relay. < Ref. to REMOVAL , IG Relay1 (Push Button Start). > < Ref. to REMOVAL , IG Relay2 (Push Button Start). > |
8 CHECK KEYLESS ACCESS CM (Control Module).
|
Is the voltage 1 V or less → 9.5 - 16 V when ACC → IGN ON? | System is normal. It is possible that temporary poor contact occurs. | Replace the keyless access CM (Control Module). < Ref. to REMOVAL , Keyless Access CM (Control Module). > |
