Diagnostic Procedure: Control Module Power Supply/Ground

Step 1 - 2:

E : DIAGNOSTICS PROCEDURE FOR SECURITY CONTROL MODULE POWER SUPPLY/GROUND CIRCUIT

1. CHECK FUSE AND POWER SUPPLY CIRCUIT.
1. Check fuse No.25.




2. Measure voltage between main fuse box connector and body.

Connector & terminal / Specified voltage:
(F35) No. 2 - Body / 10 V, or more




3. Disconnect connector from security control module.
4. Measure voltage between security control module connector and body.

Connector & terminal / Specified voltage:
(B93) No.8 - Body / 10 V, or more




5. Check fuse No.3.
6. Turn ignition switch to ACC.
7. Measure voltage between fuse and relay box connector and body.

Connector & terminal / Specified voltage:
(i5) No.13 - Body / 10 V, or more







8. Disconnect connector from security control module.
9. Measure voltage between security control module connector and body.

Connector & terminal / Specified voltage:
(B93) No.6 - Body / 10 V, or more

2. CHECK GROUND CIRCUIT BETWEEN SECURITY CONTROL MODULE AND BODY.




1. Turn ignition switch to OFF.
2. Disconnect connector of security control module.
3. Measure resistance of harness connector between security control module and body.

Connector & terminal / Specified resistance:
(B93) No.9 - Body / 10 Ohm, max.
