Inspection Procedure

WIRING DIAGRAM





PROCEDURE
1. Check voltage between terminals +B and E1 of engine control module connector.
- Turn up the floor mat on the passenger side.
- Turn ignition switch ON.




- Measure voltage between terminals +B and E1 of engine control module (ECM) connector.

OK: Voltage: 9 - 14 volts

^ If OK, proceed to next circuit inspection shown in the matrix chart in Diagnosis by Symptom under "Powertrain Management Testing Procedures".
Testing and Inspection
^ If NOT OK, proceed to step 2.

2. Check for open in harness and connector between terminal E1 of engine control module and body ground.
^ If OK proceed to step 3.
^ If NOT OK, repair or replace harness or connector.

3. Remove EFI main relay from R/B No.2. and check for continuity.



- Check continuity between terminals of EFI Main relay shown below.
OK: Terminals 3 and 5 - Open
Terminals 1 and 2 - Continuity
(reference value: 75 Ohms)
- Apply battery positive voltage between terminals 1 and 2.
- Check continuity between terminals 3 and 5.
OK: Terminals 3 and 5 - Continuity
^ If OK proceed to step 4.
^ If not OK, replace EFI Main relay.

4. Check IGN fuse.



- Remove IGN fuse from Inpane J/B.
- Check continuity of IGN fuse.
OK: Continuity

^ If OK proceed to step 5.
^ If not OK, check for short in all the harness and components connected to IGN fuse.
See included WIRING DIAGRAM

5. Check ignition switch.
- Remove finish panel lower No.1.
- Remove finish panel.



- Check continuity between terminals.

OK: Switch Terminal
Position Continuity
LOCK none
ACC - 5 - 7
ON - 2 - 3
and 4 - 5 - 7
START - 1 - 2 - 3
and 4 - 7 - 8
^ If OK proceed to step 6.
^ If not OK, replace ignition switch.

6. Check for open in harness and connector between ignition switch and EFI Main relay, EFI Main relay and body ground.
^ If OK proceed to step 7.
^ If not OK, repair or replace harness or connector.

7. Check EFI fuse.




- Remove EFI fuse from R/B No.2.
- Check continuity of EFI fuse.
OK: Continuity
^ If OK check for open in harness and connector between EFI Main relay and battery, EFI Main relay and ECM.
^ If not OK check for short in all the harness and components connected to EFI fuse.
