Main Relay (Computer/Fuel System): Testing and Inspection

Control Relay

CAUTION: When applying battery voltage directly. make sure that it is applied to the correct terminal. Otherwise. the relay could be damaged.

NOTE: Failure of the control relay interrupts power supply to the fuel pump. injectors and ECU. resulting in start failure.

1. Check continuity between the terminals when the relay coil is energized and when it is not.

NOTE: In the following tables. the arrows indicate the direction of the current flow.

Confirm circuit tester polarity before checking continuity.











NOTE: Energized' means voltage applied across terminals 6 and 7.











NOTE:
"Energized" means voltage applied across terminals 5 and 7

2. If the result is not satisfactory, replace the control relay.
