Main Relay (Computer/Fuel System): Testing and Inspection
Control Relay Location
Control Relay Operation
To test the Control Relay, located in the passenger compartment (under dash, passenger side), Proceed as follows.
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 could interrupt power supply to the fuel pump, injectors and ECU, resulting in start failure.
NOTE: Confirm circuit tester polarity before checking continuity.
1.
In the following order check continuity between the specified terminals, as instructed.
To test coils L1 and L2:
Check terminals 1 and 7: should be non-conductive (infinite ohm).
Check terminals 2 and 5: should be conductive (Approx. 95 ohm).
Check terminals 2 and 3: should be conductive (Approx. 95 ohm).
Check terminals 6 and 4: should be conductive (Approx. 35 ohm).
