Fig. Fig. 1 Measure the resistance of the terminals on the circuit opening relay-Cressida

  1. Remove the left kick panel. This relay is located next to the number 1 junction block.
  2.  
  3. Using a voltmeter, check the voltmeter indicates voltage at the Fp terminal during engine cranking and running. Turn the engine OFF.
  4.  
  5. Disconnect the wiring.
  6.  
  7. Using a ohmmeter, measure the resistance between the terminal.
  8.  
  9. The resistance should be as follows:

    Between terminals STA and E1: 17-25 omega
     
    Between terminals +B and Fc: 88-112 omega
     
    Between terminals +B and Fp: infinity ( f )
     

  10.  
  11. If resistance is not as specified, replace the relay.
