Integration Relay -- On-Vehicle Inspection



1. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
ПРЕДОСТЕРЕЖЕНИЕ:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.


2. INSPECT INTEGRATION RELAY
ПРИМЕЧАНИЕ:
  1. The EFI relay is built into the integration relay (unit A: EFI MAIN).
  2. Some relays are built into the integration relay. The integration relay cannot be disassembled. If there is a malfunction in the circuit of the integration relay, replace the integration relay.

    1. Check the resistance of the EFI MAIN fuse.
      If the result is not as specified, replace the EFI MAIN fuse.

    2. Measure the resistance of the integration relay.

      Standard resistance:
      Tester Connection
      		Specified Condition
      1A-4 - 1C-1
      		10 kΩ or higher
      1A-4 - 1A-1
      1A-4 - 1C-1
      		Below 1 Ω (when battery voltage is applied to terminals 1A-3 and 1A-2)
      1A-4 - 1A-1
      If the result is not as specified, replace the integration relay.
