Integration Relay -- On-Vehicle Inspection |
| 1. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL |
| 2. INSPECT INTEGRATION RELAY |
- NOTICE:
- The EFI relay is built into the integration relay (unit A: EFI MAIN).
- 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.
Using a screwdriver, detach the 2 claws and disconnect the integration relay from the engine room No. 1 junction block.
- HINT:
- Tape the screwdriver tip before use.
 |
Disconnect the 3 connectors from the integration relay.
Inspect the EFI MAIN relay.
Check the resistance of the EFI MAIN fuse.
If the result is not as specified, replace the EFI MAIN fuse.Measure the resistance of the integration relay.
- Standard resistance:
Tester Connection Specified Condition 1C-1 - 1A-4 10 kΩ or higher 1C-1 - 1A-4 Below 1 Ω (when battery voltage is applied to terminals 1A-2 and 1A-3)
Inspect the A/F relay.
Check the resistance of the A/F fuse.
If the result is not as specified, replace the A/F fuse.Measure the resistance of the integration relay.
- Standard resistance:
Tester Connection Specified Condition 1C-1 - 1B-8 10 kΩ or higher 1C-1 - 1B-8 Below 1 Ω (when battery voltage is applied to terminals 1B-6 and 1B-7)
