2ZR-FE ENGINE CONTROL SYSTEM: INTEGRATION RELAY: INSPECTION

INSPECTION

1. INSPECT INTEGRATION RELAY





(a) Inspect the EFI fuse.
(1) Disconnect the fuse.
(2) Using an ohmmeter, measure the resistance of the fuse.
Standard resistance:






(b) Inspect the EFI relay.
(1) Measure the resistance according to the value(s) in the table below.
Standard resistance:





NOTE: While using the battery for the inspection, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.





(c) Inspect the cooling fan relay.
(1) Measure the resistance according to the value(s) in the table below.
Standard resistance:





NOTE: While using the battery for the inspection, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.





(d) Inspect the IG2 relay.
(1) Measure the resistance according to the value(s) in the table below.
Standard resistance:
