Specification: Below 1.0 Ω
Is the measured resistance within specification?
YES
- Go to "Check short to battery in harness" as follows.
NO
- Repair or replace as necessary and then, go to "VERIFICATION OF VEHICLE REPAIR " procedure

■ Check short to battery in harness

IG "OFF" and disconnect battery sensor and ECM connector.
IG "ON"
Measure the voltage between LIN terminal of battery sensor harness connector and chassis ground.
Specification: Approx. 0 V
Is the measured voltage within specification?
YES
- Go to "Check short to ground in harness" as follows.
NO
- Repair or replace as necessary and then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
