CAUTION:
Remove foreign matter (dust, water, oil etc.) from the tire pressure monitoring control module con-
nector when removing or installing.
NOTE:
To check harness for broken wires or short circuits, shake trouble spot or connector.
Step Check Yes No
1CHECK PRE-INSPECTION.
1) Check with the user regarding when the
warning light lit or started blinking.
2) Before performing diagnostics, check the
components which might mal-affect tire pres-
sure monitor system.
Is the component that might
affect the tire pressure monitor
system normal?
Go to step 2.Repair or replace
each component.
