Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

2. INSPECT TIRE PRESSURE WARNING ANTENNA

(a) Disconnect the tire pressure warning antenna A59 and Q29 connectors.





(b) Check for continuity between the terminals of the antenna cable core and the shield wire.

HINT
Coaxial cable is used for the antenna.

OK:

Approx. 2 kOhms

NG -- REPLACE TIRE PRESSURE WARNING ANTENNA Removal
