2) Measure the ignition power voltage between
tire pressure monitoring control module con-
nector and chassis ground.
Connector & terminal
(R211) No. 5 (+) — Chassis ground (–):
Is the voltage 10 — 15 V? Go to step 11 . Repair open circuit
of the harness
between the tire

(R211) No. 9 — Chassis ground:
Is the resistance less than 0.5
:
? Go to step 12 . Repair open circuit
of the harness of
the tire pressure
monitoring control
module.
