(b) Disconnect the cable from the negative (-) battery terminal.
NOTICE:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
(c) Interchange the rear airbag sensor RH with LH and connect the connectors to them.
(d) Connect the cable to the negative (-) battery terminal.
(e) Turn the engine switch on (IG), and wait for at least 60 seconds.
(f) Clear the DTCs stored in the the memory See: Restraints and Safety Systems/Air Bag Systems/Testing and Inspection/Reading and
Clearing Diagnostic Trouble Codes/DTC Check / Clear.
(g) Turn the engine switch off.
(h) Turn the engine switch on (IG), and wait for at least 60 seconds.
(i) Check for DTCs See: Restraints and Safety Systems/Air Bag Systems/Testing and Inspection/Reading and Clearing Diagnostic

TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: C2121/21-C2125/25,C2181/81-C2185/85: No Signal from
Transmitter ID1
C2185/85 - Transmitter ID5 not Received (Test Mode DTC)
DESCRIPTION
The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the tire pressures. The measured values
are transmitted to the tire pressure warning antenna and receiver on the body as radio waves and then sent to the tire pressure warning ECU. The
ECU compares the measured air pressure values with the air pressure threshold. When the measured air pressure value is less than this threshold, the
warning light in the combination meter turns on.
The tire pressure warning valve and transmitters constantly send radio waves to the tire pressure warning antenna and receiver.
Under the conditions below, the tire pressure warning antenna and receiver may be unable to receive the signals from the tire pressure warning valve
and transmitters, causing a DTC to be stored.
