DESCRIPTION
If the ECU detects trouble, the tire pressure warning light blinks (comes on after blinking for 1 minute) and tire pressure monitor is cancelled at the same time. At this time, the ECU records a DTC in the memory.
Connect terminals TC and CG of DLC3 to make the tire pressure warning light blink and output the DTC.

INSPECTION PROCEDURE
NOTICE: When replacing the tire pressure warning ECU, read the transmitter IDs stored in the old ECU using the intelligent tester and write them down before removal.
It is necessary to perform initialization (See page TW-23) after registration (See page TW-20) of the transmitter IDs into the tire pressure warning ECU, after the ECU has been replaced.
HINT: This procedure must be performed according to the PROBLEM SYMPTOMS TABLE.
1 CHECK HARNESS AND CONNECTOR (COMBINATION METER - TIRE PRESSURE WARNING ECU)
(a) Disconnect the C10 combination meter connector.
(b) Disconnect the T15 tire pressure warning ECU connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance
2 INSPECT COMBINATION METER
(a) Disconnect the connector from the tire pressure warning ECU.
(b) Turn the ignition switch to the ON position, and check if the tire pressure warning light illuminates.
Result
REPLACE TIRE PRESSURE WARNING ECU (See page TW-87)
Throttle Actuator Control Motor Circuit
DESCRIPTION
The throttle actuator is operated by the ECM and opens and closes the
throttle valve using gears.
The opening angle of the throttle valve is detected by the Throttle Position
(TP) sensor, which is mounted
on the throttle body. The TP sensor provides feedback to the ECM. This ...

1. INSPECT POWER STEERING RACK
(a) Using a dial indicator, check the power steering rack
for runout and for teeth wear and damage.
Maximum runout:
0.3 mm (0.012 in.)
If necessary, replace the rack & pinion power
steering gear assembly.
(b) Check the back surface for wear and damag ...
