When disconnecting the fuel injector connector, the malfunction indicator light illuminates and DTC is stored in ECM memory.
Therefore, carry out the clear memory mode and inspection
mode after connecting the fuel injector connector.

3. General Description
A: CAUTION
•SRS AIRBAG SYSTEM
The airbag system wiring harness is routed near
the TCM.
CAUTION:
•All air bag system wiring harnesses and con-
nectors are colored yellow. Do not use an elec-
tric test equipment to check these circuits.
•Be careful not to damage the airbag system
wiring harness when performing diagnostics or
servicing the TCM.
•MEASUREMENT
When measuring the voltage and resistance of the
ECM, TCM or each sensor, use a tapered pin with
a diameter of less than 0.64 mm (0.025 in) in order
to avoid poor contact. Do not insert a pin of more
than 0.65 mm (0.026 in) diameter.
