ls there battery voltage?
Measure Powet SUPPIY Ci.cuit
Voltage:1. Turnthe ignition switch ON (ll)
2. Measure the voltage between
terminals A12 and A13 and
between terminals A25 and
426.
Repair open or short in the wire
between the A'12 andlor Ms ler-
minrls and the under-dash fuse
DOX,
Measure D IND Voltage:1. Turn the ignition switch OFF
2. connect the A (26P) connec
tor to the TcM.
3. Connect a digkal multitester
to the A20 and A'13 or A26 ter
minals.4. Turn the ignition switch ON (ll),
and make sure that the voltage
is available for two seconds.
Check tor opon in the wire
between the A20 l6rminal and
the gaug€ assembly. It the wite
is OK, check tor a faultY ipl indi-
calor light bulb or a faulty gauge
assembly prir ed circuit boatd.
Check D INO for an Shott Circuit:1. Turn the ignition switch OFF
2. Disconnect the A (26P) con-
nector from the TCM.
3. Check for continuity between
the A20 terminal and the No. I
terminal of the gauge assem-bly connector (see section 23).
Bepair open in the wire between
the A20 terminal and the gauge
assembly.
Check tor looso TCM connecto.s.
Check the A/T ge.r Positionswitch. lf nec6ssary, substitute a
known-good TCM and r€check
