• This code is caused by an electrical circuit problem
and cannot be caused by a mechanical problem in the
transmission.
1. Turn the ignition switch ON (II).
2. Shift to all positions other than R.
3. Measure the voltage between PCM connector
terminals D6 and B20 or B22 .
PCM CONNECTORS
B (25P)
LG2 (BRN/YEL)
LG1 (BRN/YEL)
Wire side of female terminals
Is there battery voltage?
YES Go to step 4.
NO Check for a short in the wire between PCM
connector terminal D6 and the transmission range
switch or A/T gear position indicator, and check for
an open in the wires between PCM connector
terminals B20 and B22 and body ground (G101). If
the wires are OK, check for loose terminal fit in the
PCM connectors. If necessary, substitute a known-
good PCM and recheck.
D (16P)
ATP R (WHT)
4. Shift to all positions other than P or N.
5. Measure the voltage between PCM connector
terminals B14 and B20 or B22 .
PCM CONNECTOR B (25P)
LG2 (BRN/YEL)
LG1 (BRN/YEL)
Wire side of female terminals
Is there about 5 V ?
YES Go to step 6.
NO Check for a short in the wire between PCM
connector terminal B14 terminal and the
transmission range switch. If the wires are OK,
check for loose terminal fit in the PCM connectors.
If necessary, substitute a known-good PCM and
recheck.
