Was “A / T DIAGNOSTIC FLOW TABLE” in this
section performed?
Go to Step 2.
Go to “A / T
DIAGNOSTIC FLOW
TABLE” in this section.

Check acceleration stroke signal input circuit for
open.
1) Turn ignition switch OFF and disconnect TCM
and ECM connectors.
2) Check for proper connection to TCM and
ECM at following terminals.
For vehicle equipped with single-connector
ECM: E202-6 and C51-64.
For vehicle equipped with triple-connector
ECM: E202-6 and E229-28.
3) If OK, measure resistance between terminal
E202-6 of disconnected harnesses side TCM
connector and following terminal.
For vehicle equipped with single-connector
ECM : terminal C51-64 of disconnected
harness side ECM connector.
For vehicle equipped with triple-connector
ECM: terminal E229-28 of disconnected
harness side ECM connector.
Is it about 0
Ω
?
Go to Step 3.
“BLU / WHT” circuit
open.
3
Check acceleration stroke signal input circuit for
short.
Measure between terminal E202-6 of
disconnected harness side TCM connector and
ground.
Is it infinity?
Go to Step 4.
“BLU / WHT” circuit
shorted to ground.
4
Check acceleration stroke signal input circuit for
short to power circuit.
1) With ignition switch OFF, connect ECM
connector.
2) Turn ignition switch ON.
3) Measure voltage between terminal E202-6 of
disconnected harness side TCM connector and
ground.
Is it about 0 V?
Go to Step 5.
“BLU / WHT” circuit
shorted to power
circuit.
5
Check TCM terminal voltage.
1) With ignition switch OFF, connect TCM
connector and disconnect ECM connector.
2) Turn ignition switch ON.
3) Measure voltage between following terminal
and ground.
For vehicle equipped with single-connector
ECM: terminal C51-64 of disconnected harness
side ECM connector.
For vehicle equipped with triple-connector
ECM: terminal E229-28 of disconnected
harness side ECM connector.
Is it 10 – 14 V?
Intermittent trouble,
faulty TCM or faulty
ECM.
Check for intermittent
referring to
“INTERMITTENT AND
POOR CONNECTION”
in Section 0A.
If OK, substitute a
known-good TCM or
ECM and recheck.
Substitute a known-
good TCM and
recheck.
