DTC 21 Vehicle Speed Sensor Circuit
CIRCUIT DESCRIPTION
The vehicle speed sensor signal is sent to the cruise control ECU as the vehicle speed signal.
The rotor shaft in driven by the gear of the transaxle.
For each rotation of the shaft, the speed sensor sends a 4−pulse signal to the combination meter.
This signal is converted inside the combination meter and sent as a 4−pulse signal to the cruise control ECU.
The ECU calculates the vehicle speed from this pulse frequency.

Electronically Controlled Transaxle Communication Circuit
CIRCUIT DESCRIPTION
When driving uphill under cruise control, in order to reduce shifting due to ON−OFF overdrive operation and
to provide smooth driving, when down shifting in the electronically controlled transaxle occurs, a signal to
prevent upshift until the end of the uphill slope is sent from the cruise control ECU to the electronically con-
trolled transaxle.
Terminal ECM of the cruise control ECU detects the shift change signal (output to electronically controlled
transaxle No.2 solenoid) from the electronically controlled transaxle.
If vehicle speed down, also when terminal electronically controlled transaxle of the cruise control ECU re-
ceive down shifting signal, it sends a signal from terminal OD to OD1 to cut overdrive until the end of the
uphill slope, and the gear shifts are reduced and gear shift points in the electronically controlled transaxle
are changed.

INSPECTION PROCEDURE
1 Check operation of overdrive.
PREPARATION:
Test drive after engine warm up.
CHECK:
Check that overdrive ON ↔ OFF occurs with operation of OD switch ON − OFF.
NG Check and repair electronically controlled
transaxle (See page DI−141 or DI−192).
OK
2 Check voltage between terminal OD of harness side connector of ECU and body
ground.
PREPARATION:
Remove ECU with connector still connected.
CHECK:
(a) Disconnect ECU connector.
(b) Turn ignition switch ON.
(c) Measure voltage between terminal OD of harness side
connector of ECU and body ground.
OK:
Voltage: 10 − 16 V
NG Go to step 5.
OK
