CHECK ECU VOLTAGE
1. Raise and support vehicle with safety stands.
CAUTION: On 4WD models, ensure that all four wheels are off the ground.
2. While driving wheels are slowly turning, measure voltage between ECU connector terminal (B58)11 and ground. It should oscillate between 0V
and 5V.
CHECK HARNESS BETWEEN ECU AND SPEED SENSOR
1. Disconnect ECU and combination meter connectors.
2. Measure resistance between ECU and combination meter connectors and ground as follows:
Connector & terminal:
Resistance:
(B58)11-(i16)11
0 Ohms
(i16)11-Ground
1M Ohms min.
(i16)7-Ground
0 Ohms
