DTC 13
DIAGNOSIS:- Disconnection or short circuit of vehicle speed sensor 2 (MT model) or transmission control module (AT model).
TROUBLE SYMPTOM:
- Cruise control cannot be set. (Cancelled immediately.)
WIRING DIAGRAM:
8D1: CHECK TRANSMISSION TYPE.
CHECK: Is the transmission type MT?
YES: Go to step 8D2.
NO: Go to step 8D6.
8D2: CHECK HARNESS CONNECTOR BETWEEN CRUISE CONTROL MODULE AND VEHICLE SPEED SENSOR 2.
1. Disconnect connector from vehicle speed sensor 2 and cruise control module.
Connector & terminal (B17) No.1 - (B94) No.18:
2. Measure resistance of harness connector between vehicle speed sensor 2 and cruise control module.
CHECK: Is the resistance less than 10 ohm?
YES: Go to step 8D3.
NO: Repair wiring harness.
8D3: CHECK HARNESS CONNECTOR BETWEEN BATTERY AND VEHICLE SPEED SENSOR 2.
1. Turn ignition switch to ON.
Connector & terminal (B17) No.3 (+) - Chassis ground (-):
2. Measure voltage between vehicle speed sensor 2 connector (B17) and chassis ground.
CHECK: Is the voltage more than 10 V?
YES: Go to step 8D4.
NO: Repair harness connector between battery and vehicle speed sensor 2.
8D4: CHECK HARNESS CONNECTOR BETWEEN VEHICLE SPEED SENSOR 2 AND ENGINE GROUND.
1. Turn ignition switch to OFF.
Connector & terminal (B17) No.2 (+) - Engine ground (-):
2. Measure resistance between vehicle speed sensor 2 connector (B17) and engine ground.
CHECK: Is the resistance less than 10 ohms?
YES: Go to step 8D5.
NO: Repair harness connector between vehicle speed sensor 2 and engine ground.
8D5: CHECK VEHICLE SPEED SENSOR 2.
1. Connect connector to vehicle speed sensor 2.
2. Set the vehicle on free roller, or lift-up the vehicle and support with safety stands.
WARNING: Be careful not to be caught up by the running wheels.
3. Set oscilloscope to vehicle speed sensor 2 connector terminals.
Positive probe; (B17) No.1
Earth lead; (B17) No.2
4. Drive the vehicle at speed greater than 20 kph (12 MPH).
5. Measure signal voltage indicated on oscilloscope.
CHECK: Is the voltage more than 5 V?
YES: Replace cruise control module.
NO: Replace vehicle speed sensor 2.
8D6: CHECK HARNESS CONNECTOR BETWEEN CRUISE CONTROL MODULE AND AUTOMATIC TRANSMISSION CONTROL MODULE
1. Disconnect connector from automatic transmission control module and cruise control module.
Connector & terminal (B94) No.18 - (B55) No.13:
2. Measure resistance between cruise control module connector and automatic transmission control module connector.
CAUTION: To measure the voltage and/or resistance, use a tapered pin with a diameter of less than 0.64 mm (0.025 in). Do not insert the pin more than 5 mm (0.20 in).
CHECK: Is the resistance less than 10 ohms?
YES: Go to step 8D7.
NO: Repair harness connector between cruise control module and automatic transmission control module.
8D7: CHECK AUTOMATIC TRANSMISSION CONTROL MODULE.
1. Connect connector to automatic transmission control module.
2. Set the vehicle on free roller, or lift-up the vehicle and support with safety stands.
WARNING: Be careful not to be caught by the running wheels.
3. Drive the vehicle faster than 10 kph (6 MPH).
Connector & terminal (B55) No.13 (+) - Chassis ground (-):
4. Measure voltage between automatic transmission control module connector (B55) and chassis ground.
CAUTION: To measure the voltage and/or resistance, use a tapered pin with a diameter of less than 0.64 mm (0.025 in). Do not insert the pin more than 5 mm (0.20 in).
CHECK: Is the voltage less than 1 V <--> more than 4 V?
YES: Replace cruise control module.
NO: Replace automatic transmission control module.
