HINT:

A voltage of 12 V or 5 V is output from each ECU and then input to the combination meter. The signal is changed to a pulse signal at the transistor in the combination meter. Each ECU controls the respective system based on the pulse signal.
If a short occurs in an ECU, all systems in the diagram below will not operate normally.

CHECK OPERATION OF SPEEDOMETER
1. Drive the vehicle and check if the function of the speedometer in the combination meter is normal.
  OK: Actual vehicle speed and the speed indicated on the speedometer are the same.
  
  HINT:
  
  The vehicle speed sensor is functioning normally when the indication on the speedometer is normal.
NG : GO TO COMBINATION METER SYSTEM

OK : GO TO NEXT STEP
CHECK DTC OUTPUT (PUSH-BUTTON FUNCTION)
1. Delete the DTC (See DIAGNOSIS SYSTEM ).
  HINT:
  
  After all DTCs are cleared, check if the trouble occurs again 320 seconds after the engine switch is turned on (IG).
2. Check for DTCs again.
  OK: No DTC is output.
OK : CHECK INTERMITTENT PROBLEMS

NG : GO TO NEXT STEP
CHECK DTC OUTPUT (BRAKE SYSTEM)
1. Delete the DTC (See DIAGNOSIS SYSTEM ).
2. Check for the brake system DTCs C0200/31, C0205/32, C0210/33, C0215/34, C1235/35, C1236/36, C1238/38 and C1239/39.
  HINT:
  
  If the DTCs for the brake system or the vehicle speed sensor malfunction are output, inspect those DTCs first.
  
  With VDIM (See DTC CHECK / CLEAR ) Without VDIM (See DTC CHECK / CLEAR )
  
  OK: No DTC is output.
NG : GO TO BRAKE SYSTEM

OK : GO TO NEXT STEP
CHECK DTC OUTPUT (MULTIPLEX NETWORK COMMUNICATION SYSTEM (BEAN))
1. Delete the DTC (See DIAGNOSIS SYSTEM ).
2. Check for the multiplex network communication system DTCs B1210, B1214 and B1215.
  HINT:
  
  If the DTCs for the multiplex network communication system malfunction are output, inspect those DTCs first (See DTC CHECK/CLEAR ).
  
  OK: No DTC is output.
NG : GO TO MULTIPLEX COMMUNICATION SYSTEM

OK : GO TO NEXT STEP

READ VALUE OF INTELLIGENT TESTER (VEHICLE SPEED SIGNAL)

Connect the intelligent tester (with CAN VIM) to the DLC3.
Turn the engine switch on (IG).
Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST.

Check the DATA LIST for proper functioning of the vehicle speed signal.

Power source control ECU:

DATA LIST

Item	Measurement Item/Display (Range)	Normal Condition	Diagnostic Note
VEHICLE SPD SIG	Vehicle speed signal/ STOP or RUN	STOP: Vehicle is stopped RUN: Vehicle is running	-

OK: STOP (vehicle is stopped) and RUN (vehicle is running) appear on the screen.

NG : Go to step 6

OK : REPLACE POWER SOURCE CONTROL ECU

CHECK WIRE HARNESS (POWER SOURCE CONTROL ECU - COMBINATION METER)

Disconnect the J55 ECU connector.
Disconnect the J34 meter connector.

Measure the resistance of the wire harness side connectors.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION CHART

Tester Connection	Specified Condition
J55-19 (SPD) - J34-5 (+S)	Below 1 Ω
J55-19 (SPD) or J34-5 (+S) - Body ground	10 kΩ or higher
