ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT SPEEDOMETER

NOTICE:

  • The combination meter assembly receives the vehicle speed signal from the skid control ECU (brake actuator assembly) via CAN communication. Therefore, perform the following inspection referring to values on the Data List of the skid control ECU (brake actuator assembly) because it is the source of the vehicle speed signal.
  • Data List values of the skid control ECU (brake actuator assembly) are used for this inspection. Therefore, make sure to perform this inspection after confirming that DTCs are not output.
  • If the tire size or tire inflation pressure is not within the specified range, or the tires are excessively worn, the speedometer indication error will increase. Therefore, make sure to perform this inspection after checking that the tire size, tire inflation pressure and tire wear are in the specified range.

(a) Warm up the engine.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch to ON.

(d) Turn the Techstream on.

(e) Enter the following menus: Chassis / Brake / Data List.

(f) Read the Data List according to the display on the Techstream.

2. INSPECT TACHOMETER

(a) Warm up the engine.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch to ON.

(d) Turn the Techstream on.

(e) Enter the following menus:

  • Powertrain / Engine / Data List. (for M20A-FKS)
  • Powertrain / Engine and ECT / Data List. (for 2ZR-FAE)
