Inspection Procedure

WARNING: This page is about a different car, the 2007 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.

CHECK OPERATION OF SPEEDOMETER
1. Drive the vehicle and check if the function of the speedometer on 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.
  - The speed indicated on the speedometer has an allowable margin of error. This can be tested using a speedometer tester (calibrated chassis dynamometer). For details about testing and the margin of error, refer to "ON-VEHICLE INSPECTION ".
NG: Go TO METER / GAUGE SYSTEM

OK: Go to next step
INSPECT NAVIGATION RECEIVER ASSEMBLY

1. Disconnect the navigation receiver assembly connector R5.
2. Measure the voltage.
  1. Jack up either one of the drive wheels.
  2. Move the shift lever to the neutral position.
  3. Turn the ignition switch to the ON position.
  4. Measure the voltage between terminal SPD of the navigation receiver assembly and body ground when the drive wheels are turned slowly.

Disconnect the navigation receiver assembly connector R5 and combination meter connector C7.

Measure the resistance according to the value(s) in the table below.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION CHART

Tester connection	Condition	Specified condition
SPD - +S	Ignition switch off	Below 1 Ω

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR

OK: Go to next step

CHECK HARNESS AND CONNECTOR (COMBINATION METER - NAVIGATION RECEIVER ASSEMBLY)

Fig 4: Checking Harness And Connector (Combination Meter - Navigation Receiver Assembly)

Disconnect the navigation receiver assembly connector R5 and combination meter connector C7.

Measure the resistance according to the value(s) in the table below.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION CHART

Tester connection	Condition	Specified condition
SPD - Body ground	Ignition switch off	10 kΩ or higher

HINT:

If the resistance between terminal SPD and body ground is less than 10 kΩ, there may be a short in a wire harness, connector, or an ECU.

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR OR EACH ECU

OK: REPLACE COMBINATION METER
