Inspection Procedure

WARNING: This page is about a different car, the 2004 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

Measure resistance between terminals CANL and CANH of DLC3.

CHECK:

Measure the resistance between terminals CANL and CANH of the DLC3.

RESULT:

RESISTANCE MEASURING

Result	Proceed to
54 to 66 Ω	A
1 MΩ or higher	B

A : Go to step 3 .
B : Go to next step.

Check for short circuit in harness and connector between junction connector and DLC3.
PREPARATION:

Disconnect the bus line connectors from the junction connector.

CHECK:

Measure the resistance between terminals CANL and CANH of the DLC3.

OK:

Resistance: 1M Ω or higher
1. NG : Repair or replace harness and connector between junction connector and DLC3 and go to step 3 .
2. OK : Go to next step.
Check for short circuit in harness and connector between terminals CANL and CANH of the yaw rate sensor wire harness side connector.
PREPARATION:
1. Disconnect the bus line connectors form the junction connector.
2. Disconnect the yaw rate sensor connector.
CHECK:

Measure the resistance between terminals CANL and CANH of the yaw rate sensor wire harness side connector.

OK:

Resistance: 54 to 66 Ω
1. NG : Repair or replace harness and connector between junction connector and yaw rate sensor.
2. OK : Go to next step.
Measure voltage of IG power source.
PREPARATION:

Disconnect the yaw rate sensor connector.

CHECK:
1. Turn the ignition switch ON.
2. Measure the voltage between terminals IG and GND of the yaw rate sensor connector.
OK:

Voltage: 10 to 14 V
1. NG : Go to step 5 .
2. OK : Replace yaw rate sensor.
NOTE: When replacing the yaw rate sensor, perform the zero point calibration (see PRE-CHECK ).
Measure resistance between terminal GND of yaw rate sensor connector and body ground.
PREPARATION:

Disconnect the yaw rate sensor connector.

CHECK:

Measure the resistance between terminal GND of the yaw rate sensor harness side connector and body ground.
