On-Vehicle Inspection [09/2015 - ]: Procedure

HINT: 

The ABS motor relay (ABS MTR1) cannot be removed and inspected, as it is an internal relay of the engine room junction block.

1. Turn the power switch OFF.
2. Connect the Techstream to the DLC3.
3. Remove the relay inspection terminal cover of the engine room No. 2 junction block.

   *2	Engine Room No. 2 Junction Block

4. Turn the power switch ON (IG).
5. Using the Techstream, perform the Active Test for the ABS motor relay (ABS MTR1) and measure the voltage between the relay inspection terminals of the engine room junction block.

   HINT: 

   As the ABS motor relay (ABS MTR1) is a semiconductor relay, there are no operation sounds.

   If the result is not as specified, check the harness and connector and replace them as necessary.

   If the harness and connector are in good condition, replace the engine room No. 2 junction block assembly.

1. Remove the ABS motor relay from the No. 3 relay block.
2. Measure the resistance according to the value(s) in the table below.

   Standard resistance

   Tester Connection	Condition	Specified Condition
   3 - 5	When battery voltage is not applied to terminals 1 and 2	10 kΩ or higher
   3 - 5	When battery voltage is applied to terminals 1 and 2	Below 1 Ω

   If the result is not as specified, replace the relay.

3. Install the ABS motor relay.
