Toyota Corolla Repair Manual: Inspection procedure

Hint

: start the inspection from step 1 in case of using the handheld tester and start from step 2 in case of not using the handheld tester.

1 Perform active test by handheld tester(abs motor relay)

  1. Check the operation sound of the abs motor individually when operaing it with the handheld tester.

    Ok: the operation sound of the abs motor should be heard.

2 Inspect skid control ecu connector(+bm terminal voltage)

2 Inspect skid control ecu connector(+bm terminal voltage)

  1. Disconnect the skid control ecu connector.
  2.  measure the voltage between terminals +bm (24) and gnd (1, 23) of skid control ecu harness side connector.

    Voltage: 10 14 v

3 Inspect fuse(abs no.2 Fuse)

3 Inspect fuse(abs no.2 Fuse)

  1. Remove abs no.2 Fuse from the engine room r/b.
  2. check continuity of abs no.2 Fuse.

    Ok: continuity

4 Inspect skid control ecu connector(gnd terminal continuity)

4 Inspect skid control ecu connector(gnd terminal continuity)

  1. Measure resistance between terminal gnd (1,23) of skid control ecu harness side connector and body ground.

    Resistance: 1 Ω or less

Circuit description
While driving uphill with cruise control activated, in order to minimize gear shifting and provide smooth cruising overdrive may be prohibited temporarily under some conditions. The cruise control ecu sends o/d cut signals to the ecm as necessary and the ecm cancels overdrive shifting until ...

Inspection procedure
1 Check side squib(rh) circuit(airbag sensor assy center front seat airbag assy rh) Disconnect the negative () terminal cable from the battery, and wait at least for 90 seconds.  disconnect the connectors between the airbag sensor assy center and the front seat airbag assy (rh ...

Wiring diagram
1 Inspect terminal voltage(pi) (a) turn Turn the ignition switch to on.  measure voltage between terminal 5 (pi) of cruise control ecu assy and body ground, when the cruise control main switch button is on and off. Ok: 2 Inspect combination meter assy 3 Check harn ...
