Toyota RAV4 Service Manual: Open in stop light switch circuit

Description

The skid control ecu detects the brake operating conditions through a signal transmitted by the stop light switch. The skid control ecu incorporates an open circuit detection circuit. This dtc is set under either of the following conditions:

  1. Disconnect the a19 ecu connector.
  2. Measure the voltage of the wire harness side connector.

Standard voltage




Replace abs and traction actuator assembly

  1. Inspect fuse (stop, ecu-ig1)

  1. Remove the stop fuse and ecu-ig1 fuse from the instrument panel junction block.
  2. Measure the resistance of the fuse.

Standard resistance: below 1




  1. Inspect stop light control relay (marking: brk)
