Pinout Values and Diagnostic Parameters
CHECK AT ABS-ECUUse the following steps to remove the connector cover of the ABS-ECU and then measure the terminal voltage.
1. Move the lock lever of the ABS-ECU connector as shown in the illustration, and then disconnect the ABS-ECU as connector.
2. Push up and unlock the hooks of the ABS-ECU connector as shown in the illustration, then remove the connector cover.
TERMINAL VOLTAGE CHECK CHART
1. Measure the voltages between terminals (12) (ground terminal) and each respective terminal.
2. The terminal layout is shown in the illustration.
NOTE: Do not measure terminal voltage for approximately three seconds after ignition switch is turned ON. The ABS-ECU performs the initial check during that period.
RESISTANCE AND CONTINUITY BETWEEN HARNESS-SIDE CONNECTOR TERMINALS
1. Turn the ignition switch to the LOCK (OFF) position and disconnect the ABS-ECU connectors before checking resistance and continuity.
2. Check the resistance and continuity between the terminals indicated in the table.
3. The terminal layout is shown in the illustration.
