Anti-Lock Brake System Circuit Check

1. Remove glove box or ECU cover, as required, and pull out ABS computer.
2. Using a multimeter with high impedance (10,000 ohms minimum), measure voltage and resistance at each terminal shown in Figs. 173 through 197, and body ground.
3. Ensure results are as shown.
