|10.||Check for continuity between ABS modulator-control unit 25P connector terminal and ECM/PCM connector A (44P) terminal (see table).|
Is there continuity?
YES - Check for loose terminals in the ECM/PCM connector A (44P) and at the ABS modulator-control unit 25P connector. If necessary, substitute a known-good ECM/PCM, then go to step 1 and recheck. If no DTCs are indicated, replace the original ECM/PCM: R18A1 engine model, K20Z2 engine model. If DTCs are indicated, replace the ABS modulator-control unit: Except K20Z2 engine model, K20Z2 engine model.n
NO - Repair open in the wire between the ECM/PCM and the ABS modulator-control unit.n
