Alternator Control System Test (KU, KT, KX, KK models) Check for proper operation of the ELD by checking the MIL 4-door (see page 11-3) or 5-door (see page 11-309). Disconnect the alternator 4P connector from the alternator. Start the engine, and turn the headlights (high beam) ON. Measure voltage between the alternator 4P connector terminal No. 2 and the positive terminal of the battery. BATTERY ALTERNATOR 4P CONNECTOR Wire side of female terminals Is there 1 V or less? YES - Go to step 8. NO - Go to step 5. Turn the headlight and ignition switch OFF. Disconnect ECM/PCM connector B (24P).

Check for continuity between ECM/PCM connector terminal B18 and body ground. ECM/PCM CONNECTOR B (24P) Wire side of female terminals Is there continuity? YES - Repair short in the wire between the alternator and ECM/PCM. NO - Substitute a known-good ECM/PCM, and recheck (see page 11-3) or 5-door (see page 11-309). If prescribed voltage is now available, replace the original ECM/PCM. Turn the headlight and ignition switch OFF. Disconnect ECM/PCM connector B (24P). Check for continuity between ECM/PCM connector terminal B18 and alternator 4P connector terminal No. 2. ECM/PCM CONNECTOR B (24P) ALTERNATOR 4P CONNECTOR Wire side of female terminals Is there continuity? YES - Repair the alternator (see page 4-32). NO - Repair open in the wire between the alternator and ECM/PCM.
