6. With an analog voltmeter set to the 10 V or similar

range, measure the voltage between the PCM
connector D (17P) terminal No. 11 and body ground.

Go to step 7.

Check for loose PCM connectors. If necessary,

substitute a known-good PCM, and recheck.

7. With an analog voltmeter set to the 10 V or similar

range, measure the voltage between the ABS/TCS
control unit connector B (16P) terminal No. 7 and
body ground.

Check for loose ABS/TCS control unit

connectors. If necessary, substitute a known-good
ABS/TCS control unit, and recheck.

Repair open in the wire between the PCM and

the ABS/TCS control unit.

NOTE: If the MIL or ABS indicator is ON, troubleshoot
the PGM-FI or ABS first.

1. Disconnect the PCM connector E (20P) and the

ABS/TCS control unit connector B (16P).

2. Check for continuity between the PCM connector E

(20P) terminal No. 7 and body ground.

Repair short to body ground in the wire

between the PCM and the ABS/TCS control unit.

Go to step 3.

3. Connect the PCM connector E (20P).

4. Start the engine.

NOTE: Use the 10 V range or similar range in an
analog tester.

Go to step 6.

Check for loose PCM connectors. If necessary,

substitute a known-good PCM, and recheck.

6. With an analog voltmeter set to the 10 V or similar

range, measure the voltage between the ABS/TCS
control unit connector B (16P) terminal No. 10 and
body ground.

Check for loose ABS/TCS control unit

connectors. If necessary, substitute a known-good
ABS/TCS control unit, and recheck.

Repair open in the wire between the PCM and

NOTE: If the MIL or ABS indicator is ON, troubleshoot
the PGM-FI or ABS first.

1. Disconnect the PCM connector A (32P), the

ABS/TCS control unit connector B (16P), and the
gauge assembly connector A (30P).

2. Check for continuity between the PCM connector A

(32P) terminal No. 19 and body ground.

Repair short to body ground in the wire

between the PCM and the ABS/TCS control unit.

Go to step 3.

3. Connect the PCM connector A (32P).

4. Start the engine, warm it up to normal operating

temperature, and let it idle.

5. With an analog voltmeter set to the 10 V or similar

range, measure the voltage between the PCM
connector A (32P) terminal No. 19 and body ground.

Go to step 6.

Check for loose PCM connectors. If necessary,

substitute a known-good PCM, and recheck.

6. With the engine still idling, measure the voltage

between the ABS/TCS control unit connector
B (16P) terminal No. 11 and body ground with the
analog voltmeter again.

The system is OK at this time. If the problem

recurs, replace the ABS/TCS control unit.

Repair open in the wire between the PCM and

ABS/TCS control unit.

NOTE: If the MIL or ABS indicator is ON, troubleshoot
the PGM-FI or ABS first.

1. Disconnect the PCM connector E (20P) and the

ABS/TCS control unit connector B (16P).

2. Check for continuity between the PCM connector

E (20P) terminal No. 6 and body ground.

Repair short to body ground in the wire

between the PCM and the ABS/TCS control unit.

Go to step 3.

3. Connect the PCM connector E (20P).

4. Turn the ignition switch ON (II).
