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.

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
