14. Disconnect the modulator unit connector, and

remove the jumper wire from the TCS relay
connector terminal.

15. Check for continuity between the modulator unit

connector terminal No. 17 and the TCS relay
terminal No. 2.

Replace the modulator unit.

Repair open in the wire between the

modulator unit and the TCS relay.

16. Disconnect the modulator unit connector, and

remove the jumper wire from the TCS relay
connector terminal.

17. Check for continuity between the appropriate ABS/

TCS control unit connector A (26P) terminal and all
other ABS and TCS solenoid circuit terminals (see
table).

Replace the modulator unit.

Check for loose ABS/TCS control unit

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

1. Check the TCS (10A) fuse in the passenger’s under-

dash fuse/relay box, and reinstall the fuse if it is OK.

Go to step 2.

Replace the fuse, and recheck.

2. Turn the ignition switch ON (II).

Repair short to body ground in the wire

between the TCS relay and modulator unit.

Go to step 3.

3. Check the TCS relay in the under-hood multi-fuse/

relay box (see page 22-88). The wire colors of the
TCS relay connector are BLU/BLK, RED/BLU, BRN/
BLK, and GRN/YEL.

Do not reinstall the TCS relay, and go to step

Replace the TCS relay.

4. Measure the voltage between the TCS relay

connector terminal No. 1 and body ground.

Go to step 5.

Repair open in the wire between the under-

hood fuse/relay box and the TCS relay.

6. Disconnect the modulator unit connector.

7. Measure the voltage between terminal No. 17 and

body ground.

Go to step 8.

Repair open in the wire between the TCS

relay and the modulator unit.

8. Remove the jumper wire from the TCS relay

connector.

9. Measure the voltage between the modulator unit

connector terminal No. 17 and body ground.

Repair short to power in the wire between

the TCS relay and the modulator unit.

Go to step 10.

10. Disconnect the ABS/TCS control unit connector B

(16P).

11. Turn the ignition switch ON (II).

12. Measure the voltage between terminal No. 13 and
