14. Connect the ABS/TCS control unit connector
A (26P) terminal No. 1 to body ground with a
jumper wire.
15. Turn the ignition switch ON (II).
Repair open in the wire between the ABS/
TCS control unit and body ground (G303).
Go to step 16.
16. Measure the voltage between the ABS/TCS control
unit connector A (26P) terminal No. 13 and body
ground.
Go to step 17.

1. Turn the ignition switch ON (II), and watch the TCS
indicator.
If the TCS indicator comes on and goes off, it’s
OK. If the TCS indicator stays on, go to step 7.
Go to step 2.
2. Turn the ignition switch OFF, then ON (II) again.
Go to step 3.
Repair open in the brake system indicator
circuit.
• Blown BACKUP LIGHT (7.5A) fuse.
• Open in the wire between the BACKUP LIGHT
(7.5A) fuse and the gauge assembly.
• Open circuit inside the fuse box.
3. Check the TCS indicator bulb in the gauge
assembly.
Go to step 4.
Replace the TCS indicator bulb.
4. Connect the gauge assembly connector B (22P)
terminal No. 13 and body ground with a jumper
wire.
Go to step 5.
Replace the printed circuit board in the gauge
assembly.
5. Remove the jumper wire at the gauge assembly,
and connect the ABS/TCS control unit connector
B (16P) terminal No. 16 and body ground with a
jumper wire.
Go to step 6.
Repair open in the wire between the gauge
assembly and the ABS/TCS control unit.
6. Connect the ABS/TCS control unit connector
C (12P) terminal No. 2 and body ground with a
jumper wire.
Repair open in the wire between the ABS/
TCS control unit and body ground (G101).
Check for loose ABS/TCS control unit
connectors. If necessary, substitute a known-good
ABS/TCS control unit, and recheck.

Brake System Indicator Circuit Troubleshooting
1. Release the parking brake.
2. Turn the ignition switch ON (II), and check the brake
system indicator for the following conditions:
• Brake system indicator does not come on at all,
go to step 3.
• Brake system indicator stays on all the time, go
to step 5.
• Brake system indicator comes on for 2 seconds,
then goes off. Repair open in the wire between
terminal No. 3 of the ALT 4P connector and
terminal B8 of the gauge assembly.
3. Turn the ignition switch OFF then ON (II) again.
Go to step 4.
Repair open in the indicator power source
circuit.
• Blown BACKUP LIGHT (10A) fuse.
• Open in the wire between the BACKUP LIGHT
(10A) fuse and the gauge assembly.
• Open circuit inside the fuse box.
4. Check the brake system indicator bulb in the gauge
assembly.
Repair open in the brake system indicator
circuit.
Replace the brake system indicator bulb.
5. Start the engine.
System is OK at this time.
Go to step 6.
6. Check the ABS indicator.
Read the ABS DTC’s (see page 19-82), and do
the applicable troubleshooting.
Go to step 7.
7. Turn the ignition switch OFF.
8. Disconnect the ABS/TCS control unit connector
B (16P).
9. Start the engine, and check the brake system
indicator.
Replace the ABS/TCS control unit.
Check the brake system indicator circuit
(short to body ground between terminal No. 3 of
the ALT 4P connector and terminal B8 of the gauge
assembly), parking brake switch (stuck ON) and
brake fluid level switch (stuck ON).
