ELECTRICAL POWER STEERING (P/S) SYSTEM 3B1-11
DIAGNOSTIC FLOW TABLE
Table A:
STEP ACTION YES NO
1 Are “IG·METER” and “EPS” fuses in good condition? Go to STEP 2. Check short to ground
in “B/W” (for “IG ME-
TER” fuse), “B/R” (for
“EPS” fuse) wire, and
then replace fuse.
2 1) Remove steering column lower cover.
2) Disconnect 8-pin (“A”) connector from P/S control
module.
3) Check proper connection to P/S control module at
terminal “A2”.
4) If OK, check voltage between “A2” and body ground.
5) Is it 10 – 14 V?
Go to STEP 3. Repair high resistance
or open in “B/R” wire
circuit.
3 1) Check proper connection to P/S control module at
terminal “A3”.
2) If OK, ignition switch ON.
3) Check voltage between “A3” and body ground.
4) Is it 10 – 14 V?
Go to STEP 4. Repair high resistance
or open in “B/W” wire
circuit.
4 1) Ignition switch OFF.
2) Remove combination meter.
3) Remove and check “EPS” bulb.
4) Is “EPS” bulb in good condition?
Go to STEP 5. Replace bulb.
5 1) Check voltage between “A6” terminal and body
ground with “EPS” bulb disconnected.
2) Is it 10 – 14 V?
Repair short to power
circuit in “EPS” light
(“V” wire) circuit.
Go to STEP 6.
6 1) Install “EPS” bulb and combination meter.
2) Check proper connection to P/S control module at
terminal “A6”.
3) If OK, short “A6” terminal to body ground with “A”
connector disconnected.
4) Does “EPS” light turn ON at ignition switch ON?
Go to STEP 7. Repair high resistance
or open in “EPS” light
(“V” wire) circuit.
7 1) Check P/S control module is installed to steering
column assembly securely (check for body ground
of P/S control module).
2) If OK, check resistance between “A1” terminal and
body ground?
3) Is resistance 1 or less?
Repair poor ground
(“B” wire) circuit.
Substitute a known-
good P/S control mod-
ule and recheck.
