STEP
1 Was "SYSTEM CHECK FLOW TABLE"
performed?
2 Are "EPS" fuses in good condition?
3 1) Remove steering column hole 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.
Is it 10 – 14 V?
4 1) Check proper connection to P/S control
module at terminal "A3".
2) If OK, turn ignition switch to ON position.
3) Check voltage between "A3" and body ground.
Is it 10 – 14 V?
5 1) Turn ignition switch to OFF position.
2) Remove combination meter.
3) Remove and check "EPS" bulb.
Is "EPS" bulb in good condition?
6 1) Check voltage between "A6" terminal and body
ground with "EPS" bulb disconnected.
Is it 10 – 14 V?
7 1) Install "EPS" bulb and combination meter.

position?
8 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.
Is resistance 1 Ω or less?
ACTION YES

good P/S control
module and recheck.
NO
Go to "SYSTEM
CHECK FLOW
TABLE" in this section.
Check short to ground
in "B/R" (for "EPS"

or open in "B/R" wire
circuit.
Repair high resistance
or open in "B/W" wire
circuit.
Replace bulb.
