TABLE B - MALFUNCTION INDICATOR LAMP FLASHES AT IGNITION SWITCH
ON
CIRCUIT
Refer to TABLE-A for System Circuit Diagram.
Step
1
1) Check monitor coupler.
Is it connected diagnosis switch terminal ("8")
and ground terminal ("9") in monitor connector
by jumper wire?
2
1) Check voltage between diagnosis switch
terminal of monitor coupler and body
ground with ignition switch ON.
Is it 10 – 14 V?
TABLE C - MALFUNCTION INDICATOR LAMP DOES NOT FLASH, JUST
REMAINS ON OR JUST REMAINS OFF EVEN WITH DIAGNOSIS SWITCH TER-
MINAL GROUNDED
CIRCUIT
Refer to TABLE-A for System Circuit Diagram.
Step
1
1) Inspect connection between diagnosis
switch and ground terminals on monitor
coupler by jumper wire.
Is it securely connected between them by
jumper wire?
2
1) With ignition switch OFF, disconnect P/S
control module connector ("G24").
2) Check proper connection to P/S control
module at "G24-4" terminal.
3) If OK, check resistance between "G24-4"
("PPL/WHT" wire) terminal and diagnosis
switch terminal of monitor coupler.
Is there continuity?
3
1) Check proper connection to P/S control
module at "G24-2" terminal.
2) If OK, check resistance between "G24-2"
("BLK" wire) terminal and body ground.
Is there continuity?
4
1) Check proper connection to P/S control
module at "G24-5" terminal.
2) If OK, check voltage between "G24-5"
("YEL" wire) terminal and body ground with
ignition switch ON.
Is it 10 – 14 V?

ELECTRICAL POWER STEERING (P/S) SYSTEM 3B1-15
Yes
Disconnect jumper wire
from monitor coupler.
Substitute a known-good
P/S control module and
recheck.
Yes
Go to Step 2.
Go to Step 3.
Go to Step 4.
Substitute a known-good
P/S control module and
recheck.
No
Go to Step 2.
"PPL/WHT" wire circuit
short to ground.
No
Properly connection diag-
nosis switch and ground
terminals on monitor cou-
pler by jumper wire.
"PPL/WHT" wire circuit
open.
"BLK" wire circuit open.
"YEL" wire circuit or inside
of combination meter
short to other circuit or
ground.
