DTC detecting condition Trouble area
Battery voltage is lower than lower limit voltage for P/S
control module diagnosis
(1 driving cycle detection logic) • High resistance, open or short in P/S control module
power supply circuit
• Undercharged Battery
• P/S control module
Step Action Yes No
1 Was “EPS System Check” performed? Go to Step 2. Go to “EPS System
Check: ”.
2 1) Check circuit fuse for P/S control module.
2) If OK, measure voltage between positive battery terminal
and vehicle body ground with engine running.
Is voltage 10 V or more?
Go to Step 3. Check charging system
referring to “Generator
Test (Undercharged
Battery Check): in
Section 1J”.
3 1) With ignition switch OFF, disconnect P/S control module
connector (“E49”).
2) Check for proper connection to the P/S control module at
“E49-2” (“BLK” wire) terminal.
3) If OK, then check for high resistance, open or short to
power circuit in “BLK” wire circuit.
Is check result in good condition?
Go to Step 4. Repair “BLK” wire
circuit.
4 1) Remove steering column hole cover with turn ignition
switch OFF.
2) Check for proper connection to the P/S control module at
“E49-1” (“GRN” wire) terminal.
3) Connect P/S control module connector.
4) If OK, check voltage between “E49-1” terminal and body
ground with engine running.
Is voltage 10 V or more?
Check for intermittent
trouble referring to
“Intermittent and Poor
Connection Inspection:
in Section 00”.
If OK, substitute the
original P/S control
module with a known-
good P/S control
module, and then
recheck. Repair poor connection
or high resistance in
“E49-1” (“GRN” wire)
circuit.
