DIAGNOSIS
The P/S system in this vehicle is controlled by P/S control module. P/S control module has an on-board diagnostic
system which detects a malfunction in this system.
When diagnosing troubles, be sure to have full understanding of the outline of ON-BOARD DIAGNOSTIC SYSTEM
and each item in PRECAUTION IN DIAGNOSING TROUBLE and execute diagnosis according to SYSTEM
CHECK FLOW TABLE.
ON-BOARD DIAGNOSTIC SYSTEM
P/S control module performs on-board diagnosis (self-diagnosis)
on the system which continuously monitors the control module it-
self and the other P/S system components.
When P/S control module detects a trouble it stores the exact
trouble area in P/S control module memory but this P/S system is
not equipped with malfunction indicator lamp which alert the driver
to the occurrence of the trouble. The trouble area is shown as Diag-
nostic Trouble Code (DTC) and it can be read using analog type
voltmeter (For detail, refer to “DTC CHECK” in this Section.)
PRECAUTIONS IN DIAGNOSING TROUBLES
Take a note of DTC indicated first.
Be sure to read PRECAUTIONS FOR ELECTRONIC CIRCUIT SERVICE in SECTION 0A before inspection
and observe what is written there.
When two or more troubles have occurred, their DTCs are indicated three times each starting with the smallest
code number and up.
DTC 22 (engine speed signal failure) is indicated when ignition switch is ON position and engine is not running
but if indication changes to a normal one when engine is started, it means nothing abnormal.
As DTC is stored in memory of P/S control module, be sure to clear memory after repair by performing the proce-
dure described in DTC CLEARANCE.
