(4) Push the TCS OFF switch to ON. (with TCS mod-
els)
(5) Start the engine.
(6) Shift on the gear position, and keep the vehicle
speed at constant.
(7) Measure signal voltage.
Specified voltage: 2 V, or more
NOTE:
If vehicle speed increases, the width of amplitude (W)
decreases.
NOTE:
The speed difference between front and rear wheels may
light either the ABS or the ABS/TCS warning light, but this
indicates no malfunctions. When AT control diagnosis is
finished, perform the ABS or the ABS/TCS memory clear-
ance procedure of self-diagnosis system.

A: BASIC DIAGNOSTIC CHART
If no trouble codes appear in the on-board diagnostic
operation (although problems have occurred or are
occurring), measure performance characteristics of
sensors, actuators, etc., in the“F”mode (select monitor
function), and compare with the“basic data”to determine
the cause of problems.
Trouble occurs.
No trouble codes appear in on-board diagnostic operation.
Measure each item in select mode function.
Compare measured values with basic data.
Determine item which is outside basic data specifications.
Check sensor and actuator affected.
