INSPECTION PROCEDURE BY INPUT
CHECK SYSTEM
1. Open the glove compartment and connect a voltmeter ;
between terminal for "ETACS" and terminal for ground. -,
2 Check to be sure that voltage should be
output
repeatedly
in the (A) or (B) pattern shown in the figure at the left when
the ignition key is turned -to the ON or ACC position.-

yi
ECU power-supply and ground circuits as described in
ic
check chart No. 1 (Refer to P18-1301).
