CONTROL SYSTEM [KL]
MAIN RELAY INSPECTION [KL]
Inspection of Output Voltage
1. If the SST (104 Pin Breakout Box) are used,
check in the following order.
(1) Remove the PCM. (Refer to 01-40B
POWERTRAIN CONTROL MODULE (PCM)
REMOVAL/INSTALLATION [KL].)
(2) Connect the SST (104 Pin Breakout Box) to
the PCM as shown.
W 6 U 1 4 0 W N B
(3) Tighten the connector bolt.
Tightening torque
7.9— 10.7 N m
{80— 100 kgf-cm, 69.5— 95.4 in-lbf)
(4) Turn the ignition switch to ON.
(5) Measure the voltage at PCM terminal 71 and
97.
Specification
Condition
PCM terminal 71 or 97
voltage (V)
Ignition switch OFF Below 1.0
Ignition switch ON B+
(6) If not as specified, check the related harness
and main relay continuity.
2. If the SSTs (NGS tester) are used, check in the
following order.
(1) Connect the
SSTs (NGS tester) to the data
link connector.
W6U140WOX
(2) Turn the ignition switch to ON.
(3) Select the “ PID/DATA MONITOR AND
RECORD” function on the NGS tester display
and press TRIGGER.
(4) Select “VPWR” on the NGS tester display and
press START. The NGS tester measures and
shows the voltage.
Specification
Condition “VPW R” voltage (V)
Ignition switch OFF Below 1.0
Ignition switch ON B+
(5) If not as specified, check the related harness
and main relay continuity.
Inspection of Continuity
1. Remove the main relay.
2. Apply battery positive voltage and check continuity
between terminals of the main relay by using an
ohmmeter.
