Acura RL (1996-2004 year). Manual — part 317
Performance Test
NOTE: Before starting the following checks, disconnect
the wire from terminal M, and make a connection as
described below using as heavy a wire as possible (prefer-
ably equivalent to the wire used in the vehicle).
Pull-in Coil Test:
Connect the battery as shown. If the starter pinion pops
out, it is working properly.
CAUTION: Do not leave the battery connected for more
than 10 seconds.
Disconnect the wire.
Hold-in Coil Test:
Disconnect the battery from the M terminal. If the pinion
does not retract, the hold-in coil is working properly.
CAUTION: Do not leave the battery connected for more
than 10 seconds.
Retracting Test:
Disconnect the battery also from the body. If the pinion
retracts immediately, it is working properly.
CAUTION: Do not leave the battery connected for more
than 10 seconds.
NOTE: The PCM memory must be reset after reconnect-
ing the battery (see page
).
Starter No-load Test:
1. Clamp the starter firmly in a vise.
2. Connect the starter to the battery as shown in the
diagram below, and confirm that the motor starts
and keeps rotating.
3. If the electric current and motor speed meet the
specifications when the battery voltage is at 11 V,
the starter is working properly.
Specifications:
145 A or less current draw
3,300 rpm or more rpm

Ignition Timing Inspection
SRS components are located in this area. Review the SRS
component locations, precautions, and procedures in the
SRS (
) before performing repairs or service.
1. Start the engine. Hold the engine at 3,000 rpm with
no load (shift lever in or position) until the
radiator fan comes on, then let it idle.
2. Pull out the service check connector located under
the glove box. Connect the GRN/BLK and RED wire
terminals with the special tool.

3. Check the idle speed (see page
).
4. Remove the engine cover (see
).
5. Connect a timing light to the No. 1 ignition coil wires;
while the engine idles, point the timing light toward
the pointer on the timing belt cover.

in or position and electrical systems turned
off.

Idle Speed Check
1. Start the engine. Hold the engine at 3,000 rpm with
no load (shift lever in or ) until the radiator fan
comes on, then let it idle.
2. Connect a tachometer to the test tachometer connec-
tor.

Idle speed: 650 ± 50 rpm with shift lever in position
or and electrical systems turned off.
3. Adjust the idle speed if necessary (see
).
Noise Condenser Capacity Test
1. Use a commercially available condenser tester. Con-
nect the condenser tester probes, and measure the
condenser capacity.
Condenser capacity: 0.47 ± 0.09 microfarads ( F)
POSITIVE TERMINAL
BODY GROUND
(Negative)
NOTE: The noise condenser is intended to reduce
ignition noise. However, condenser failure may cause
the engine to stop running.
2. If not within the specifications, replace the noise con-
denser.
