Acura RL. Manual - part 808

1. Remove the battery trim (see step 2 under UPPER FENDER TRIM REPLACEMENT ).

2. Hook up the following equipment:



Ammeter, 0-400 A



Voltmeter, 0-20 V (accurate within 0.1 volt)

3. Connect the HDS to the data link connector (DLC) (see step 2 under HOW TO USE THE HDS

(HONDA DIAGNOSTIC SYSTEM) ).

4. Turn the ignition switch ON (II), and select PGM-FI, INSPECTION, then ALL INJECTORS OFF on

the HDS.

5. Set the parking brake, then with the shift lever in the N or P position, turn the ignition switch to

START (III).

Did the starter crank the engine normally?

YES -The starting system is OK. Go to step 12.

NO -Go to step 6.

6. Check the battery condition. Check the electrical connections at the battery, the negative battery cable

to the body, the engine ground cables, and the starter for looseness and corrosion. Then try cranking
the engine again.

Did the starter crank the engine?

YES -Repairing the loose connection corrected the problem. The starting system is OK. Go to step 12.

this procedure.



After this inspection, you must reset the powertrain control module
(PCM). Otherwise, the PCM will continue to stop the fuel injectors from
functioning.



The battery must be in good condition and fully charged.

NO -Check these items:



If the starter will not crank the engine at all, go to step 7.



If the starter cranks the engine erratically or too slowly, go to step 9.



If the starter does not disengage from the torque converter ring gear when you release the key,
replace the starter or remove it, and check for the following:



Solenoid plunger and switch malfunction



Dirty drive gear or damaged overrunning clutch

7. Make sure the shift lever is in the N or P position, then disconnect the BLK/WHT wire from the

starter solenoid S terminal. Connect a jumper wire from the battery positive terminal to the solenoid
terminal.

Did the starter crank the engine?

YES -Go to step 8.

NO -Remove the starter, and repair or replace it as necessary.

8. Check the following items in the order listed until you find the open circuit:



The WHT wire and connectors between the auxiliary under-dash relay holder and the under-
hood fuse/relay box.



The RED wire and connectors between the driver's under-dash fuse/relay box and the auxiliary
under-dash relay holder.



The RED wire, BLK/WHT wire, and connectors between the driver's under-dash fuse/relay box
and the starter.



The ignition switch (see TEST ).



The transmission range switch and connector (see TRANSMISSION RANGE SWITCH
TEST ).

NOTE:

After the open circuit or high resistance in the circuit is found and
repaired, go to step 12.



Starter cut relay 1 and the starter cut relay 2 (see POWER RELAY TEST ).

9. While cranking the engine, check the cranking voltage and the current draw.

Is the cranking voltage greater than or equal to 7.7 V and is the current draw less than or equal to
400 A?

YES -Go to step 10.

NO -Replace the starter, or remove and disassemble it, and check for the following:



Drag in the starter armature



Shorted armature winding



Excessive drag in the engine

10. Check the engine speed while cranking the engine.

Is the engine speed above 100 rpm?

YES -Go to step 11.

NO -Replace the starter, or remove and disassemble it, and check the following until you find the
problem:



Open circuit in starter armature commutator segments



Excessively worn starter brushes



Open circuit in the starter brushes



Dirty or damaged helical splines or drive gear



Faulty drive gear clutch

11. Remove the starter, and inspect its drive gear and the torque converter ring gear for damage. Replace

any damaged parts.

12. Select PCM reset (see PCM RESET ) to cancel ALL INJECTORS OFF on the HDS.

13. Reinstall the battery trim (see step 2 under UPPER FENDER TRIM REPLACEMENT ).

STARTER SOLENOID TEST

1. Make sure you have anti-theft codes for the audio system and navigation system. Make sure the

ignition switch is OFF.

2. Remove the battery trim (see step 2 under UPPER FENDER TRIM REPLACEMENT ).

3. Disconnect the negative cable from the battery.

4. Disconnect the starter cable (A), BLK/WHT wire (B), and motor cable (C).

5. Check the hold-in coil for continuity between the S terminal and the armature housing (ground) (D).

There should be continuity.



If there is continuity, go to step 6.



If there is no continuity, replace the solenoid.

6. Check the pull-in coil for continuity between the S terminal and the M terminal. There should be

continuity.



If there is continuity, the solenoid is OK.



If there is no continuity, replace the solenoid.

7. Reconnect the starter cable, BLK/WHT wire, and motor cable.

8. Connect the negative cable to the battery.

9. Install the battery trim (see step 2 under UPPER FENDER TRIM REPLACEMENT ).

10. Do the steering column position memorization procedure (see STEERING COLUMN POSITION

MEMORIZATION ).

11. Enter the anti-theft codes for the audio system and the navigation system.

STARTER PERFORMANCE TEST

1. Disconnect the wire from the M terminal.

2. Make a connection for this test using the thickest (gauge) wire possible (preferably the same gauge as

used on the vehicle).

NOTE:

To avoid damaging the starter, never leave the battery connected for
more than 10 seconds.
