Description
Electronic Control System (cont'd)
Shift Control
The PCM instantaneously determines which gear should be selected by various signals sent from sensors, and actuatesthe shift control solenoid valves A and B to control shifting. Also. a Grade Logic Control System has been adopted to con-trol shifting in E position while the vehicle is ascending or descending a slope, or reducing speed.

Lock-up Control
From sensor input signals, the PCM determines whether to turn the lock-up ON or OFF, and activates lock-up controlsolenoid valve A and/or B accordingly. The combination of driving signals to lock-up control solenoid valves A and B andthe linear solenoid pressure is shown in the table below.

Troubleshootin g Procedures
Chccking the Diagnostic Trouble Code IDTC)with an OBD ll Scan tool or Honda PGM Tester
when the PCM senses an abnormality in the input or output systems, the pl indicator light in the gauge assembly willblink. When the 16P Data Link Connector (DLC) (located under the dash on the driver,s side) is connected to the OBD llScan Tool or Honda PGM Tester as shown, the scan tool or tester will indicate the Diagnostic Trouble Code (DTC) whenthe ignition switch is turned ON{ll).
lf the El indicator light or the MIL has been reported on, or lf a driveability problem is suspected, follow this procedure:
1. Connect the OBD ll Scan Tool (conforming to SAE J19781 or Honda PGM Tester to rhe 16p DLC. (See the OBD ll ScanTool or Honda PGM Tester user's manual for specific instructions. lf you are using the Honda PGM Tester, make sure itis set to the SAE DTC type.)
2. Turn the ignition switch ON (lll, and observe the DTC on the screen,3, Record all fuel and emission DTCS, A/T DTCS, and freeze data.4 lf there is a fuel and emissions DTC, first checkthe fuel and emissions system as indicated bythe DTC (except for DTCP0700). DTC P0700 means there is one or more A,/T DTC, and no problems were detected in the fuel and emissions cir-cuit of the PCM.
5. Write down the radio station oresets.
6. Reset the memory with the PGM Tester or by removing the BACK UP fuse in the passenger's under-dash fuse/relay boxfor more than 10 seconds.
7. Drive the vehicle for several minutes at speeds over 30 mph (50 km/hr), and then recheck for DTCS. lf the A"/T DTCreturns, go to the Symptom-to Component Chart on pages 14-52 and 14-53 for'96 - 98 models, and pages 14-54 and14-55 for the'99 - 00 models, lf the DTC does not return, there was an intermittent problem within the circuit. Makesure all pins and terminals in the circuit are tight, and then go to step g.
8. Reset the radio preset stations, and set the clock.

Chocking th€ Diagnostic Trouble Code (DTCI
with the Servico Check Conneqtor and Sp€cialTool
When the PCM senses an abnormality in the input or output systems, the @ indicator light in the gauge assembly will blink
When the Service Check Connector (locat€d under the dash on the passengsr side) is connected with the special tool as
shown, the E indicator light will blink the Diagnostic Trouble Code (DTC) when the ignition switch is turned ON (ll).
When the E indicator light has been reported on, connect the Service Check Connector with the special too'.
Then turn ON (ll) the ignition switch and obssrve the E indicator tight.

Codes 1 through 9 are indicated by individual short blinks, Codes 10 and above are indicat€d by a sories of long and short
blinks. One long blink equals 1O short blinks. Add the long and short blinks together to determine th€ code. After deter-
mining the code, refer to the electrical system Symptom-to Component Chart on pages 1+52 and 1+53 for'96 - 98 mod-
els, and 14-54 and 14-55 for the '99 - 00 models.
