Honda Element. Manual — part 69

When the engine speed is a specified value and the IGP terminal voltage is below a set value when the
alternator is in the 14.5 V mode, and the alternator power generation amount is within the set range, and this
condition continues more than a set time, the ECM/PCM detects a malfunction and a DTC is stored.

ENABLE CONDITIONS

Malfunction Threshold

The IGP terminal voltage is 12.0 V or less, and the alternator power generation amount is within 1.0 % to 50.0
%, for at least 60 seconds.

Driving Pattern

1. Start the engine.

2. Maintain an engine speed of 500 rpm to 3,000 rpm.

3. Turn on the headlights (high beam) and rear window defogger.

Diagnosis Details

Conditions for illuminating the indicator

When a malfunction is detected, the DTC and the freeze frame data are stored in the ECM/PCM memory. The
MIL does not come on.

Conditions for clearing the DTC

The DTC and the freeze frame data can be cleared by using the scan tool Clear command or by disconnecting
the battery.

DTC P16BC: ALTERNATOR FR TERMINAL CIRCUIT/IGP CIRCUIT LOW VOLTAGE

Fig. 201: Charging System Circuit Diagram

General Description

The alternator is driven by the engine, and it generates electricity to supply the necessary power to the electrical
load and to charge the battery. The alternator voltage target values of 14.5 V and 12.5 V are achieved by
switching the alternator control mode (controlled by the engine control module (ECM)/powertrain control

module (PCM)). The alternator output signal is sent to the ECM/PCM, and it varies according to the battery's
state of charge, the electrical load, and the engine speed.

When the engine speed is a specified value and the IGP terminal voltage is below a set value when the
alternator is in the 14.5 V mode, and the alternator power generation amount is a set range or less, and this
condition continues more than a set time, the ECM/PCM detects a malfunction and a DTC is stored.

DTC P1717 (62): ADVANCED DIAGNOSTICS

DTC P1717: OPEN IN TRANSMISSION RANGE SWITCH ATP RVS SWITCH CIRCUIT

Fig. 202: Transmission Range Switch Circuit Diagram

TRANSMISSION RANGE SWITCH CONTACT POINT INPUT MATRIX

General Description

The transmission range switch is attached to the control shaft. Operating the shift lever makes the control shaft
rotate via the shift cable. The A/T gear position indicator indicates which position is selected according to the
Low/High signal combinations which vary based on shift lever position. The control shaft changes the position
of the transmission range switch, activates the manual valve, and switches hydraulic pressure to shift the
transmission through forward/neutral/reverse. The transmission range switch signal is used to determine the
shift schedule. The voltage is 12 V (High) at the powertrain control module (PCM) input terminal when each
transmission range switch position is open, and it is 0 V (Low) when each switch is closed. If the RVS switch is
OPEN with the shift lever in the R position while shifting between the P, R, and N positions, the PCM detects a
RVS switch OPEN failure and a DTC is stored.
