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.
